DESIGN OF ALL-BOLTED EXTENDED DOUBLE ANGLE, SINGLE ANGLE, AND
TEE SHEAR CONNECTIONS

By

Adam Higgins

May 2005

Chair: Perry Green
Major Department: Civil and Coastal Engineering

This thesis presents a methodology for the design of all-bolted extended double

angle, single angle, and tee shear connections. The thesis covers only the design of

extended connections that involve beams and girders, but the principles set forth can be

applied to connections to columns as well. Current steel connection design

methodologies do not have standards for the design of extended connections which do

not require that the beam be coped to allow clearance for the girder flange. Coping is an

expensive and time consuming process which fabricators like to avoid if at all possible.

Extended connections are a practical way to avoid coping. Using basic mechanics and

code specific equations, a practical design for all-bolted extended shear connections can

be derived. The derived methodology is used to formulate design tables that simplify the

process. This thesis includes examples of how to use the design tables to design all-

bolted extended connections. The tables include design resistances for a wide range of

angle and tee materials and bolts diameters, as well as different connection types.














CHAPTER 1
INTRODUCTION

1.1 Background

Many fabricators and erectors prefer the use of high strength bolts over welding

which requires more time to make the connection and higher skilled labor. Therefore,

many steel fabricators favor using all-bolted connections in order to eliminate the need

for shop and/or field welding.

Steel connections are categorized as either fully restrained (FR) or partially

restrained (PR). FR connections assume the connections have sufficient stiffness to

maintain the angles between intersecting members (American Institute of Steel

Construction (AISC) 1999). PR connections assume the connections have insufficient

stiffness to maintain the angles between intersecting members (AISC 1999). When

connection restraint is ignored, commonly designated as simple framing, the connections

have the following requirements:

1. The connections and the connected members shall be adequate to resist the factored
gravity loads as "simple beams."

2. The connections and connected members shall be adequate to resist the factored
lateral loads.

3. The connections shall have sufficient inelastic rotation capacity to avoid overload
of fasteners or welds under combined factored gravity and lateral loads.

The scope of this research project covers only shear connections and their behavior.

In the case of typical beam-to-girder shear connections, the beam must be coped

(top coped, bottom coped, or top and bottom coped) in order to provide clearance for the









girder flange/s. Coping requires the flange of the beam be removed to allow for the

necessary clearance. Coping not only requires consideration of other limit states, such as

lateral-torsional buckling or local buckling at the reduced section, but coping incurs extra

cost as well. All-bolted extended shear connections are a possible solution to eliminate

coping.

1.2 Objective and Scope of Work

The purpose of this research project is to determine whether all-bolted extended

shear connections, specifically single angle, double angle, and tee connections, are

feasible. Currently there are no specific provisions in the AISC Manual of Steel

Construction (2001) for extended connections of any type. The purpose is to analytically

simulate the response of all-bolted connections under a range of loading conditions so

that the general behavior of the connection can be established. An analytical

methodology will be developed using the current 3rd Edition AISC-LRFD Specification

and first principles of engineering mechanics (AISC 1999). The results of this procedure

will be used to determine applicable limit states and to develop a rational design

procedure for all-bolted extended single angle, double angle, and tee connections.

The scope of this project includes a review of past research done in the area of

bolted connections and the development of new analytical models based on existing

models developed by previous researchers as well as original models developed at the

University of Florida. The models will be used to develop design criteria for the new

connections, and design strength tables will be developed using the new design criteria.
















CHAPTER 2
LITERATURE REVIEW

A great deal of research has been performed regarding the design and behavior of

steel connections the past 50 years, the results of which have been used to create Chapter

J of the AISC Manual of Steel Construction that deals with joints.

2.1 Connection Types

There are several "standard" types of structural steel connections. They are

generally classified into three behavior categories: rigid, semi-rigid, and simple. The

difference among the three can be shown through a plot of end moment versus end

rotation.

The M-0 curve OABC in Figure 2.1 represents the general behavior of connections.

Segment OA of the M-0 curve is the segment where connections behave as fully-

restrained connection. Connections in this range have an initial rotational restraint

are considered simply and do not develop any significant moment. The two initial

rotational stiffness curves represent the boundaries for a partial-restrained connection. As

the figure shows, no connection is truly fixed or truly pinned, but these assumptions

greatly simplify the design process. This research project deals only with simple

connections which assume that there will be no end moment developed in the beam and

that the beam supports will allow unrestrained rotations.

2.2 Bolted Connections

There are two common joining methods in current steel construction: welds and

bolts. This research project only deals with bolted connections; therefore, the

background information pertains mostly to bolted connections. Bolted connections

became popular during the 1950's because previous research had shown that bolts could

be used to replace rivets in connections (Kulak et al. 1987). Until that time only rivets

were used in connections.

Bolted connections can be tightened to specific levels. The first is a snug tight

connection. The bolt is tightened using an ordinary spud wrench to bring the piles, which

in this case are the angles or tees and the web of the beam, into firm contact (RCSC

2000). Alternately, a bolt can be pretensioned, in which case it is a pretensioned joint. A

bolt must be tightened to its minimum pretension force listed in Table J3.1 of the AISC

Specification (AISC 1999). There is no difference in the strength of the two types of









joints, but pretensioning is usually necessary when the connection is subjected to cyclic

or tension loads (Kulak et al. 1987). Slip critical connections are required to meet the

provisions of Chapter J3.8 of the AISC Specification (AISC 1999). This connection is

designed in order to prevent any slip between the faying surfaces. Early research showed

that high-strength bolts can be used in a connection in the same manner as rivets (Kulak

et al. 1987). This discovery led to the common use of high-strength bolts in connections.

Today bolted connections are very popular because they are relatively inexpensive

compared to field welding, and they are easy to install.

Bolted shear connections are used in modern steel construction, and extensive

research has been conducted on these types of connections (Chen and Lui 1988). There

are various types of common shear connections: double angle, single angle, tee, single

plate, etc.

The connections that are related to this project include double angle, single angle

and tees. Double angle connections are made with two angles, one on each side of the

beam to be supported (AISC 1999). These angles may be bolted or welded to the

supported beam as well as to the supporting member. Single angle connections are made

using an angle on one side of the web of the beam to be supported. This angle is

preferably shop bolted or welded to the supporting member and field bolted to the

supported beam (AISC 1999). Tee connections are made using a structural tee. The tee

is preferably shop bolted or welded to the supporting member and field bolted to the

supported beam (AISC 1999).

Research has shown that almost all rotation is provided in the detail material,

usually either angles or plates (Kennedy 1969). A typical deformed shape can be seen in









Figure 2.2. As Figure 2.2 shows, most of the rotation in the connection occurs in the legs

of the angle that are in the plane of the supporting member. This is relevant because the

behavior of extended connections should be similar. The gage distance for the "in-plane"

legs for extended and normal shear connections is the same.

2.3 Moment-Rotation Behavior of Shear Connections

One possible moment-rotation relationship for bolted double and single angle shear

connections was quantified by Kishi and Chen (1990) using a power model relationship

between moment in the connection and end rotation. The general deformation of the

connection was based on the following assumptions:

1. The center of rotation of the connection was near the mid-depth of the beam during
the first few increments of loading.

2. The deformation and subsequent tearing of the connection angles resulted primarily
from bending moment, and the effect of shear deformation on the connection
behavior was relatively small.

The yield mechanisms depicted in Figure 2.3 were also used in determining the

moment-rotation relationship:

The model was verified by comparison to various experimental results (Kishi and

Chen 1990). The model agrees with Astaneh's recommendations for simple connections,

where a simple connection is one that develops a moment at the beam end less than or

equal to 20% of the fixed end moment (Astaneh 1989). Most experiments, such as the

ones Kishi and Chen used to verify their power model, have been performed for beam-to-

column connections only, and have not been directly performed for beam-to girder

connections.

2.4 Coping of Beams

Beam-to-girder shear connections are quite common in steel structures, but they

can be quite complicated to design. Most beam-to-girder shear connections require that

the beam be coped as shown in Figure 2.4 in order to allow clearance for the girder flange

and to maintain the floor elevation.

A beam cope requires time and incurs cost to make, and it also reduces the strength

of the section that must be accounted for by the designer. This coped section possesses a

reduced bending and torsional stiffness, so that buckling, both local and lateral, need be

considered (Cheng 1993). High stress concentrations at the coped corner can also induce

localized yielding that might cause the beam to fail in inelastic local buckling (Yam et al.

2003).










m/ -Beam Cope













Figure 2.4 Beam Cope

The AISC-LRFD Specification (Appendix F ) requires that coped beams be

checked for flexural yielding and local web buckling at the coped section (AISC 1999).

This is computationally time consuming because it requires that the coped section

properties be calculated. For wide flange sections, this calculation process has been

simplified in the AISC Manual (2001) through design aids which have been created that

provide these reduced coped section properties.

Today, it is also standard practice to grind the coped area smooth after the flame

cutting process in order to avoid the likelihood of fatigue cracks developing if the beam is

placed under cyclic loading.

2.5 Tee Connection Behavior

Much research conducted on shear connections focuses on angles, but there has

been research conducted on the behavior of tees (Astaneh and Nader 1990). Inelastic

analyses of the beams indicate that the end rotation of a simply supported beam

approaches 0.03 radians when the mid-span bending moment reaches 99% of the plastic









moment (Astaneh 1989). Tee connections allow this behavior as long as the tee meets

the following criterion:

3. The bolt diameter to the tab (stem) thickness ratio must be greater than or equal to
two (t > 2). This criterion guarantees that the tab (stem) experiences ductile
bearing failure before the bolts fracture in shear (Thornton 1996).

2.6 Conclusion

The previous research mentioned here has been used to determine a design

methodology for all-bolted extended double angle, single angle, and tee connections.

The Kishi and Chen model shows that the plastic hinge is developed in the in-plane or

girder connected angle legs. This assumption is used in the development of the design

tables. The load passes through the centerline of the girder. The plastic hinge is assumed

to develop at the centerline of the girder which requires that the outstanding leg bolts be

designed for an eccentric load. Prying action can be ignored because the plastic hinge is

developed at the girder web.

The extended connection does not require the beam to be coped, so the limit states

due to coping do not need to be checked. This reduces the amount of work needed to

develop the design tables.














CHAPTER 3
OPTIMUM BAY STUDY

3.1 Bay Studies Program

The Excel spreadsheet Bay Studies 4.1 (AISC 2003) is used to determine a

practical range of beam and girder sizes, as well as connection loadings (factored end

reactions). The spreadsheet provides a range of beam and girder sizes for user defined

parameters such as girder and beam length, loading, composite action, etc. The

spreadsheet also provides a materials cost per beam, so that a price estimate can be

constructed.

3.2 Bay Study Parameters

3.2.1 Bay Geometry

A range of bays from 20 foot x 20 foot to 40 foot x 40 foot is considered practical,

and is used in this study. The bay dimensions are varied in 5-foot increments with no

more than 10 feet between the girder length and beam length in any particular bay and

vice versa. In order to have a comprehensive number of section sizes, the number of

filler beams varies from one per bay to four per bay. The total number of bay geometries

considered is 40.

3.2.2 Steel Deck and Slab Properties

The steel deck properties are constant for the whole study, so that the dead load

weight added by the steel deck and concrete will not be a factor in the study. The 2-inch

deep steel deck is given an average rib width of 6 inches, and a rib spacing of 12 inches.

These values are consistent with typical steel deck used in low to mid-rise steel frame









building construction. The concrete for the slab is 3000 psi concrete with a specific

weight of 145 pounds per cubic foot (pcf). The concrete slab extends 3 inches above the

steel deck, for a total slab depth of 5 inches. The construction is considered to be

unshored, which is a common practice.

3.2.3 Loading

The loading for the bays is broken down into four components: dead load, live

load, superimposed dead load, and construction live load. The dead load is the combined

weight of the steel deck and concrete slab, which is calculated by the spreadsheet to be

51.8 pounds per square foot (psf). The live load is 125 psf which covers a broad range of

loading conditions. The superimposed dead load is 20 psf which is the default value for

the spreadsheet. The construction live load is also 20 psf which is the default value. The

spreadsheet allows for live load reduction, but live load reduction is not considered in the

study.

3.2.4 Vibration Criteria and Deflections

The program allows for vibration to be considered in the design process or for a

vibrations check to be made. The program allows the user to change the percentage of

superimposed dead and live load that participates in damping. Also, the damping ratio

for the floor system may be set by the user as well. No vibration check or design is used

for the study.

The deflections allowed for the beam and girders may also be set by the user. The

limits may be input as either absolute deflections or in limiting deflection ratios, such as

L/240. The spreadsheet checks the deflection from live load, dead load, and

superimposed dead load. The spreadsheet also checks deflections from combined loading









effects. The allowable deflection ratios are kept at the default values of L/240 for the

dead load, and L/360 for the superimposed dead and live loads.

3.2.5 Shear Studs and Composite Action

The spreadsheet allows the user to define the range of composite action allowable

(if any) for the member. The spreadsheet allows a minimum and maximum percentage of

composite action in the member. The minimum for the study is 25% composite action,

and the maximum is 75% composite action. The studs are 3/4-inch in diameter and 4

inches in height and cost $2.50 per stud. This is considered typical for a 5-inch deep slab.

The spacing of the shear studs are within the design criteria given in Chapter I of the

AISC Specification, which is the default value (AISC 1999). The spreadsheet also lets

the users define the spacing limits if they so desire. In this study, the default values are

used.

3.2.6 Member Selection and Camber

The spreadsheet allows the user to define the range of wide flange shapes that may

be selected. The default values are W12 to W33 shapes for beams, and W18 to W33

shapes for girders. The study uses the default values for both the beams and the girders.

The spreadsheet also allows the user to set the amount of camber (if any) that may

be used in the beams and girders. The user can set the minimum and maximum amount

of camber to be used, and the camber increment. The default value for the minimum

camber is 0.75 inches, and the maximum value is 2 inches. The default camber

increment is 0.25 inches. The spreadsheet requires that the amount of dead load to be

cambered be set. The default is 75% of the dead load. The default cost of cambering is

$20.00 per beam for 2 inches of camber. The study uses all the default values for

cambering.

The range of factored end reactions range from 14 kips for a 20-foot x 20-foot bay

with a 5-foot beam spacing to 116 kips for a 40-foot x 40-foot bay with a 20-foot beam

spacing. The average factored end shear is 47 kips.

The wide flange sections in Table 3.1 are chosen because they are the least cost but

not necessarily least weight. The cost of the bay includes the cost of the steel, the cost of

the shear stud installation, and the cost of cambering. All of the defaults for cost are used

and are described earlier in this chapter.

The information from Table 3.1 can be used to reduce the number of all-bolted

extended angle and tee tables given in the appendices of this document, by removing the

tables that can not be used for the wide flange sections given in Table 3.1.
















CHAPTER 4
LIMIT STATES

4.1 Extended Double Angle Connection

Double angles or two-sided connections have certain advantages over one sided

connections. Double angle connections can resist larger end reactions because the

supported member bolts are in double shear and the eccentricity perpendicular to the

beam axis need not be considered for workable gages. The pin in an extended and

standard double angle connection is located at the girder web as shown in Figure 4.1.


Point of Fixity


Release of moment at
girder web


Figure 4.1 Pin and Point of Fixity









Double angle connections usually require that the supported member be coped in

order to make the connection. A connection to a coped beam has three limit states at the

cope that do not occur in a connection to an uncoped beam; lateral-torsional buckling,

local web buckling, and fatigue cracking (Cheng 1993). These limit states are not

considered in the analysis of extended double angle connections because there is no

coping involved. The following limit states are considered in the design of an extended

double angle connection:

1. Shear Yielding
2. Shear Rupture
3. Flexural Yielding
4. Flexural Rupture
5. Block Shear Rupture
6. Bolt Bearing
7. Bolt Slip
8. Bolt Shear

The bolt limit states include effects from the eccentricity of the loading. These

limit states are discussed in more detail in Section 4.4 of this chapter.

4.2 Extended Single Angle Connection

A single angle connection uses one angle to make the connection. Single angle

connections have the following advantages:

4. Shop attachment of the connection elements to the support, simplifying shop
fabrication and erection

5. Reduced material and shop labor requirements

6. Ample erection clearance is provided

7. Excellent safety during erection since double connections often can be eliminated
(AISC 1999)

Single angles also have several disadvantages:

8. The supporting member bolts must be designed as eccentrically loaded









9. Single angles have less capacity because the outstanding leg bolts are in single
shear and only one angle is used in the connection.

As with the double angle connection the supported beam must typically be coped in order

to construct the connection. An extended single angle connection does not require coping

of the supported beam; therefore, limit states for coping the beam are no longer

applicable. An extended single angle connection includes all of the limit states that were

stated previously for extended double angle connections. The point of fixity for a single

angle connection is the same as a double angle connection. Single angle connections also

require that the bolts perpendicular to the beam are designed for shear and moment due to

the eccentricity on these bolts. Therefore, both the supporting and supported bolt lines

must be designed with eccentricity considered.

4.3 Extended Tee Connection

Extended tee connections are very similar to extended single angle connections in

that the supported member bolts are in single shear. Therefore, these two types of

connections have less capacity than an extended double angle connection.

As in the previous types of connections, the line of force in a tee connection acts

through the centerline of the supporting member which is the pin of the connection as

shown in Figure 4.1. Therefore, prying action is not considered in the design of any of

the extended connections. Also, tee connections have two lines of bolts on the supporting

member that are symmetrical, so eccentricity on these bolts is not a consideration. Tees

are available with a wide range of stem lengths making them the most versatile extended

connection type.









4.4 Limit State Calculations

4.4.1 Shear Yielding

Shear yielding is a ductile limit state that is a function of the gross shear area of the

element (Green et al. 2001). For single angles and tees, the shear area is equal to the

following equation:

Av= hata (Eq. 4.1)

ha = the length of the angle or tee

ta = the thickness of the outstanding angle leg or stem thickness

Double angles have twice the shear area of a single angle by virtue of having two legs in

shear. The shear area is used to calculate the shear yielding capacity of the connection.

This equation is shown below:

4Rn = 40.6AvFy (Eq. 4.2)

Fy = yield stress of the detail material

4 = 0.90

The equation given above is Equation J5-3 from the AISC-LRFD Specification

(AISC 1999). The 4 term is a resistance factor that is dependent on the limit state. For

yielding limit states, 4 is 0.90. The yield stress, Fy, is either 36 ksi or 50 ksi for A36 or

A992 steels, respectively (AISC 2001). Angles used in the study are designed using both

A36 and A992 steel while tees are designed with only A992 steel. This limit state is

calculated for a range of angles and tees from 5.50 inches to 35.50 inches in length.

4.4.2 Shear Rupture

Shear rupture is also a limit state for the connection. The failure plane is located

along the line of the bolts in the supported angle leg/s or tee stem; therefore, a reduced or









net area is used for calculating the shear rupture strength of the connection. The net shear

area is calculated using the following equation:

n 1 (Eq. 4.3)
An= ha- n(dh + -) ta
16

n = the number of bolts

dh = the bolt hole diameter

For the calculation of Any the AISC-LRFD Specification requires that 16 of an inch be

added to the nominal bolt hole diameter when calculating net areas (AISC 1999). The net

shear area is the sum of both angles for double angle connections. The shear rupture

capacity is given by the equation below:

4Rn = 0.6AnvFu (Eq. 4.4)

Fu = the ultimate stress of the detail material

4 = 0.75

This equation is also Equation J4-1 in the AISC-LRFD Specification. For rupture limit

states, 4 is 0.75. The ultimate stress, Fu, is either 58 ksi or 65 ksi for A36 and A992

steels, respectively (AISC 2001). The range of angle and tee lengths is the same as for

shear yielding.

4.4.3 Flexural Yielding

Flexural yielding of the outstanding angle leg or tee stem is checked in determining

the design capacity of the extended connections. In standard connections, flexural

yielding need not be considered because the eccentricity of the load is within specified

gage distances (AISC 2001). For most flexural limit states, the plastic section modulus,

Z, is used to determine the flexural design strength. The AISC-LRFD Manual (2001)









allows the designer to use the elastic section modulus, S, as a conservative approximation

when calculating the flexural limit states in connections. The elastic section modulus for

the angles and tees is calculated using Equation 4.5:

S taha2 (Eq. 4.5)
S-
6

The flexural design strength is given by Equation 4.6:

1Mn = WSFy (Eq. 4.6)

S=0.90

In order to compare the flexural limit states to the others the moment is converted

to a load that acts at an eccentricity. The eccentricity, e, varies depending upon the

supported leg or stem length. The eccentricity is assumed to be the distance from the

centerline of the supported bolts to the face of the supported web as shown in Figure 4.2.

Eccentricity, e






I *

I *







Figure 4.2 Moment Eccentricity

The figure shows the dimension that is used to determine the eccentricity.

Therefore, the flexural capacity of the connection is dependent upon the eccentricity









unlike for shear limit states. As the eccentricity increases; the flexural strength decreases.

The connection capacity, R Rn, is therefore:

R Mn (Eq. 4.7)
e

e = eccentricity

4.4.4 Flexural Rupture

Flexural rupture is an ultimate strength limit state. The net elastic section modulus

is conservatively used to determine the section capacity. In Section 15 of the AISC-

LRFD Manual, an equation is provided for the net section modulus for bracket plates

(AISC 2001). The AISC Manual permits this equation to be used to determine the net

elastic section modulus for shear connections. This is a conservative approach because

the equation is for the net elastic section modulus, Snet, not the net plastic modulus. The

equation for Snet is given as Equation 4.8:

t2 2 nn21 + (Eq. 4.8)
s2n(n2-1 dh+ 1
ta 2 16)
Snet ha
6 ha




s = bolt spacing

The equation is found at the bottom of Table 15-2 in the AISC-LRFD Manual. The

equation to determine the flexural rupture is below:

4Mn = 4SnetFu (Eq.4.9)

4 =0.75

The flexural rupture strength of a connection is given in terms of a moment, so the

moment, Mn, must be divided by the load eccentricity shown in Figure 4.2 to calculate









the end reaction. As with flexural yielding, flexural rupture follows the same trend that is

that as the eccentricity increases, the capacity decreases. Therefore the connection

capacity is equal to Equation 4.7.

4.4.5 Block Shear Rupture

Block shear rupture is a limit state in which the failure path includes both an area

subject to shear and an area subject to tension (Green et al. 2001). In standard

connections there are two possible elements that can experience block shear rupture; the

connection element (angle or tee) and the net coped section. Extended connections do

not require the supported member to be coped, so block shear rupture will not occur. The

only element that needs to be checked for block shear rupture is the angle or the tee.

Block shear rupture also has the possibility of occurring across more than one failure

plane, but there is only one possible failure plane for an extended connection. Figure 4.2

shows both the shear and tension failure planes.

Block Shear Rupture
S Failure Tension Plane




E'"_ck Shear Ru _ure
Failure Shear Plne







11\


Figure 4.3 Block Shear Rupture Failure Planes









There are two equations that are used to determine the block shear rupture strength

of a connection. The equation that controls is dependant on values of tension rupture and

shear rupture, and which of the two is greater. All the connections in this research project

are controlled by shear rupture, so Equation J4-3b in the AISC-LRFD Specification is

used to determine the block shear rupture strength (1999). The equation is shown below:

4Rn = [0.6FuAnv + FyAgt] < [[0.6FuAnv + FuAt] (Eq. 4.10)

Any = net area subject to shear

Ag = gross area subject to tension

Ant = net area subject to tension

4 = 0.75

Block shear rupture can be conservatively approximated as the shear rupture strength of

the connection. The gross area in tension, Ag, is very small, and the difference between

the block shear, Any, and the net area for shear rupture is the value of Lo, which is the

clear distance from the outlying bolt and the connection angle or tee edge.

4.4.6 Bolt Bearing

Bolt bearing is concerned with the deformation of material at the loaded edge of the

bolt holes (Green et al. 2001). Bearing capacity of the connection is influenced by the

proximity of the bolt to the loaded edge, as well as, the spacing between the bolts.

The bolt edge distance is assumed to be 1-1/4 inches. This edge distance is the

same as the one given in the double angle tables of Part 10 in the AISC Manual. This

edge distance is the minimum for connections using 3/4-inch diameter through 1-inch

diameter bolts. This makes the connection as small as possible which widens its range of

applicability. Extended connections do not have the same carrying capacity as









equivalent-number-of-bolt standard connections. Therefore, an extra bolt is required in

an extended connection to make up for this loss in strength, which requires more space.

Lengthening the edge distance would add more capacity to an extended connection, but

not enough to overcome the requirement for an additional bolt.

Bolt bearing for the beam and girder are not explicitly checked in the extended

connection tables. These two limit states must be checked separately in order to verify

the design strength of the connection. For both the girder and the beam the bolt hole

deformation will be the limiting factor because there is no chance of the bolt tearing out.

Part 10 of the AISC Manual has numbers for these limit states given in a kips per inch of

web thickness format.

All bolt limit states are treated as eccentrically loaded. Eccentricity produces both

a rotation and a translation of one connection element with respect to the other. The

combined effect of this rotation and translation is equivalent to a rotation about a point

defined as the instantaneous center of rotation (IC). In order to determine the bolt bearing

capacity the instantaneous center (IC) method is utilized. This method includes the

nonlinearity of the bolt deformation. The AISC-LRFD Manual has tables with IC

method coefficients in Chapter 7 (2001). These tables are designed for a bolt group

containing 2 to 12 bolts and eccentricities up to 36 inches. These coefficients are

multiplied by the bearing capacity of a single bolt.

The bolt bearing equation given in the AISC-LRFD Specification as Equation J3-2a

is given below:

4Rn = 1 .2LctaFu < 42.4dhtaFu (Eq. 4.11)

S=0.75









L, = clear distance, in the direction of the force, between the edge of the hole and

the edge of the adjacent hole or edge of the material.

The Equation 4.11 considers bolt hole deformation at service loads, a conservative

assumption. The equation above does not include effects from load eccentricity. The

value from the equation above for one bolt is determined and multiplied by the

appropriate C coefficient for the IC method. The equation is Equation 4.12:



4Rn = QCrn (Eq. 4.12)

4 =0.75

C = IC coefficient

rn = the bearing design strength for one bolt

4.4.7 Bolt Slip

Bolt slip is considered in slip critical connections. In the design tables in the

appendices of this document, slip critical connections for three different hole types are

considered. Equations for bolt slip do not include effects of bolt eccentricity. The slip

critical value for one bolt is determined and multiplied by the C coefficient from the IC

method. The equation for bolt slip is given below:

4Rn = 1.13[tTbNsNb (Eq. 4.13)

4 = resistance factor ranging from 1.0 to 0.85

t = mean slip coefficient (Class A [t = 0.33, Class B [t = 0.5)

Tb = minimum fastener tension given in AISC LRFD Specification Table J3.1

Ns = number of slip planes

Nb = number of bolts









The 4 -factor for standard holes is 1.0, while the 4 -factor for oversized and short-slotted

holes is 0.85. The minimum fastener tension is a function of bolt diameter. The slip

capacity of the connection is the slip capacity of one bolt multiplied by the C coefficient.

4.4.8 Bolt Shear

Bolt shear is applicable to each bolted ply of a connection that is subjected to shear

(Green et al. 2001). The shear strength of a bolt is directly proportional to the number of

interfaces (shear planes) between the plies within the grip of the bolt that a single shear

force is transmitted through. The outstanding legs of double angle connections have two

shear planes, while the outstanding leg or stem for single angle and tee connections have

one shear plane. The equation for bolt shear is shown below:

1Rn = lFvAbNsNb (Eq. 4.14)

4 =0.75

Fv = bolt ultimate shear stress

Ab = nominal cross-sectional area of bolt

Ns = number of shear planes

Nb = number of bolts

As with the other bolt limit states, the bolt shear equation does not include the effects of

load eccentricity. The shear strength of one bolt is calculated and multiplied by the C

coefficient. This is equivalent to Equation 4.12 except the 4 -factor is not applied

because it is applied in Equation 4.14.














CHAPTER 5
EXTENDED DESIGN TABLE CONSTRUCTION

5.1 Extended Single and Double Angle Table Construction

The process that has been used to develop the design tables for single and double

angles is divided into three phases:

10. Determine the applicable limit states for these connections;

11. Calculate the connection strength based on the limit states previously determined;
and,

12. Reduce the data and compile into a series of connection design aid tables.

The first and second phases have been discussed in Chapter 3.

Tables have been developed for six, seven, eight, and nine-inch leg angles; 3/4, 7/8

and, 1-inch diameter ASTM A325/F 1852 and ASTM A490 bolts, and ASTM A36 and

ASTM A992 angle material. Currently, 9-inch angles are not available from steel mills,

but are included because of the possible future demand for longer angle legs if the use of

extended connections is shown to be cost effective. All supporting and supported

members are assumed to be A992 wide flange structural shapes. All edge distances are

assumed to be 1'/4-inch. The controlling limit state is highlighted in the extended angle

connection tables. All the design tables are located in the Appendix section of this

document. The single and double angle tables are categorized by angle material (either

A36 or A992) and bolt diameter (3/4-inch, 7/8-inch, 1-inch).

All connections that appear in the tables have controlling limit states that involve

the bolts or the material around the bolts in the case of bolt bearing. The connection









angles never reach their yield or fracture limit states before a bolt limit state is reached.

For many of the longer outstanding leg connections, the minimum connection strength

(10 kips) specified in Section J1.7 of the AISC-LRFD Specification (AISC 1999) is not

reached before the connection fails. Also, not all wide flange structural shapes allow for

extended angle connections when used as girders. Many heavier wide flange sections

have flanges whose flange width, bf, will not allow for any practical extended connection

to be used. In the tables, all design strength values are provided even though any

connection with a strength less than 10 kips cannot be used.

The third phase of constructing the tables consists of compiling all of the

strengths from each limit state and determining the controlling limit state. All of these

calculations were computed via an Excel Spreadsheet. The tables are categorized by the

following criteria:

* Length of outstanding angle leg
* Number of bolts in a single row
* Bolt type (A325/F1852, A490)
* Connection type (Threads excluded (X), included (N), or slip critical (SC))
* Angle thickness
* Bolt diameter
* Type of bolt hole (STD, OVS, SSLT)

The tables display the overall design strength of the connections, 4 Rn and the

appropriate limit state. Bolt bearing on the beam and girder webs is not considered in the

extended angle design strength tables, and must be checked separately by the designer.

5.2 Extended Tee Table Construction

The extended tee tables are developed using the same methodology as the single

and double angle tables with some exceptions. Tees and angles are similar in that they

both have the same limit states, and that the controlling limit states always involve the









bolts or the material around the bolts in the case of bolt bearing. The load is assumed to

have a line of action through the girder web which would eccentrically load the outlying

or stem bolts. The supporting member bolts are in a state of direct shear. The tee stem

must also be checked for flexural yielding and flexural rupture.

Extended tees pose the challenge of determining what eccentricity to use because

there are such a wide variety of tee sections. Two approaches are used to calculate the

design capacity of an extended tee connection:

1. Specify a rational number of eccentricities that cover most cases of extended
tee connections, i.e. eccentricities that will extend beyond a majority of girder
flanges;

2. Formulate an equation that is a function of eccentricity and the number of
bolts. The equation gives the appropriate eccentricity coefficient that is used
to determine the strength of the connection.

5.2.1 Extended Tee Tables

The extended tee design tables are given in Appendices M through O of this

document. The tee tables have a similar format to the angle tables, with some

differences. Due to the wide range of tees available, any eccentricity is possible. Using

the data from the parametric bay study, a practical range of eccentricities was determined.

The range of eccentricities for the tables ranges from 5 inches to 12 inches. This range

covers numerous beam-to-girder connections found in commercial steel building design.

The designer may also linearly interpolate between the values of eccentricity.

The wide variety of tees also allows for a wide range of stem thicknesses. The

stem thickness is one of the limiting factors in the design of extended tee connections.

The controlling limit state changes depending on the stem thickness. After a certain

limiting thickness is reached, the limit state changes from a bearing limit state to either a

bolt shear or slip critical limit state. The limiting thickness is equal to the shear or slip









capacity divided by the bearing capacity for a one inch thick tee stem. Therefore, the

values given in the tables are in units of either kips per inch of tee stem thickness or in

kips, depending on the controlling limit state. The highlighted rows are in units of kips

and have either bolt shear or bolt slip as the controlling limit state depending on the

connection type. The unhighlighted rows are in units of kips per inch of tee stem

thickness for the bolt bearing limit state.

The AISC Specification requires that tees are configured so that flexing of the tee

accommodates the simple-beam end rotation (AISC 1999). The AISC Manual gives an

equation in Part 9 for maximum tee stem thickness.

db + 1 in. (Eq. 5.1)
ts max = 2 + in.
2 16I

db = bolt diameter (in.)

The tables for extended tees do not check this requirement for ductility. There is the

possibility that because of the extended stem length that this requirement is not

applicable.

5.2.2 Extended Tee Equation

In order to have a more general solution than the one presented by the extended tee

tables, Equation 5.1 has been formulated to determine the design capacity of an extended

tee connection. The limit states for an extended tee connection always involve the bolts

connecting the tee to the supported member. Therefore, a similar approach to the C-

coefficients given in Chapter 7 in the AISC Manual (2001) has been developed.

The formulation involved plotting the IC coefficients for each bolt group (from 2

bolts to 12 bolts). The plots for each group were than curve-fit to determine a general

relationship.

The curves are logarithmic in nature, but a governing equation could not be


determined using all twelve curves. Using the parametric bay study to determine the


highest practical shear reaction, the number of curves was reduced from 11 to 7. The


excluded curves include those using 9 bolts or above, therefore; the retained curves


include only those using between 2 and 8 bolts. The retained curves were bounded


between an eccentricity of 5 and 16 inches because this was deemed the practical range


for extended connections.


The reduced set of curves was fit with logarithmic curves and from that a general

for coefficients Ci and C2. Equations 5.2 and 5.3 give the final expression for


coeffiecents C1 and C2, respectively. The coefficients are a function of the number of


bolts in the tee stem. Both equations are second order equations and are used to calculate


the IC coefficient necessary for a particular connection.

Using Equations 5.1 through 5.3, an instantaneous center coefficient can be

calculated. The IC coefficient is multiplied by the least design strength of one bolt;

determined by the limit states of either bolt shear strength, bearing strength at the bolt

holes, or slip resistance (if the connection is to be slip critical). The design strength is

The equation method of determining the design strength for extended tee

connection is slightly limited. The equations only apply for the number of bolts in the tee

stem ranging from 2 to 8, and the eccentricity of the load must be between 5 and 16

inches.

The following example is intended to show the use of the design tables in the

appendices to design an all-bolted extended double angle connection. The connection to

be designed is taken from the results of the parametric bay study. The problem statement

is given in the following paragraph.

Design the all-bolted double-angle shear connection shown in Figure 6.1. The

connection should be designed as an extended connection. Use A36 material for the

connection angles and 3/4 inch diameter A325 bolts. The connection is carrying a

Step 1- Design Bolts and Angles

Calculate the required length of the outstanding angle leg. Equation 6.1 can be used to

determine the necessary outstanding angle length.

bf (Eq. 6.1)
e = +3.5
2

bf = girder flange width (inches)

6.50
ea +3.5= 6.75 in.
2

For this example, ea is equal to 6.75 inches which requires a 7-inch outstanding angle leg

in order to clear the girder and beam flanges.

Step 2- Select Extended Connection

Use the all-bolted extended double angle design tables and choose an appropriate

connection. Using the tables in Appendix A, a connection can be chosen. A 3-bolt

connection using 5/16-inch thick A36 angles will work.

Rn = 27.9 kips > 19 kips (Eq. 6.2)

The values given in the tables are for the design strength, therefore; they are compared to

the factored loads directly. The controlling limit state is bolt bearing on the outstanding

angle legs which can be seen by the color coding in Appendix A.

Step 3-Check supported beam web

From Table 10-1 in the AISC Manual, for three rows of bolts, beam material of F = 50

ksi and Fu = 65 ksi, and Lev = 1.25 in. and Leh = 1.25 in., and the beam is uncoped (AISC

2001). This is a bolt bearing limit state check on the supported beam web.

Rn = (263 kips/in.X0.235 in.) (Eq. 6.3)


61.8 kips > 19 kips









The supported beam web has sufficient strength and because the beam is uncoped that is

the only limit state for the beam that needs to be checked.

Step 4-Check supporting girder web

From Table 10-1 in the AISC Manual, for three rows of bolts and girder material of Fu

65 ksi (AISC 2001). This is a bolt bearing limit state check on the supporting girder web.

R, = (526 kips/in.X0.350 in.) (Eq. 6.4)

The design of the standard double angle connection is checked by MathCAD

worksheets (Green et al. 2001). The connection requires three 3/4-inch diameter bolts, in

order for the angle to be greater than half the T-depth of the beam.

Rn = 42.8 kips > 19 kips (Eq. 6.5)

The controlling limit state is bolt bearing on the outstanding leg. The detail for the

connection can be seen in Figure 6.3.

The following example is intended to show the use of the design tables in the

appendices to design an all-bolted extended single angle connection. The connection to

be designed is taken from the results of the parametric bay study. The problem statement

is given in the following paragraph.

Design the all-bolted single-angle shear connection shown in Figure 6.4. The

connection should be designed as an extended connection. Use A36 material for the









connection angles and 3/4 inch diameter A325 bolts. The connection is carrying a

factored load of 50 kips, which was determined using the parametric bay study

spreadsheet provided by AISC (AISC 2003). Lastly, draw a detail of the designed

connection.

Step 1-Design Bolts and Angle

First calculate the required length of the angle. Equation 6.1 can be used to determine the

necessary outstanding angle length.

ea = + 3.5 = 7.02 in. (Eq. 6.6)
2

For this example, ea is equal to 7.02 inches which requires a 7-inch outstanding

angle leg in order to clear the girder and beam flanges.

Step 2-Select Extended Connection









Use the all-bolted extended single angle design tables and choose an appropriate

connection. Using the tables in Appendix G, a connection can be chosen. A 6-bolt

connection using a 3/8-inch thick A36 angle will work.

Rn = 58.2 kips > 50 kips

(Eq. 6.7)

Step 3-Check supported beam web

From Table 10-1 in the AISC Manual, for six rows of bolts, beam material of F = 50 ksi

and Fu = 65 ksi, and Lev = 1.25 in. and Leh = 1.25 in., and the beam is uncoped (AISC

2001).

R, = (526 kips/in.X0.395in.) (Eq. 6.8)

=208 kips > 50 kips

The supported beam web has sufficient strength and because the beam is uncoped that is

the only limit state for the beam that needs to be checked.

Step 4-Check supporting girder web

From Table 10-1 in the AISC Manual, for six rows of bolts and girder material ofFy = 50

ksi and Fu = 65 ksi using half the value because this is a single angle connection (AISC

2001)

Rn, = (1050 kips/in.X0.430 in.) (Eq. 6.9)


= 226 kips > 50 kips

The design of the standard single angle connection is checked by MathCAD

bolts, but the beam must be coped top and bottom in order to fit within the girder T-

dimension.

Calculate the required depth of the tee. Equation 6.1 can be used to determine the

For this example, ea is equal to 6.5 inches which requires a 7-inch deep tee in order

to clear the girder and beam flanges.

Step 2-Select Extended Connection

Use the all-bolted extended tee design tables and choose an appropriate connection.

Using the tables in Appendix M, a connection can be chosen. Choose a WT6x25, for this

connection. Now the stem thickness needs to be checked in order to determine which

row on the design table to use. The stem thickness for a WT6x25 is 0.37 inches,









therefore; use the highlighted row because the stem thickness is greater than the limiting

thickness of 0.36 inches. Assume the eccentricity to be 7 inches to be conservative.

4R, = 24.0 kips > 19 kips (Eq. 6.12)

Step 3-Check supported beam web

From Table 10-1 in the AISC Manual, for four rows of bolts, beam material of F = 50

2001).

R,. = (409 kips/in.X0.230 in.) (Eq. 6.13)

= 94.0 kips > 19 kips

The supported beam web has sufficient strength and because the beam is uncoped that is

the only limit state for the beam that needs to be checked.

Step 4-Check supporting girder web

From Table 10-1 in the AISC Manual, for four rows of bolts and girder material of Fy

50 and Fu = 65 ksi, (AISC 2001)

R, =(819 kips/in.X0.300 in.) (Eq. 6.14)

=246 kips > 19 kips

The connection is summarized in Figure 6.8

Step 5-Design Standard Connection

The design of the standard tee connection is checked by MathCAD worksheets

(Green et al. 2001). The connection requires only three 3/4-inch diameter bolts, but the

beam must be coped

Rn = 39.1 kips > 19 kips (Eq. 6.15)









The controlling limit state is bolt bearing on the tee stem. The detail for the


connection can be seen in Figure 6.9.

CHAPTER 7
FINITE ELEMENT ANALYSIS

7.1 Introduction

This chapter presents the results of a finite element study that was conducted on a

single angle bolted connection where the protruded leg of the angle extended beyond the

flange of the supporting girder. The behavior of the extended connection was compared

to that of a standard equal leg angle connection that would be used in a coped beam to

girder connection. The finite element model consisted of three main parts: the

connection angle, bolts and a portion of the supporting girder web. Each of these parts

was modeled with three-dimensional (3D) solid elements. Additionally, the contact

surface between connected elements, e.g. angle and girder web were modeled. The finite

element model incorporated the effects of material and geometric nonlinearity as well as

including the effect of initial bolt pretension on the overall connection behavior.

The finite element analysis was carried out using the latest commercially available

ADINA finite element software package, Version 8.1 (ADINA 2003). This finite

element package has the capability to model complex phenomena such as contact

problems, initial stresses, non-linear material and geometric behavior as well as dynamic

analysis. The user inputs the geometry as a 3D model drawn in a Computer Aided

Design (CAD) environment. Then, after specifying the desired type of elements) and

mesh density, the program automatically generates an optimal finite element mesh.

Once the analytical model is generated the analysis results can be presented in

numerous graphs and plots showing critical behaviors that are identified such as the









applied load-vertical tip displacement behavior and the effective stresses occurring

throughout the model. The basic finite element model was created where the position of

the bolt line in the in-plane angle leg corresponded to that of a standard coped beam to

girder connection. The finite element model was then modified by adding additional

elements to the in-plane angle leg to account for the bolt line being located further away

from the girder web. This model represented the protruded angle leg of an extended

connection where the supported beam would not need to be coped prior to being

connected to the supporting girder. The material strengths used in the models for the

structural shapes consisted of both A36 and A572 Gr. 50 steel. Therefore, the material

steel strength was considered a model parameter. The finite element analysis results for

the various models are compared as well as to the current design procedures that are in

the AISC Manual of Steel Construction (AISC 2001).

7.2 Finite Element Model Development

7.2.1 FE Discretization for Angle

Three-dimensional (3D) solid elements were utilized to model the angle section.

These elements are 8-node elements as described in the ADINA Theory and Modeling

Guide (ADINA 2003). Each node in the solid element has three master degrees of

freedom: X-translation, Y-translation, and Z-translation. The basic finite element mesh

for the angle contained 5830 solid elements and 6320 nodes. The angle mesh detail is

shown in Figure 7.1. The angle section used in the basic model represented a L3/2 x 3/2

x 5/16 and was 9 inches long. This length was chosen since it is representative of a

standard three-bolt shear connection with 1/2 in. edge spacing and 3 in. center-to-center

spacing of the bolts. The 312 inch protruded leg in the basic model was extended to 5

inches in the modified finite element model.









The basic and modified models were developed for a three-bolt connection. A

standard bolt hole diameter was used in each of the models and consisted of holes that

had a 0.8125 inch diameter for 3 inch diameter bolts.

Following a convergence study of the contact problem between the bolts and the

bolt holes, it was determined that four elements would be necessary through the thickness

of the angle leg (Wheeler et al. 2000). Since there were no bolt holes modeled in the

protruded leg, only two elements were used through the thickness in order to decrease the

number of elements used in the finite element mesh of the angle (Mao et al. 2001). A

convergence study was also carried out to determine the required element size to be used

to model the angle section. Three mesh sizes, a coarse, fine, and extra fine mesh were

created with average element sizes of 0.4, 0.3, and 0.2 inches, respectively, along the top

and bottom edges of the angle. It was determined, from the convergence study, that it

would be necessary to use the extra fine mesh in modeling the angle section. Therefore,

with this mesh size thirty elements were generated around the circumference of each of

the bolt holes.

7.2.2 FE Discretization for Girder

Modeling of the supporting girder was simplified to that of modeling its web in

order to decrease the number elements used in the overall finite element model. Three-

dimensional (3D) solid elements were utilized to model the web of the girder, the same

type of elements used to model the angle section. The basic finite element mesh for the

girder web contained 5296 solid elements and 5834 nodes. The girder web was

constructed as a plate with a width of 5/2 inches, height of 11 inches and a thickness of

5/16 inches. The mesh detail is shown in Figure 7.1.









Three bolt holes were modeled in the web of girder to correspond with the three

bolt holes in the angle. The diameter of these bolt holes was also 0.8125 inches.

Following the same convergence study of the contact problem between the bolts and the

bolt holes, it was determined that four elements would be required through the thickness

of the girder web.

Similar to the angle mesh convergence study, three different element sizes were

considered for the girder web mesh. The average element sizes that were evaluated had

dimensions of 0.4, 0.3 and 0.25 inches. Based on the results of the study, the 0.25 inch

element size was chosen for the girder web mesh. Also, in order to match the mesh of

the angle section that was connected to the web of the girder, thirty elements were

generated around the circumference of each of the bolt holes.

7.2.3 FE Discretization for Bolts

High strength structural ASTM A325 and A490 bolts were included as part of the

finite element model. The two types of bolts were each modeled in a similar fashion, the

only difference being their material behavior. Depending on the type of bolt used in the

model, a minimum pretension could be applied to the bolt in accordance with the AISC-

LRFD Specification (AISC 1999). Three-dimensional (3D) solid elements were utilized

to model each of the three bolts. These elements were 8-node elements as described in

the ADINA Theory and Modeling Guide (ADINA 2003) with three master displacement

degrees of freedom per node. The basic finite element mesh for the three bolts included

10251 elements and 11685 nodes. The bolt mesh detail is shown in Figure 7.1.

The diameter of each bolt that was modeled was 3% inch while the diameter of each

bolt head was 114 inch. In addition to the bolt and the bolt head being modeled, the nut

was also included as part of the finite element model. Along the body of the bolt, eight









elements were modeled in order to match the four elements through the thickness of the

angle leg and the other four elements through the thickness of the girder web. Four

elements were generated through the thickness of the bolt head and the nut. In order to

match the angle and girder web mesh, thirty elements were constructed around the body

of the bolt, the bolt head and the nut.

7.3 FE Model Contact Conditions

A contact condition can be specified in ADINA to model the contact behavior

between solid elements and other structural elements such as the truss, beam, shell, plate

and pile elements. Since only 3D solid elements were utilized in the model, the contact

group that was used in the model was the 3D contact group. In this type of contact group,

one of the two contact surfaces that formed is called the contactor surface and the other is

called the target surface. During the loading of the finite element model the two contact

surfaces are expected to come into contact and become a contact pair.

All parts of the bolted-bolted shear connection are connected to each other through

the contact condition. When the applied load from the beam is imparted to the angle, the

angle begins to displace which then causes it to come into contact with the bolts. The

displacement of the outstanding leg of the angle in turn then causes the bolts to come into

contact with the girder. When the bolts are also pretensioned, the bolt heads are brought

into contact with the in-plane leg of the angle, the nuts are brought into contact with the

girder web and the facing elements of the in-plane angle leg and the girder web are

brought into contact prior to the load being applied to the model.

The contact surfaces as described above were defined as surfaces that were initially

in contact or were anticipated to come into contact by the pretensioning of the bolts or

during the application of the load. In order to avoid an overconstrained analysis problem









that is caused when a contactor node belongs to more than one contact surface in a

contact group, a total of 36 surfaces, divided to 8 contact groups, and 20 contact pairs

were constructed as part of the overall finite element model. These contact groups and

contact conditions are described in Tables 7.1 and 7.2 as follows:

Tables 7.1 and 7.2 describe the detailed interactions that occurred in the finite

element analysis. Table 7.1 gives the general description of the eight contact groups that

were included in the model. Table 7.2 gives the detailed interactions between the three

main components that were included in the model and are called Bodies. The girder web

included two Bodies that were numbered 3 and 6. The angle included five Bodies that

were numbered 1, 2, 4, 5 and 10. The bolts included three Bodies that corresponded to

the three bolts that numbered 7, 8 and 9. If no contact pair numbers given in the table

that means that these two surfaces did not come into contact during the analysis.

ADINA has a library of simple Bodies contained within ADINA-M that can be

specified for contact problems. If the Body is of a complex nature it needs to be modeled

by the user. In the bolted-bolted beam-to-girder finite element model that was created

only Body numbers 1 and 3 were taken from the ADINA-M library. The other Body

numbers were more complex and had to be developed from the simple Body definitions

provided in the software. For these remaining complex Bodies, ADINA assigned Face

numbers to each Body (e.g. the simple block Body has six Faces that are assigned Face

numbers 1 through 6). ADINA automatically assigned Face numbers to each complex

Body that was modeled such as the bolt shanks or the in-plane leg of the angle having

three bolt holes. Only through direct observation of the graphical ADINA output could

the automatically assigned Face numbers be identified.

An important distinction between a contactor surface and a target surface is that in

the converged finite element solution, the material overlap at the contactor nodes is zero

while the target nodes can overlap the contactor body (Bathe and Chaudhary 2000).

Therefore, the surfaces in the angle holes were formed as a contactor surface while the









surfaces on the bolts that are in contact with the angle holes were formed as the target

surface. On the other hand, the surfaces on the bolts that are in contact with the girder

web were assigned as the contactor surfaces while the surfaces in the girder web holes

were denoted as the target surface.

The model of the connection with pretensioned bolts meant that there was friction

between the in-plane leg of angle and the girder web. This friction along the contact

surface was handled in the model by assigning a compression force that acts on each

contactor node and that node is allowed to kinematically slide along the target segments

generating a tangential force that is equal to the Coulomb friction force (ADINA 2003).

In ADINA, the user only has to input a Coulomb friction coefficient in the model

definition of the contact group where it is to be considered and then the program

automatically determines the tangential force from the compression force based on the

following equation:

T, = LT (Eq. 7.1)

Where:

Tt = Tangential force

Tn = Normal force

[t = Coulomb friction coefficient

In the finite element model that was created only the friction between the in-plane

leg of angle and the girder web was considered. The Coulomb friction coefficient that

was assumed for this frictional contact was [t = 0.2. The frictional contact between the

bolt heads to the in-plane angle leg as well as the nuts to the girder web was not

considered. This modeling assumption was made since these contact surfaces had a









much smaller surface area than that of the in-plane angle leg being in contact with the

girder web. This assumption also helped to decrease the analysis run time and the

number of iterations that necessary for each time step to converge.

7.4 FE Model Initial Conditions

The three-bolt connection was pretensioned to assure that the leg of the angle was

brought into firm contact with the web of the girder before the vertical load was applied.

In order to accomplish this in the finite element model, an initial stress was applied to the

bolts to create the pretension. Following the ADINA-Theory and Modeling Guide

(ADINA 2003), the initial stress could be done by three different methods: nodal initial

strain, element initial strain or directly applying a pressure load. The direct pressure load

application method was selected because it was easy to apply and the magnitude of the

specified pressure load could be changed. Furthermore, the method accurately reflected

the behavior of the bolts when they are pretensioned, i.e. only the body of the bolt had a

pretension load, not the bolt heads or nuts.

In order to generate the bolt pretension, a pressure load was simultaneously applied

at each bolt head and nut. The pressure load that was applied to the 3 inch diameter bolts

in the finite element model was 10 ksi. This initial condition was established in the first

step of the analysis. After that, in the second step, the pretension load was omitted and

the external vertical load was incrementally applied.

7.5 FE Model Applied Loading

A static analysis solution scheme was performed using ADINA on the finite

element model. This type of solution does not include time dependent effects, so the

specified time step increment in the program was used to define the increment or

intensity of each load step increment. In order to ensure convergence was achieved in the









solution, the number of time steps needed to be small and it was typical for the analysis

runs to use more than 350 time steps in each case.

The finite element model loading was carried out in two steps: Step 1 was

described in Section 7.4 where a pretension load was generated in the bolts, and Step 2 is

described in this section where the external vertical load was applied to the model. The

vertical shear load was applied incrementally from zero until a maximum value was

reached. This maximum load indicated that the bolted-bolted connection had reached its

ultimate load-carrying capacity.

The vertical shear load was transmitted from the beam into the connection angle

through the three bolts attaching it to the protruded leg. These three bolts were modeled

as three load groups and each group consisted of six single loads as shown in Figure 7.2.

The locations of where the vertical loads were applied were determined from the usual

geometry of where the bolt holes would have been if they had been modeled. These

locations in the protruded leg were at a horizontal distance of 2 inches from the heel of

the 312 inch angle leg and 312 inches from the heel of the 5 inch angle leg.

7.6 FE Model Boundary Conditions

There were two types of boundary conditions utilized in the model. The first type

of boundary condition was placed on the vertical edges of the girder web. Recall that its

model definition consisted of 8-node, 3D solid elements with three master degrees of

freedom at each node (X-, Y- and Z-translation). To simulate a fixed type boundary

condition, all the nodal translational degrees of freedom were fixed along these edges

which were away from the portion of the web where the angle was attached. This

boundary condition was generated along the two edges of the girder web that are parallel

to the Z-axis as shown in Figure 7.3.









The second boundary condition was placed on the protruded angle leg. In a real

bolted-bolted connection this protruded leg would be connected to the web of a beam, but

since this web was not modeled, a boundary condition was imposed to simulate this part

of the connection. The inherent stiffness in the connection between the web of the beam

and the protruded angle leg would restrain this part of the connection from twisting or

moving in the X-direction. Therefore, the X-direction movement of the angle was fixed

through the use of a boundary condition imposed on every node that made up the exterior

face of the protruded angle leg. This boundary condition can be seen in Figure 7.3.

7.7 FE Model Material Behavior

The inelastic material behavior of the angle, girder web and bolts were considered

in the finite element model development. Two steel material types, A36 (ASTM 2003?)

and A572 Gr. 50 (ASTM 2003?) were assigned to the angle while only one type of steel

material, A572 Gr. 50 was assigned to the girder web. Again, there were two steel

material types assigned to the bolts either A325 (ASTM 2003?) or A490 (ASTM

2003?). No material coupon tests or bolt tests were conducted for this project so it was

decided that a reasonable way to incorporate the inelastic behavior of the steel materials

was to treat each type as having a bi-linear stress-strain curve (Salmon and Johnson

1996). Regardless of the type of steel material, the Modulus of Elasticity, E, was defined

as having a value of 29,000 ksi. The stress-strain relationships provided in the ADINA

FE models for the A36 steel, A572 Gr. 50 steel, A325 bolt steel and A490 bolt steel are

given in Figures 7.4 through7.7. All of the material bi-linear curves are comprised of two

straight line segments. The first portion represents the elastic behavior and goes from

zero to a point defined by the yield strain and the corresponding yield stress of the

material, (Sy, oy). The second portion represents the inelastic behavior of the material.









This part of the stress-strain curve starts at (sy cy) and is terminated at a point defined

by the ultimate strain and the corresponding ultimate tensile strength of the material, (su,

ou). It was felt that this level of strain would not be exceeded in any of the analyses so

the stress-strain curves did not need to be extended any further than that provided.

Finally, the steel materials for the angle and girder web along with the different bolt

types were arranged into groups and analyzed as shown in the Table 7.4.

7.8 FE Analysis Results

The results from each FE model were post-processed through ADINA-Plot, a

branch of the ADINA finite element software package, Version 8.1 (ADINA 2003). In

order to compare the analysis results from different model configurations a consistent

approach to the data would need to be taken. It was decided that the best way to do this

would be to either: 1) Plot the incremental applied load versus the tip deflection of the

protruded angle leg from different FE models; or 2) Plot the incremental applied load

versus the end rotation of the protruded angle leg from different FE models. The end

rotation of the leg was calculated from the displacement results taken at two nodes on the









toe of the protruded leg. The first node was located at the top corner and the second node

was located at the bottom corer of the protruded leg. The node numbers from the two

different geometric models that were used to determine the end rotation of the angle leg

are shown in the Table 7.5.

Table 7.5 Corner Node Numbering
Model Description Top Corner Node Bottom Corner Node
312 in. Protruded Leg Model 24703 22556
5 in. Protruded Leg Model 27719 22591

The end rotation, 0, of the protruded leg from each analysis result was calculated

using the following the equation:

S op(-Y bottx o (Eq. 7.2)
(9 in +Zbottom Ztop

Where:

Ytop = Displacement of the top corer node in the Y-axis

Bottom = Displacement of the bottom corner node in the Y-axis

Ztop = Displacement of the top corner node in the Z-axis

Zbottom = Displacement of the bottom corner node in the Z-axis

9 in. = Length of the angle

It was necessary to take into account both the Y-axis displacement as well as the Z-axis

displacement in the calculation of end rotation since the protruded angle leg did not

deform solely in its own plane. Figure 7.8 shows the load vs. displacement results of the

Material Group I finite element model with a 5 inch protruded leg where the maximum

displacements reached 0.36 and 0.23 inches in the Y- and Z-axis, respectively when the

maximum applied load reached 34.8 kips. This occurred at time step = 193.









The applied load vs. end rotation was compared for two Material Group I models

that only differed in the length of the protruded angle leg (see Figure 7.9). The model

with the 312 inch protruded leg converged at time step = 277, corresponding to a

maximum applied load of 49.9 kips and an end rotation of 0.054 rad. The model with the

5 inch protruded leg converged at time step = 193, corresponding to a maximum applied

load of 34.8 kips and an end rotation of 0.053 rad.

The next applied load vs. end rotation comparison that was made evaluated the

results from the Material Group I (A490 bolts) and II (A325 bolts) models. The length of

the protruded angle leg in each model was 5 inches. The model with the A325 bolts

reached a convergence limit when time step = 194, corresponding to a maximum applied

load of 35.0 kips and an end rotation of 0.058 rad. In comparison, the model with the

A490 bolts converged at time step = 193, corresponding to a maximum applied load of

34.8 kips and an end rotation of 0.053 rad. The results of this comparison are shown in

Figure 7.10.

The last applied load vs. end rotation comparison that was made evaluated the

results from the Material Group I (A36 angle) and III (A572 Gr. 50 angle) models. The

length of the protruded angle leg in each model was 5 inches. The model with the A36

steel angle reached a convergence limit when time step = 193, corresponding to a

maximum applied load of 34.8 kips and an end rotation of 0.053 rad. In comparison, the

model with the A572 Gr. 50 steel angle converged at time step = 240, corresponding to a

maximum applied load of 43.2 kips and an end rotation of 0.066 rad. Figure 7.11 shows

the comparison between these two analysis results.









Figures 7.12 and 7.13 are smoothed effective stress plots showing the change in

model behavior from the initial time step to the final time step, respectively of the

analysis run with Material Group I and a 312 inch protruded angle leg. At time step =

1.000 there was no externally applied load, only the pretension in the bolts. The

maximum smoothed effective stress was approximately 14 ksi and that was fairly

uniform between the angle, girder web and the bolts. At time step = 193, the maximum

smoothed effective stresses were 65.78 ksi in the angle, 88.14 ksi in the girder web and

132.6 ksi on the bolt shank. The critical stress occurred at the location of the top hole in

the angle leg. This would correspond to reaching a limit state of bolt bearing on the angle

material which is the same limit state that would have been found if using the design

tables in the Appendices.

Figures 7.14 and 7.15 show the maximum smoothed effective stress plots for

analysis runs with Material Groups II and III, respectively and a 312 inch protruded angle

leg. For Material Group II (time step = 194) these stresses were 70.05 ksi in the angle,

88.11 in the girder web and 98.30 ksi on the bolt shank. For Material Group III (time

step = 240) these stresses were 78.91 ksi in the angle, 99.95 ksi in the girder web and

136.8 ksi on the bolt shank. In each case the maximum stress occurred at one of the bolt

hole locations indicating that a limit state of bolt bearing was reached.

One more comparison was made between all the models previously discussed and a

new model where the boundary condition along the vertical edges of the girder web was

changed from being fixed to that of being pinned. Figure 7.16 shows the applied load vs.

end rotation behavior of the new model compared to all the previous results. The pinned

boundary condition has a marked influence on the rotational behavior of the connection






67


whereas the strength of the connection only changed slightly. A convergence limit was

reached in the analysis of this model at time step = 207, corresponding to an applied load

of 37.2 kips and a maximum end rotation of 0.129 rad. Again, the maximum stresses

occurred at the top bolt hole location, but now it was bolt bearing on the girder web.

CHAPTER 8
SUMMARY AND CONCLUSIONS

Extended all-bolted double angle, single angle, and tee connections are a viable

alternative to standard shear connections with coped beams. The connections have a

limited range of applicability, but in low-rise commercial buildings with lightly loaded

bays, an extended connection will be economical. The connections require no new

construction methods or material, so they can be put to use immediately. The

introduction of longer leg or higher yield strength will increase the range where extended

all-bolted connections can be used.

The tables located in the appendices of this document are considered reliable for

design use. The methods that are used to tabulate them are all based on sound theory and

mechanics. It is recommended that before extended all-bolted connections are introduced

into common practice that some confirmatory laboratory testing be conducted. The

results from this testing may require modifications to the assumptions made in the

calculation of the design tables.

Also, more testing is recommended in the area of beam-to-girder connections.

Almost all previous research is oriented towards beam-to-column connections. The

behavior of a beam-to-girder connection will almost certainly vary somewhat from that of

a beam-to-column connection. Beam-to-girder connections are usually made to the web

of the girder and the web of the beam while beam-to column connections connect the

column flange to the beam girder. The stiffnesses between the girder web and the

column flange vary. This may affect the overall connection behavior. This insight may









help with the design of extended connections. Also, the differences between two-sided

connections as with interior girders where there is one connection on either side of the

girder web, and one-sided connections to spandrel girders should be considered during

the testing of beam-to-girder connections.

The design of extended all-bolted double angle, single angle, and tee connections

must be carefully considered. The designer should understand the theory and mechanics

that are involved in the design of these connections. The tables located in the appendices

section are only tools and designers should use their best judgment when selecting the

type of connection to be specified..

xi Abstract of Thesis Presen ted to the Graduate School of the University of Florida in Partial Fulfillment of the Requirements for the Degree of Master of Engineering DESIGN OF ALL-BOLTED EXTENDE D DOUBLE ANGLE, SINGLE ANGLE, AND TEE SHEAR CONNECTIONS By Adam Higgins May 2005 Chair: Perry Green Major Department: Civil and Coastal Engineering This thesis presents a methodology for the design of all-bolted extended double angle, single angle, and tee shear connectio ns. The thesis cove rs only the design of extended connections that involv e beams and girders, but the principles set forth can be applied to connections to columns as well. Current steel connection design methodologies do not have standards for th e design of extended connections which do not require that the beam be coped to allow clearance for the girder flange. Coping is an expensive and time consuming process which fabr icators like to avoid if at all possible. Extended connections are a pr actical way to avoid coping. Using basic mechanics and code specific equations, a pr actical design for all-bolted ex tended shear connections can be derived. The derived methodology is used to formulate design tables that simplify the process. This thesis includes examples of how to use the design tables to design allbolted extended connections. The tables incl ude design resistances for a wide range of angle and tee materials and bolts diameters, as well as different connection types.

1 CHAPTER 1 INTRODUCTION 1.1 Background Many fabricators and erectors prefer the use of high strength bolts over welding which requires more time to make the connect ion and higher skilled labor. Therefore, many steel fabricators favor us ing all-bolted connections in order to eliminate the need for shop and/or field welding. Steel connections are categorized as eith er fully restrained (FR) or partially restrained (PR). FR connections assume the connections have sufficient stiffness to maintain the angles between intersecting members (American Institute of Steel Construction (AISC) 1999). PR connections assume the connections have insufficient stiffness to maintain the angles between intersecting members (AISC 1999). When connection restraint is ignore d, commonly designated as simple framing, the connections have the following requirements: 1. The connections and the connected members sh all be adequate to resist the factored gravity loads as “simple beams.” 2. The connections and connected members sha ll be adequate to resist the factored lateral loads. 3. The connections shall have sufficient inelas tic rotation capacity to avoid overload of fasteners or welds under combined factored gravity and lateral loads. The scope of this research project covers only shear connections and their behavior. In the case of typical beam -to-girder shear connections the beam must be coped (top coped, bottom coped, or top and bottom cope d) in order to provide clearance for the

PAGE 13

2 girder flange/s. Coping requi res the flange of the beam be removed to allow for the necessary clearance. Coping not only requires c onsideration of other limit states, such as lateral-torsional buckling or lo cal buckling at the reduced se ction, but coping incurs extra cost as well. All-bolted extended shear conne ctions are a possible solution to eliminate coping. 1.2 Objective and Scope of Work The purpose of this research project is to determine whether all-bolted extended shear connections, specifically single angle, double angle, and tee connections, are feasible. Currently there are no specific provisions in the AISC Manual of Steel Construction (2001) for extended connections of any t ype. The purpose is to analytically simulate the response of all-bolted connectio ns under a range of loading conditions so that the general behavior of the connec tion can be established. An analytical methodology will be developed using the current 3rd Edition AISC-LRFD Specification and first principles of engineering mechanic s (AISC 1999). The results of this procedure will be used to determine applicable lim it states and to develop a rational design procedure for all-bolted extended single a ngle, double angle, and tee connections. The scope of this project includes a review of past research do ne in the area of bolted connections and the development of new analytical models based on existing models developed by previous researchers as well as original mode ls developed at the University of Florida. The models will be used to develop design criteria for the new connections, and design strength tables will be developed using the new design criteria.

3 CHAPTER 2 LITERATURE REVIEW A great deal of research has been perform ed regarding the design and behavior of steel connections the past 50 years, the results of which have been us ed to create Chapter J of the AISC Manual of Steel Construction that deals with joints. 2.1 Connection Types There are several “standard” types of st ructural steel connections. They are generally classified into three behavior cat egories: rigid, semi-rigid, and simple. The difference among the three can be shown th rough a plot of end moment versus end rotation. Figure 2.1 Rotational Rigidity of Steel Connections (Astaneh 1989) The Mcurve OABC in Figure 2.1 represents th e general behavior of connections. Segment OA of the Mcurve is the segment where connections behave as fullyrestrained connection. Connec tions in this range have an initial rotatio nal restraint

PAGE 15

4 greater than or equal to L EI 18 where E is the materialÂ’s elastic modulus, I is the moment of inertia of the cross-section of the beam and, L is the le ngth of the beam. Connections with an initial rotational rest raint less than or equal to L EI 2 represented by Segment ABC are considered simply and do not develop any significant moment. The two initial rotational stiffness curves repr esent the boundaries for a partialrestrained connection. As the figure shows, no connection is truly fixe d or truly pinned, but these assumptions greatly simplify the design process. This research project deals only with simple connections which assume that there will be no end moment developed in the beam and that the beam supports will allow unrestrained rotations. 2.2 Bolted Connections There are two common joining methods in current steel construction: welds and bolts. This research project only deals with bolted connections; therefore, the background information pertains mostly to bolted connections. Bolted connections became popular during the 1950Â’s because previo us research had shown that bolts could be used to replace rivets in connections (K ulak et al. 1987). Until that time only rivets were used in connections. Bolted connections can be tightened to specific levels. The first is a snug tight connection. The bolt is tightened using an or dinary spud wrench to bring the piles, which in this case are the angles or tees and th e web of the beam, into firm contact (RCSC 2000). Alternately, a bolt can be pretensioned, in which case it is a pr etensioned joint. A bolt must be tightened to its minimum pretension force listed in Table J3.1 of the AISC Specification (AISC 1999). Ther e is no difference in the st rength of the two types of

PAGE 16

5 joints, but pretensioning is usually necessary when the connection is subjected to cyclic or tension loads (Kulak et al 1987). Slip critical connect ions are required to meet the provisions of Chapter J3.8 of the AISC Sp ecification (AISC 1999). This connection is designed in order to prevent any slip between the faying surfaces. Early research showed that high-strength bolts can be used in a conn ection in the same manner as rivets (Kulak et al. 1987). This discovery led to the common use of high-st rength bolts in connections. Today bolted connections are very popular because they are relatively inexpensive compared to field welding, and they are easy to install. Bolted shear connections are used in m odern steel construction, and extensive research has been conducted on these types of connections (Chen and Lui 1988). There are various types of common sh ear connections: double angle, single angle, tee, single plate, etc. The connections that are related to this project include double a ngle, single angle and tees. Double angle connections are made with two angles, one on each side of the beam to be supported (AISC 1999). These angles may be bolted or welded to the supported beam as well as to the supporting member. Single angle connections are made using an angle on one side of the web of th e beam to be supported. This angle is preferably shop bolted or welded to the supporting member and field bolted to the supported beam (AISC 1999). Tee connections are made using a structural tee. The tee is preferably shop bolted or welded to th e supporting member and field bolted to the supported beam (AISC 1999). Research has shown that almost all rotation is provided in the detail material, usually either angles or plat es (Kennedy 1969). A typical deformed shape can be seen in

PAGE 17

6 Figure 2.2. As Figure 2.2 shows, most of the rotation in the connection occurs in the legs of the angle that are in the plane of the suppor ting member. This is relevant because the behavior of extended connections should be si milar. The gage distance for the “in-plane” legs for extended and normal shear connections is the same. Figure 2.2 Deformation of Web Angl e Connection (Kulak et al. 1987) 2.3 Moment-Rotation Behavior of Shear Connections One possible moment-rotation relationship for bolted double and single angle shear connections was quantified by Kishi and Chen (1990) using a power model relationship between moment in the connection and end ro tation. The general deformation of the connection was based on the following assumptions: 1. The center of rotation of the connection wa s near the mid-depth of the beam during the first few increments of loading. 2. The deformation and subsequent tearing of the connection angles resulted primarily from bending moment, and the effect of shear deformation on the connection behavior was relatively small. The yield mechanisms depicted in Figure 2.3 were also used in determining the moment-rotation relationship:

PAGE 20

ki u 0R M (Eq. 2.3) Where: Mu = ultimate moment capacity of connection The model was verified by comparison to va rious experimental results (Kishi and Chen 1990). The model agrees with Astane hÂ’s recommendations for simple connections, where a simple connection is one that develo ps a moment at the beam end less than or equal to 20% of the fixed end moment (Astan eh 1989). Most experiments, such as the ones Kishi and Chen used to verify their pow er model, have been performed for beam-tocolumn connections only, and have not been directly performed for beam-to girder connections. 2.4 Coping of Beams Beam-to-girder shear connections are quite common in steel structures, but they can be quite complicated to design. Most b eam-to-girder shear conne ctions require that the beam be coped as shown in Figure 2.4 in or der to allow clearance for the girder flange and to maintain the floor elevation. A beam cope requires time and incurs cost to make, and it also reduces the strength of the section that must be accounted for by th e designer. This coped section possesses a reduced bending and torsional stiffness, so that buckling, both local and lateral, need be considered (Cheng 1993). High stress concentra tions at the coped corner can also induce localized yielding that might cause the beam to fail in inelastic local buckling (Yam et al. 2003).

PAGE 21

10 Figure 2.4 Beam Cope The AISC-LRFD Specification (Appendix F1) requires that coped beams be checked for flexural yielding and local web buckling at the coped section (AISC 1999). This is computationally time consuming b ecause it requires that the coped section properties be calculated. For wide flange sections, this calculation process has been simplified in the AISC Manual (2001) through design aids which have been created that provide these reduced co ped section properties. Today, it is also standard practice to grind the coped area smooth after the flame cutting process in order to a void the likelihood of fatigue crac ks developing if the beam is placed under cyclic loading. 2.5 Tee Connection Behavior Much research conducted on shear connec tions focuses on angles, but there has been research conducted on the behavior of tees (Astaneh and Nader 1990). Inelastic analyses of the beams indicate that the end rotation of a simply supported beam approaches 0.03 radians when the mid-span bending moment reaches 99% of the plastic

PAGE 22

11 moment (Astaneh 1989). Tee connections allo w this behavior as long as the tee meets the following criterion: 3. The bolt diameter to the tab (stem) thickness ratio must be greate r than or equal to two 2 t d. This criterion guarantees that the tab (stem) experiences ductile bearing failure before the bolts fracture in shear (Thornton 1996). 2.6 Conclusion The previous research mentioned here has been used to determine a design methodology for all-bolted extended double angl e, single angle, and tee connections. The Kishi and Chen model shows that the plastic hinge is developed in the in-plane or girder connected angle legs. This assumpti on is used in the development of the design tables. The load passes through the centerline of the girder. The plastic hinge is assumed to develop at the centerline of the girder which requires that the outstanding leg bolts be designed for an eccentric load. Prying action can be ignored because the plastic hinge is developed at the girder web. The extended connection does not require the b eam to be coped, so the limit states due to coping do not need to be checked. This reduces the amount of work needed to develop the design tables.

12 CHAPTER 3 OPTIMUM BAY STUDY 3.1 Bay Studies Program The Excel spreadsheet Bay Studies 4.1 (AISC 2003) is used to determine a practical range of beam and girder sizes, as well as connection lo adings (factored end reactions). The spreadsheet provides a range of beam and girder si zes for user defined parameters such as girder and beam lengt h, loading, composite action, etc. The spreadsheet also provides a materials cost per beam, so that a price estimate can be constructed. 3.2 Bay Study Parameters 3.2.1 Bay Geometry A range of bays from 20 foot x 20 foot to 40 foot x 40 foot is considered practical, and is used in this study. The bay dimensions are varied in 5-foot increments with no more than 10 feet between the girder lengt h and beam length in any particular bay and vice versa. In order to have a comprehens ive number of section sizes, the number of filler beams varies from one per bay to four per bay. The total number of bay geometries considered is 40. 3.2.2 Steel Deck and Slab Properties The steel deck properties are constant for the whole study, so that the dead load weight added by the steel deck and concrete will not be a factor in the study. The 2-inch deep steel deck is given an average rib width of 6 inches, and a rib spacing of 12 inches. These values are consistent with typical steel deck used in low to mid-rise steel frame

PAGE 24

13 building construction. The concrete for th e slab is 3000 psi concrete with a specific weight of 145 pounds per cubic foot (pcf). Th e concrete slab extends 3 inches above the steel deck, for a total slab depth of 5 inches. The construction is considered to be unshored, which is a common practice. 3.2.3 Loading The loading for the bays is broken down into four components: dead load, live load, superimposed dead load, and construction live load. The dead load is the combined weight of the steel deck and concrete slab, which is calcul ated by the spreadsheet to be 51.8 pounds per square foot (psf). The live lo ad is 125 psf which covers a broad range of loading conditions. The superimposed dead lo ad is 20 psf which is the default value for the spreadsheet. The construction live load is also 20 psf whic h is the default value. The spreadsheet allows for live load reduction, bu t live load reduction is not considered in the study. 3.2.4 Vibration Criteria and Deflections The program allows for vibration to be c onsidered in the design process or for a vibrations check to be made. The program al lows the user to change the percentage of superimposed dead and live load that partic ipates in damping. Also, the damping ratio for the floor system may be set by the user as well. No vibration ch eck or design is used for the study. The deflections allowed for the beam and gi rders may also be set by the user. The limits may be input as either absolute deflectio ns or in limiting defl ection ratios, such as L/240. The spreadsheet checks the defl ection from live load, dead load, and superimposed dead load. The spreadsheet al so checks deflections from combined loading

PAGE 25

14 effects. The allowable deflection ratios are kept at the default values of L/240 for the dead load, and L/360 for the supe rimposed dead and live loads. 3.2.5 Shear Studs and Composite Action The spreadsheet allows the user to define the range of composite action allowable (if any) for the member. The spreadsheet a llows a minimum and maximum percentage of composite action in the member. The minimu m for the study is 25% composite action, and the maximum is 75% composite action. The studs are 3/4-inch in diameter and 4 inches in height and cost $2.50 per stud. This is considered typical fo r a 5-inch deep slab. The spacing of the shear studs are within the design criteria given in Chapter I of the AISC Specification, which is the default va lue (AISC 1999). The spreadsheet also lets the users define the spacing limits if they so de sire. In this study, the default values are used. 3.2.6 Member Selection and Camber The spreadsheet allows the user to define the range of wide flange shapes that may be selected. The default values are W12 to W33 shapes for beams, and W18 to W33 shapes for girders. The study uses the default values for both the beams and the girders. The spreadsheet also allows the user to set the amount of camber (if any) that may be used in the beams and girders. The user can set the mini mum and maximum amount of camber to be used, and the camber increment. The default value for the minimum camber is 0.75 inches, and the maximum va lue is 2 inches. The default camber increment is 0.25 inches. The spreadsheet re quires that the amount of dead load to be cambered be set. The default is 75% of the dead load. The default cost of cambering is $20.00 per beam for 2 inches of camber. Th e study uses all the default values for cambering.

An example is given in Figure 3.1: Figure 3.1 Bay Studies 4.1 (2003) Results fo r 20-Foot by 20-Foot Bay with a 10-Foot Beam Spacing The spreadsheet also provides the calculation worksheet for the beams and girders as shown in Figure 3.2. The reactions, beam sizes, and girder sizes are recorded and the data is reduced for the 40 cases. Table 3.1 shows the reduced da ta from the optimum bay study. The range

The average factored end shear is 47 kips. The wide flange sections in Table 3.1 are chosen because they are the least cost but not necessarily least weight. The cost of the bay includes the cost of the steel, the cost of the shear stud installation, and the cost of cambe ring. All of the defaults for cost are used and are described earlie r in this chapter. The information from Table 3.1 can be used to reduce the number of all-bolted extended angle and tee tables given in the a ppendices of this document, by removing the tables that can not be used for the wide flange sections given in Table 3.1.

PAGE 31

20 CHAPTER 4 LIMIT STATES 4.1 Extended Double Angle Connection Double angles or two-sided connections have certain advantages over one sided connections. Double angle connections can resist larger end r eactions because the supported member bolts are in double shear and the eccentricity perpendicular to the beam axis need not be considered for work able gages. The pin in an extended and standard double angle connecti on is located at the girder web as shown in Figure 4.1. Figure 4.1 Pin and Point of Fixity

PAGE 32

21 Double angle connections usually require that the supported member be coped in order to make the connection. A connection to a coped beam has three limit states at the cope that do not occur in a connection to an uncoped beam; lateral-torsional buckling, local web buckling, and fatigue cracking (Cheng 1993). These limit states are not considered in the analysis of extended double angle connections because there is no coping involved. The following limit states ar e considered in the design of an extended double angle connection: 1. Shear Yielding 2. Shear Rupture 3. Flexural Yielding 4. Flexural Rupture 5. Block Shear Rupture 6. Bolt Bearing 7. Bolt Slip 8. Bolt Shear The bolt limit states include effects from the eccentricity of the loading. These limit states are discussed in more detail in Section 4.4 of this chapter. 4.2 Extended Single Angle Connection A single angle connection uses one angle to make the connection. Single angle connections have the following advantages: 4. Shop attachment of the connection elem ents to the support, simplifying shop fabrication and erection 5. Reduced material and shop labor requirements 6. Ample erection clearance is provided 7. Excellent safety during erection since doubl e connections often can be eliminated (AISC 1999) Single angles also have several disadvantages: 8. The supporting member bolts must be designed as eccentrically loaded

PAGE 33

22 9. Single angles have less capacity becaus e the outstanding leg bolts are in single shear and only one angle is used in the connection. As with the double angle connection the supporte d beam must typically be coped in order to construct the connection. An extended single angle connection does not require coping of the supported beam; therefore, limit st ates for coping the beam are no longer applicable. An extended single angle connection includes all of the limit states that were stated previously for extended double angle conn ections. The point of fixity for a single angle connection is the same as a double angle connection. Single an gle connections also require that the bolts perpendicular to the b eam are designed for shear and moment due to the eccentricity on thes e bolts. Therefore, both the s upporting and supported bolt lines must be designed with eccentricity considered. 4.3 Extended Tee Connection Extended tee connections are very similar to extended single angle connections in that the supported member bolts are in si ngle shear. Therefore, these two types of connections have less capacity than an extended double angle connection. As in the previous types of connections, the line of force in a tee connection acts through the centerline of the supporting member which is the pin of the connection as shown in Figure 4.1. Therefore, prying action is not considered in the design of any of the extended connections. Also, tee connections have two lines of bolts on the supporting member that are symmetrical, so eccentricity on these bolts is not a consideration. Tees are available with a wide range of stem le ngths making them the most versatile extended connection type.

PAGE 34

234.4 Limit State Calculations 4.4.1 Shear Yielding Shear yielding is a ductile limit state that is a function of the gr oss shear area of the element (Green et al. 2001). For single angl es and tees, the shear area is equal to the following equation: a a vt h A (Eq. 4.1) ha = the length of the angle or tee ta = the thickness of the outstanding angle leg or stem thickness Double angles have twice the shear area of a si ngle angle by virtue of having two legs in shear. The shear area is used to calculate th e shear yielding capacity of the connection. This equation is shown below: y v nF A 6 0 R (Eq. 4.2) Fy = yield stress of the detail material = 0.90 The equation given above is Equation J5-3 from the AISC-LRFD Specification (AISC 1999). The term is a resistance f actor that is dependent on the limit state. For yielding limit states, is 0.90. The yield stress, Fy, is either 36 ksi or 50 ksi for A36 or A992 steels, respectively (AISC 2001). Angles us ed in the study are designed using both A36 and A992 steel while tees are designed with only A992 steel. This limit state is calculated for a range of angles and tees from 5.50 inches to 35.50 inches in length. 4.4.2 Shear Rupture Shear rupture is also a limit state for the connection. The failure plane is located along the line of the bolts in th e supported angle leg/s or tee stem; therefore, a reduced or

PAGE 35

24 net area is used for calculating the shear ruptur e strength of the connection. The net shear area is calculated using the following equation: a h a nvt ) 16 1 d ( n h A (Eq. 4.3) n = the number of bolts dh = the bolt hole diameter For the calculation of Anv the AISC-LRFD Specification requires that 16 1 of an inch be added to the nominal bolt hole diameter when calculating net areas (AISC 1999). The net shear area is the sum of both angles for double angle connections. The shear rupture capacity is given by the equation below: u nv nF A 6 0 R (Eq. 4.4) Fu = the ultimate stress of the detail material = 0.75 This equation is also Equation J4-1 in th e AISC-LRFD Specification. For rupture limit states, is 0.75. The ultimate stress, Fu, is either 58 ksi or 65 ksi for A36 and A992 steels, respectively (AISC 2001). The range of angle and tee lengths is the same as for shear yielding. 4.4.3 Flexural Yielding Flexural yielding of the outstanding angle le g or tee stem is checked in determining the design capacity of the extended connectio ns. In standard c onnections, flexural yielding need not be considered because the e ccentricity of the load is within specified gage distances (AISC 2001). For most flexur al limit states, the plastic section modulus, Z, is used to determine the flexural de sign strength. The AISC-LRFD Manual (2001)

PAGE 36

25 allows the designer to use the elastic secti on modulus, S, as a conservative approximation when calculating the flexural limit states in connections. The elastic section modulus for the angles and tees is calc ulated using Equation 4.5: 6 h t S2 a a (Eq. 4.5) The flexural design strength is given by Equation 4.6: y nSF M (Eq. 4.6) = 0.90 In order to compare the flexural limit stat es to the others the moment is converted to a load that acts at an eccentricity. The eccentricity e, varies depending upon the supported leg or stem length. The eccentricity is assumed to be the distance from the centerline of the supported bolts to the face of the supported web as shown in Figure 4.2. Figure 4.2 Moment Eccentricity The figure shows the dimension that is used to determine the eccentricity. Therefore, the flexural capacity of the connection is dependent upon the eccentricity

PAGE 37

26 unlike for shear limit states. As the eccentricity increases; the flexural strength decreases. The connection capacity, Rn, is therefore: e M Rn n (Eq. 4.7) e = eccentricity 4.4.4 Flexural Rupture Flexural rupture is an ultimate strength limit state. The net elastic section modulus is conservatively used to determine the sect ion capacity. In Section 15 of the AISCLRFD Manual, an equation is provided for the net section modulus for bracket plates (AISC 2001). The AISC Manual permits this e quation to be used to determine the net elastic section modulus for shear connections. This is a co nservative approach because the equation is for the net elastic section modulus, Snet, not the net plastic modulus. The equation for Snet is given as Equation 4.8: a h 2 2 2 a a neth 16 1 d 1 n n s h 6 t S (Eq. 4.8) s = bolt spacing The equation is found at the bottom of Ta ble 15-2 in the AISC-LRFD Manual. The equation to determine the fl exural rupture is below: u net nF S M (Eq.4.9) = 0.75 The flexural rupture strength of a connecti on is given in terms of a moment, so the moment, Mn, must be divided by the load eccentric ity shown in Figure 4.2 to calculate

PAGE 38

27 the end reaction. As with flexural yielding, fl exural rupture follows the same trend that is that as the eccentricity increases, the cap acity decreases. Ther efore the connection capacity is equal to Equation 4.7. 4.4.5 Block Shear Rupture Block shear rupture is a limi t state in which the failure path includes both an area subject to shear and an area subject to tension (Green et al. 2001). In standard connections there are two possibl e elements that can experien ce block shear rupture; the connection element (angle or tee) and the ne t coped section. Extended connections do not require the supported member to be coped, so block shear rupture will not occur. The only element that needs to be checked for bloc k shear rupture is the angle or the tee. Block shear rupture also has the possibility of occurring across more than one failure plane, but there is only one possible failure plane for an extended connection. Figure 4.2 shows both the shear and tension failure planes. Figure 4.3 Block Shear R upture Failure Planes

PAGE 39

28 There are two equations that are used to determine the block sh ear rupture strength of a connection. The equation that controls is dependant on values of tension rupture and shear rupture, and which of the two is greater. All the connections in this research project are controlled by shear rupture, so Equati on J4-3b in the AISC-LRFD Specification is used to determine the block shear rupture st rength (1999). The equa tion is shown below: nt u nv u gt y nv u nA F A F 6 0 A F A F 6 0 R (Eq. 4.10) Anv = net area subject to shear Agt = gross area subject to tension Ant = net area subject to tension = 0.75 Block shear rupture can be cons ervatively approximated as the shear rupture strength of the connection. The gross area in tension, Agt, is very small, and the difference between the block shear, Anv, and the net area for shear rupture is the value of Lc, which is the clear distance from the outlying bolt and the connection angle or tee edge. 4.4.6 Bolt Bearing Bolt bearing is concerned with the deformati on of material at the loaded edge of the bolt holes (Green et al. 2001). Bearing capac ity of the connection is influenced by the proximity of the bolt to the loaded edge, as well as, the spacing between the bolts. The bolt edge distance is assumed to be 1-1/4 inches. This edge distance is the same as the one given in the double angle tabl es of Part 10 in the AISC Manual. This edge distance is the minimum for connectio ns using 3/4-inch diameter through 1-inch diameter bolts. This makes the connection as small as possible which widens its range of applicability. Extended c onnections do not have the same carrying capacity as

PAGE 40

29 equivalent-number-of-bolt standard connections. Therefore, an extra bolt is required in an extended connection to make up for this lo ss in strength, which requires more space. Lengthening the edge distance would add more capacity to an exte nded connection, but not enough to overcome the requirement for an additional bolt. Bolt bearing for the beam and girder are not explicitly chec ked in the extended connection tables. These two limit states must be checked separately in order to verify the design strength of the connection. For both the girder and the beam the bolt hole deformation will be the limiting factor because there is no chance of the bolt tearing out. Part 10 of the AISC Manual has numbers for thes e limit states given in a kips per inch of web thickness format. All bolt limit states are treated as eccentr ically loaded. Eccentricity produces both a rotation and a translation of one connection element with respect to the other. The combined effect of this rotation and translat ion is equivalent to a rotation about a point defined as the instantaneous cen ter of rotation (IC). In order to determine the bolt bearing capacity the instantane ous center (IC) method is utilized. This method includes the nonlinearity of the bolt deformation. Th e AISC-LRFD Manual has tables with IC method coefficients in Chapter 7 (2001). These tables are designed for a bolt group containing 2 to 12 bolts and eccentricities up to 36 inches. These coefficients are multiplied by the bearing capacity of a single bolt. The bolt bearing equation given in the AI SC-LRFD Specification as Equation J3-2a is given below: u a h u a c nF t d 4 2 F t L 2 1 R (Eq. 4.11) = 0.75

PAGE 41

30 Lc = clear distance, in the direction of th e force, between the edge of the hole and the edge of the adjacent hole or edge of the material. The Equation 4.11 considers bolt hole deforma tion at service loads, a conservative assumption. The equation above does not incl ude effects from load eccentricity. The value from the equation above for one bolt is determined and multiplied by the appropriate C coefficient for the IC me thod. The equation is Equation 4.12: n nCr R (Eq. 4.12) = 0.75 C = IC coefficient rn = the bearing design strength for one bolt 4.4.7 Bolt Slip Bolt slip is considered in slip critical connections. In the design tables in the appendices of this document, slip critical c onnections for three di fferent hole types are considered. Equations for bolt slip do not include effects of bolt eccentricity. The slip critical value for one bolt is determined a nd multiplied by the C coefficient from the IC method. The equation for bo lt slip is given below: b s b nN N T 13 1 R (Eq. 4.13) = resistance factor ra nging from 1.0 to 0.85 = mean slip coefficient (Class A = 0.33, Class B = 0.5) Tb = minimum fastener tension given in AISC LRFD Specification Table J3.1 Ns = number of slip planes Nb = number of bolts

PAGE 42

31 The -factor for standard holes is 1.0, while the -factor for oversized and short-slotted holes is 0.85. The minimum fastener tensi on is a function of bolt diameter. The slip capacity of the connection is the slip capacity of one bolt multiplied by the C coefficient. 4.4.8 Bolt Shear Bolt shear is applicable to each bolted ply of a connection that is subjected to shear (Green et al. 2001). The shear strength of a bolt is directly proportional to the number of interfaces (shear planes) between the plies within the grip of the bolt that a single shear force is transmitted through. The outstanding legs of double angle connections have two shear planes, while the outstanding leg or st em for single angle and tee connections have one shear plane. The equation for bolt shear is shown below: b s b v nN N A F R (Eq. 4.14) = 0.75 Fv = bolt ultimate shear stress Ab = nominal cross-sectional area of bolt Ns = number of shear planes Nb = number of bolts As with the other bolt limit states, the bolt sh ear equation does not include the effects of load eccentricity. The shear strength of one bolt is calculated and multiplied by the C coefficient. This is equivalent to Equation 4.12 except the -factor is not applied because it is applied in Equation 4.14.

32 CHAPTER 5 EXTENDED DESIGN TA BLE CONSTRUCTION 5.1 Extended Single and Double Angle Table Construction The process that has been used to deve lop the design tables for single and double angles is divided into three phases: 10. Determine the applicable limit states for these connections; 11. Calculate the connection strength based on the limit states previously determined; and, 12. Reduce the data and compile into a seri es of connection design aid tables. The first and second phases have b een discussed in Chapter 3. Tables have been developed for six, seven, eight, and nine-inch leg angles; 3/4, 7/8 and, 1-inch diameter ASTM A325/F1852 and ASTM A490 bolts, and ASTM A36 and ASTM A992 angle material. Currently, 9-inch angles are not available from steel mills, but are included because of the possible future demand for longer angle legs if the use of extended connections is shown to be cost effective. All s upporting and supported members are assumed to be A992 wide flange structural shapes. A ll edge distances are assumed to be 1-inch. The controlling lim it state is highlighted in the extended angle connection tables. All the design tables ar e located in the Appendix section of this document. The single and double angle tables are categorized by angl e material (either A36 or A992) and bolt diameter (3 /4-inch, 7/8-inch, 1-inch). All connections that appear in the tables have control ling limit states that involve the bolts or the material around the bolts in the case of bolt bearing. The connection

PAGE 44

33 angles never reach their yield or fracture limit states before a bolt limit state is reached. For many of the longer outstanding leg conn ections, the minimum connection strength (10 kips) specified in Section J1.7 of th e AISC-LRFD Specification (AISC 1999) is not reached before the connection fails. Also, not all wide flange structural shapes allow for extended angle connections when used as gird ers. Many heavier wide flange sections have flanges whose flange width, bf, will not allow for any practical extended connection to be used. In the tables, all design st rength values are provided even though any connection with a strength less than 10 kips cannot be used. The third phase of constr ucting the tables consists of compiling all of the strengths from each limit state and determining the controlling limit st ate. All of these calculations were computed via an Excel Spre adsheet. The tables are categorized by the following criteria: Length of outstanding angle leg Number of bolts in a single row Bolt type (A325/F1852, A490) Connection type (Threads ex cluded (X), included (N), or slip critical (SC)) Angle thickness Bolt diameter Type of bolt hole (STD, OVS, SSLT) The tables display the overall de sign strength of the connections, Rn and the appropriate limit state. Bolt bearing on the b eam and girder webs is not considered in the extended angle design strength tables, and must be checked separately by the designer. 5.2 Extended Tee Table Construction The extended tee tables are developed us ing the same methodology as the single and double angle tables with some exceptions. Tees and angles are si milar in that they both have the same limit states, and that th e controlling limit states always involve the

PAGE 45

34 bolts or the material around the bolts in the case of bolt beari ng. The load is assumed to have a line of action through the girder web which would ecc entrically load the outlying or stem bolts. The supporting member bolts are in a state of direct shear. The tee stem must also be checked for flexural yielding and flexural rupture. Extended tees pose the challenge of dete rmining what eccentricity to use because there are such a wide variety of tee sections. Two approach es are used to calculate the design capacity of an ex tended tee connection: 1. Specify a rational number of eccentricities that cover most cases of extended tee connections, i.e. eccentricities that will extend beyond a majority of girder flanges; 2. Formulate an equation that is a func tion of eccentricity and the number of bolts. The equation gives the appropriate eccentricity coefficient that is used to determine the strength of the connection. 5.2.1 Extended Tee Tables The extended tee design tables are give n in Appendices M through O of this document. The tee tables have a similar format to the angle tables, with some differences. Due to the wide range of tees av ailable, any eccentricity is possible. Using the data from the parametric bay study, a pr actical range of eccentric ities was determined. The range of eccentricities for the tables ranges from 5 inches to 12 inches. This range covers numerous beam-to-girder connections found in commercial steel building design. The designer may also linearly interpol ate between the values of eccentricity. The wide variety of tees also allows fo r a wide range of stem thicknesses. The stem thickness is one of the limiting factors in the design of extended tee connections. The controlling limit state changes depending on the stem thickness. After a certain limiting thickness is reached, the limit state ch anges from a bearing limit state to either a bolt shear or slip critical lim it state. The limiting thickness is equal to the shear or slip

PAGE 46

35 capacity divided by the bearing capacity for a one inch thick tee stem. Therefore, the values given in the tables are in units of eith er kips per inch of tee stem thickness or in kips, depending on the controlli ng limit state. The highlighted rows are in units of kips and have either bolt shear or bolt slip as the controlling limit state depending on the connection type. The unhighlighted rows are in units of kips per inch of tee stem thickness for the bolt bearing limit state. The AISC Specification requires that tees ar e configured so that flexing of the tee accommodates the simple-beam end rotation (AISC 1999). The AISC Manual gives an equation in Part 9 for ma ximum tee stem thickness. in 16 1 2 d tb max s (Eq. 5.1) db = bolt diameter (in.) The tables for extended tees do not check th is requirement for ductility. There is the possibility that because of the extended stem length that this requirement is not applicable. 5.2.2 Extended Tee Equation In order to have a more general solution than the one presented by the extended tee tables, Equation 5.1 has been formulated to determine the design capacity of an extended tee connection. The limit states for an exte nded tee connection alwa ys involve the bolts connecting the tee to the supported member. Therefore, a similar approach to the Ccoefficients given in Chapter 7 in the AISC Manual (2001) has been developed. The formulation involved plotting the IC coefficients for each bolt group (from 2 bolts to 12 bolts). The plots for each group were than curve-fit to determine a general relationship.

Usi ng the parametric bay study to determine the highest practical shear reaction, the number of curves was reduced from 11 to 7. The excluded curves include those using 9 bolts or above, therefore; the retained curves include only those using be tween 2 and 8 bolts. The re tained curves were bounded between an eccentricity of 5 a nd 16 inches because this was deemed the practical range for extended connections. The reduced set of curves was fit with l ogarithmic curves and from that a general equation was derived: 2 x 1C e ln C IC (Eq. 5.2) Where: IC = instant center coefficient

51 CHAPTER 7 FINITE ELEMENT ANALYSIS 7.1 Introduction This chapter presents the results of a finite element study that was conducted on a single angle bolted connection where the protruded leg of the angle extended beyond the flange of the supporting girder The behavior of the exte nded connection was compared to that of a standard equal leg angle connect ion that would be used in a coped beam to girder connection. The finite element m odel consisted of three main parts: the connection angle, bolts and a portion of the supporting girder web. Each of these parts was modeled with three-dimensional (3D) solid elements. Additionally, the contact surface between connected elements, e.g. angle and girder web were modeled. The finite element model incorporat ed the effects of material and geometric nonlinearity as well as including the effect of initial bolt pr etension on the overall connection behavior. The finite element analysis was carried out using the latest commercially available ADINA finite element software package, Version 8.1 (ADINA 2003). This finite element package has the capability to m odel complex phenomena such as contact problems, initial stresses, non-linear material and geometric behavi or as well as dynamic analysis. The user inputs the geometry as a 3D model drawn in a Computer Aided Design (CAD) environment. Then, after spec ifying the desired type of element(s) and mesh density, the program automatically ge nerates an optimal finite element mesh. Once the analytical model is generated th e analysis results can be presented in numerous graphs and plots show ing critical behaviors that are identified such as the

PAGE 63

52 applied load-vertical tip displacement beha vior and the effectiv e stresses occurring throughout the model. The basic finite elem ent model was created where the position of the bolt line in the in-plane angle leg corresponded to th at of a standard coped beam to girder connection. The finite element m odel was then modified by adding additional elements to the in-plane angle leg to account for the bolt line being located further away from the girder web. This model represen ted the protruded angl e leg of an extended connection where the supported beam would not need to be coped prior to being connected to the supporting girder. The materi al strengths used in the models for the structural shapes consisted of both A36 and A572 Gr. 50 steel. Therefore, the material steel strength was considered a model parameter. The finite element analysis results for the various models are compared as well as to the current design procedures that are in the AISC Manual of Steel Construction (AISC 2001). 7.2 Finite Element Model Development 7.2.1 FE Discretization for Angle Three-dimensional (3D) solid elements were utilized to model the angle section. These elements are 8-node elements as described in the ADINA Theory and Modeling Guide (ADINA 2003). Each node in the soli d element has three master degrees of freedom: X-translation, Y-tran slation, and Z-translation. The basic finite element mesh for the angle contained 5830 solid elements and 6320 nodes. The angle mesh detail is shown in Figure 7.1. The angle section used in the basic model represented a L3 x 3 x 5/16 and was 9 inches long. This length was chosen since it is representative of a standard three-bolt shear conne ction with 1 in. edge spac ing and 3 in. center-to-center spacing of the bolts. The 3 inch protrude d leg in the basic model was extended to 5 inches in the modified finite element model.

PAGE 64

53 The basic and modified models were de veloped for a three-bolt connection. A standard bolt hole diameter was used in each of the models and consisted of holes that had a 0.8125 inch diameter fo r inch diameter bolts. Following a convergence study of the contac t problem between the bolts and the bolt holes, it was determined that four elemen ts would be necessary through the thickness of the angle leg (Wheeler et al. 2000). Si nce there were no bolt holes modeled in the protruded leg, only two elements were used through the thickne ss in order to decrease the number of elements used in the finite elem ent mesh of the angle (Mao et al. 2001). A convergence study was also carried out to determine the required element size to be used to model the angle section. Three mesh sizes a coarse, fine, and extra fine mesh were created with average element si zes of 0.4, 0.3, and 0.2 inches, respectively, along the top and bottom edges of the angle. It was de termined, from the convergence study, that it would be necessary to use the extra fine mesh in modeling the angle section. Therefore, with this mesh size thirty elements were generated around the circumference of each of the bolt holes. 7.2.2 FE Discretization for Girder Modeling of the supporting girder was simp lified to that of modeling its web in order to decrease the number elements used in the overall finite element model. Threedimensional (3D) solid elements were utilized to model the web of the girder, the same type of elements used to mode l the angle section. The basic finite element mesh for the girder web contained 5296 solid elemen ts and 5834 nodes. The girder web was constructed as a plate with a width of 5 in ches, height of 11 inch es and a thickness of 5/16 inches. The mesh detail is shown in Figure 7.1.

PAGE 65

54 Three bolt holes were modeled in the web of girder to corre spond with the three bolt holes in the angle. The diameter of these bolt holes was also 0.8125 inches. Following the same convergence study of the contact problem between the bolts and the bolt holes, it was determined that four elemen ts would be required through the thickness of the girder web. Similar to the angle mesh convergence st udy, three different element sizes were considered for the girder web mesh. The av erage element sizes that were evaluated had dimensions of 0.4, 0.3 and 0.25 inches. Base d on the results of th e study, the 0.25 inch element size was chosen for the girder web me sh. Also, in order to match the mesh of the angle section that was connected to the web of the girder, thirty elements were generated around the circumferen ce of each of the bolt holes. 7.2.3 FE Discretization for Bolts High strength structur al ASTM A325 and A490 bolts we re included as part of the finite element model. The two types of bolts were each modeled in a similar fashion, the only difference being their materi al behavior. Depending on th e type of bolt used in the model, a minimum pretension c ould be applied to the bolt in accordance with the AISCLRFD Specification (AISC 1999). Three-dimensional (3D) solid elements were utilized to model each of the three bolts. These elem ents were 8-node elements as described in the ADINA Theory and Modeling Guide (ADI NA 2003) with three master displacement degrees of freedom per node. The basic finite element mesh for the three bolts included 10251 elements and 11685 nodes. The bolt me sh detail is shown in Figure 7.1. The diameter of each bolt that was modele d was inch while the diameter of each bolt head was 1 inch. In addition to the bolt and the bolt head being modeled, the nut was also included as part of the finite el ement model. Along the body of the bolt, eight

PAGE 66

55 elements were modeled in order to match th e four elements thr ough the thickness of the angle leg and the other four elements through the thickness of the girder web. Four elements were generated through the thickness of the bolt head and the nut. In order to match the angle and girder web mesh, thirty elements were cons tructed around the body of the bolt, the bolt head and the nut. 7.3 FE Model Contact Conditions A contact condition can be specified in ADINA to model the contact behavior between solid elements and other structural elem ents such as the truss, beam, shell, plate and pile elements. Since only 3D solid elemen ts were utilized in the model, the contact group that was used in the model was the 3D cont act group. In this ty pe of contact group, one of the two contact surfaces that formed is called the contactor su rface and the other is called the target surface. Duri ng the loading of the finite element model the two contact surfaces are expected to come into contact and become a contact pair. All parts of the bolted-bolted shear conn ection are connected to each other through the contact condition. When the applied load fr om the beam is imparted to the angle, the angle begins to displace which then causes it to come into contact with the bolts. The displacement of the outstanding leg of the angle in turn then causes the bolts to come into contact with the girder. When the bolts are also pretensione d, the bolt heads are brought into contact with the in -plane leg of the angle, the nuts are brought into contact with the girder web and the facing elements of the in-plane angle leg and the girder web are brought into contact prio r to the load being a pplied to the model. The contact surfaces as described above were defined as surfaces that were initially in contact or were anticipated to come into contact by the pretensi oning of the bolts or during the application of the lo ad. In order to avoid an ove rconstrained analysis problem

56 that is caused when a contactor node belongs to more than one contact surface in a contact group, a total of 36 surfaces, divided to 8 contact groups, and 20 contact pairs were constructed as part of the overall fini te element model. These contact groups and contact conditions are described in Tables 7.1 and 7.2 as follows: Table 7.1-Finite Element Model Contact Group Descriptions Contact Group No. Contact Description 1 Contact surface between the in-pla ne angle leg and the girder web(a) 2 Contact surface between the bolt he ads and the in-plane angle leg 3 Contact surface between th e nuts and the girder web 4 Contact surface between the shank of the bolts and the holes in the inplane leg of the angle(a) 5 Contact surface between the shank of the bolts and the holes in the web of the girder(c) 6 Contact surface between the in-pla ne angle leg and the girder web 7 Contact surface between the shank of the bolts and the holes in the inplane leg of angle(b) 8 Contact surface between the shank of the bolts and the holes in the web of the girder(b) Notes: (a)The contact surface between the in-plane leg and the girder web was divided into group numbers 1 and 6 (b)Contact surface between the sh ank of the bolts and the hol es in the in-plane leg of the angle was divided into group numbers 4 and 7 (c)Contact surface between the sh ank of the bolts and the holes in the web of the girder was divided into group numbers 5 and 8

58 Tables 7.1 and 7.2 describe the detailed interactions that occurred in the finite element analysis. Table 7.1 gi ves the general description of the eight contact groups that were included in the model. Table 7.2 gives the detailed interactions between the three main components that were included in the model and are called Bodies. The girder web included two Bodies that were numbered 3 and 6. The angle include d five Bodies that were numbered 1, 2, 4, 5 and 10. The bolts included three Bodies that corresponded to the three bolts that numbered 7, 8 and 9. If no contact pair number s given in the table that means that these two surfaces did not come into contact during the analysis. ADINA has a library of simple Bodies contained within ADI NA-M that can be specified for contact problems. If the Body is of a complex nature it needs to be modeled by the user. In the bolted-bolted beam-to-gird er finite element model that was created only Body numbers 1 and 3 were taken fr om the ADINA-M library. The other Body numbers were more complex and had to be developed from the simple Body definitions provided in the software. For these re maining complex Bodies, ADINA assigned Face numbers to each Body (e.g. the simple block Body has six Faces that are assigned Face numbers 1 through 6). ADINA automatically assigned Face numbers to each complex Body that was modeled such as the bolt shanks or the in-plane leg of the angle having three bolt holes. Only th rough direct observation of th e graphical ADINA output could the automatically assigned Face numbers be identified. An important distinction betw een a contactor surface and a target surface is that in the converged finite element so lution, the material overlap at the contactor nodes is zero while the target nodes can overlap the c ontactor body (Bathe and Chaudhary 2000). Therefore, the surfaces in the angle holes we re formed as a contactor surface while the

PAGE 70

59 surfaces on the bolts that are in contact with the angle holes were formed as the target surface. On the other hand, th e surfaces on the bolts that are in contact with the girder web were assigned as the contactor surfaces wh ile the surfaces in the girder web holes were denoted as the target surface. The model of the connection with pretensi oned bolts meant that there was friction between the in-plane leg of angle and the gi rder web. This friction along the contact surface was handled in the model by assigni ng a compression force that acts on each contactor node and that node is allowed to kinematically s lide along the target segments generating a tangential force that is equal to the Coulomb fricti on force (ADINA 2003). In ADINA, the user only has to input a C oulomb friction coefficient in the model definition of the contact group where it is to be considered and then the program automatically determines the tangential force from the compression force based on the following equation: n tT T (Eq. 7.1) Where: Tt = Tangential force Tn = Normal force = Coulomb friction coefficient In the finite element model that was crea ted only the friction between the in-plane leg of angle and the girder web was consider ed. The Coulomb friction coefficient that was assumed for this frictional contact was = 0.2. The frictiona l contact between the bolt heads to the in-plane angle leg as well as the nuts to the girder web was not considered. This modeling assumption was made since these contact surfaces had a

PAGE 71

60 much smaller surface area than that of the in -plane angle leg being in contact with the girder web. This assumption also helped to decrease the analysis run time and the number of iterations that necessary for each time step to converge. 7.4 FE Model Initial Conditions The three-bolt connection was pretensioned to assure that the le g of the angle was brought into firm contact with th e web of the girder before the vertical load was applied. In order to accomplish this in the finite elemen t model, an initial stress was applied to the bolts to create the pretension. Follo wing the ADINA-Theory and Modeling Guide (ADINA 2003), the initial stre ss could be done by three di fferent methods: nodal initial strain, element initial strain or directly applying a pressure lo ad. The direct pressure load application method was selected because it was easy to apply and the magnitude of the specified pressure load could be changed. Furthermore, the method accurately reflected the behavior of the bolts when they are pr etensioned, i.e. only the body of the bolt had a pretension load, not the bolt heads or nuts. In order to generate the bolt pretension, a pressure load was simultaneously applied at each bolt head and nut. The pressure load th at was applied to the inch diameter bolts in the finite element model was 10 ksi. This initial condition was established in the first step of the analysis. After that, in the second step, the pretension load was omitted and the external vertical load was incrementally applied. 7.5 FE Model Applied Loading A static analysis solution scheme wa s performed using ADINA on the finite element model. This type of solution does not include time depende nt effects, so the specified time step increment in the progr am was used to define the increment or intensity of each load step incr ement. In order to ensure convergence was achieved in the

PAGE 72

61 solution, the number of time steps needed to be small and it was typical for the analysis runs to use more than 350 time steps in each case. The finite element model loading was car ried out in two steps: Step 1 was described in Section 7.4 where a pretension load was generated in the bolts, and Step 2 is described in this section where the external ve rtical load was applied to the model. The vertical shear load was a pplied incrementally from zer o until a maximum value was reached. This maximum load indicated that the bolted-bolted connection had reached its ultimate load-carrying capacity. The vertical shear load was transmitted fr om the beam into the connection angle through the three bolts attaching it to the protruded leg. Th ese three bolts were modeled as three load groups and each group consisted of six single loads as shown in Figure 7.2. The locations of where the vertical loads we re applied were determined from the usual geometry of where the bolt holes would have been if they had been modeled. These locations in the protruded leg were at a horiz ontal distance of 2 inches from the heel of the 3 inch angle leg and 3 inches fr om the heel of the 5 inch angle leg. 7.6 FE Model Boundary Conditions There were two types of boundary conditions ut ilized in the model. The first type of boundary condition was placed on the vertical edges of the girder we b. Recall that its model definition consisted of 8-node, 3D solid elements with three master degrees of freedom at each node (X-, Yand Z-transla tion). To simulate a fixed type boundary condition, all the nodal translational degrees of freedom were fixed along these edges which were away from the portion of the web where the angle was attached. This boundary condition was generated along the two edge s of the girder web that are parallel to the Z-axis as shown in Figure 7.3.

PAGE 73

62 The second boundary condition was placed on th e protruded angle leg. In a real bolted-bolted connection this pr otruded leg would be connected to the web of a beam, but since this web was not modeled, a boundary co ndition was imposed to simulate this part of the connection. The inhere nt stiffness in the connection between the web of the beam and the protruded angle leg woul d restrain this part of the connection from twisting or moving in the X-direction. Th erefore, the X-direction move ment of the angle was fixed through the use of a boundary condition imposed on every node that made up the exterior face of the protruded angle leg. This bounda ry condition can be seen in Figure 7.3. 7.7 FE Model Material Behavior The inelastic material behavior of the angl e, girder web and bolts were considered in the finite element model development. Two steel material types, A36 (ASTM 2003?) and A572 Gr. 50 (ASTM 2003?) were assigned to the angle while only one type of steel material, A572 Gr. 50 was assigned to the gi rder web. Again, there were two steel material types assigned to the bolts – either A325 (ASTM 2003?) or A490 (ASTM 2003?). No material coupon tests or bolt test s were conducted for th is project so it was decided that a reasonable way to incorporate the inelastic behavior of the steel materials was to treat each type as having a bi-lin ear stress-strain curve (Salmon and Johnson 1996). Regardless of the type of steel materi al, the Modulus of Elas ticity, E, was defined as having a value of 29,000 ksi. The stressstrain relationships provided in the ADINA FE models for the A36 steel, A572 Gr. 50 st eel, A325 bolt steel a nd A490 bolt steel are given in Figures 7.4 through7.7. All of the ma terial bi-linear curves are comprised of two straight line segments. The first portion represents the el astic behavior and goes from zero to a point defined by th e yield strain and the corresponding yield stress of the material, ( y y). The second portion represents the inelastic behavior of the material.

PAGE 74

63 This part of the stress-strain curve starts at ( y y) and is terminated at a point defined by the ultimate strain and the corresponding ultimate tensile st rength of the material, ( u u). It was felt that this leve l of strain would not be exceeded in any of the analyses so the stress-strain curves did not need to be extended any further than that provided. Table 7.3 FE Model Steel Material Properties ASTM Designation Yield Stress, y (ksi) Ultimate Tensile Strength, u (ksi) A36 36 58 A572 Gr. 50 50 65 A325 80 100 A490 100 120 Finally, the steel materials for the angle a nd girder web along w ith the different bolt types were arranged into groups and analyzed as shown in the Table 7.4. Table 7.4 FE Model Material Groups Angle Girder Web Bolt Group I A36 A572 A490 Group II A36 A572 A325 Group III A572 A572 A490 7.8 FE Analysis Results The results from each FE model were post-processed through ADINA-Plot, a branch of the ADINA finite element softwa re package, Version 8.1 (ADINA 2003). In order to compare the analysis results from different model configurations a consistent approach to the data would need to be taken. It was decided that th e best way to do this would be to either: 1) Plot the incremental applied load versus the tip deflection of the protruded angle leg from differe nt FE models; or 2) Plot the incremental applied load versus the end rotation of the protruded angl e leg from different FE models. The end rotation of the leg was calculated from the displacement results taken at two nodes on the

PAGE 75

64 toe of the protruded leg. The first node was located at the top corner and the second node was located at the bottom corner of the prot ruded leg. The node numbers from the two different geometric models that were used to determine the end rota tion of the angle leg are shown in the Table 7.5. Table 7.5 Corner Node Numbering Model Description Top Corner Node Bottom Corner Node 3 in. Protruded Leg Model 24703 22556 5 in. Protruded Leg Model 27719 22591 The end rotation, of the protruded leg from each analysis result was calculated using the following the equation: top bottom bottom topZ Z in 9 Y Y (Eq. 7.2) Where: Ytop = Displacement of the top corner node in the Y-axis Ybottom = Displacement of the bottom corner node in the Y-axis Ztop = Displacement of the top corner node in the Z-axis Zbottom = Displacement of the bottom corner node in the Z-axis 9 in. = Length of the angle It was necessary to take into account both th e Y-axis displacement as well as the Z-axis displacement in the calculation of end rota tion since the protrude d angle leg did not deform solely in its own plane. Figure 7.8 shows the load vs. displacement results of the Material Group I finite element model with a 5 inch protruded leg where the maximum displacements reached 0.36 and 0.23 inches in the Yand Z-axis, respectively when the maximum applied load reached 34.8 kips. This occurred at time step = 193.

PAGE 76

65 The applied load vs. end rotation was co mpared for two Material Group I models that only differed in the length of the prot ruded angle leg (see Fi gure 7.9). The model with the 3 inch protruded leg converged at time step = 277, corresponding to a maximum applied load of 49.9 kips and an e nd rotation of 0.054 rad. The model with the 5 inch protruded leg converged at time st ep = 193, corresponding to a maximum applied load of 34.8 kips and an end rotation of 0.053 rad. The next applied load vs. end rotation comparison that was made evaluated the results from the Material Group I (A490 bolts ) and II (A325 bolts) mode ls. The length of the protruded angle leg in each model was 5 inches. The model with the A325 bolts reached a convergence limit when time step = 194, corresponding to a maximum applied load of 35.0 kips and an end rotation of 0. 058 rad. In comparison, the model with the A490 bolts converged at time step = 193, co rresponding to a maximum applied load of 34.8 kips and an end rotation of 0.053 rad. The results of this comparison are shown in Figure 7.10. The last applied load vs. end rotation comparison that was made evaluated the results from the Material Group I (A36 angl e) and III (A572 Gr. 50 angle) models. The length of the protruded angle leg in each model was 5 inches. The model with the A36 steel angle reached a conve rgence limit when time step = 193, corresponding to a maximum applied load of 34.8 kips and an e nd rotation of 0.053 rad. In comparison, the model with the A572 Gr. 50 stee l angle converged at time step = 240, corresponding to a maximum applied load of 43.2 kips and an e nd rotation of 0.066 rad. Figure 7.11 shows the comparison between these two analysis results.

PAGE 77

66 Figures 7.12 and 7.13 are smoothed effec tive stress plots showing the change in model behavior from the initial time step to the final time step, respectively of the analysis run with Material Gr oup I and a 3 inch protruded angle leg. At time step = 1.000 there was no externally applied load, only the pretension in the bolts. The maximum smoothed effective stress was appr oximately 14 ksi and that was fairly uniform between the angle, girder web and th e bolts. At time step = 193, the maximum smoothed effective stresses were 65.78 ksi in the angle, 88.14 ksi in the girder web and 132.6 ksi on the bolt shank. The critical stre ss occurred at the locati on of the top hole in the angle leg. This would correspond to reac hing a limit state of bolt bearing on the angle material which is the same limit state that would have been found if using the design tables in the Appendices. Figures 7.14 and 7.15 show the maximu m smoothed effective stress plots for analysis runs with Material Groups II and III, respectively and a 3 inch protruded angle leg. For Material Group II (time step = 194) these stresses were 70. 05 ksi in the angle, 88.11 in the girder web and 98.30 ksi on the bolt shank. For Material Group III (time step = 240) these stresses were 78.91 ksi in the angle, 99.95 ksi in the girder web and 136.8 ksi on the bolt shank. In each case the maximum stress occurred at one of the bolt hole locations indicating that a limit state of bolt bearing was reached. One more comparison was made between all the models previously discussed and a new model where the boundary condition along th e vertical edges of the girder web was changed from being fixed to that of being pi nned. Figure 7.16 show s the applied load vs. end rotation behavior of the new model compared to all the previous results. The pinned boundary condition has a marked influence on th e rotational behavior of the connection

PAGE 78

67 whereas the strength of the connection only changed sligh tly. A convergence limit was reached in the analysis of th is model at time step = 207, co rresponding to an applied load of 37.2 kips and a maximum end rotation of 0.129 rad. Again, the maximum stresses occurred at the top bolt hole location, but now it was bolt bearing on the girder web.

80 CHAPTER 8 SUMMARY AND CONCLUSIONS Extended all-bolted double angle, single a ngle, and tee connections are a viable alternative to standard shear connections with coped beam s. The connections have a limited range of applicability, but in low-rise commercial buildings with lightly loaded bays, an extended connection will be econom ical. The connections require no new construction methods or mate rial, so they can be put to use immediately. The introduction of longer leg or higher yield stre ngth will increase the range where extended all-bolted connections can be used. The tables located in the appendices of th is document are considered reliable for design use. The methods that are used to tabulate them ar e all based on sound theory and mechanics. It is recommended that before extended all-bolted conn ections are introduced into common practice that some confirmato ry laboratory testing be conducted. The results from this testing may require modi fications to the assumptions made in the calculation of the design tables. Also, more testing is recommended in th e area of beam-to-girder connections. Almost all previous research is oriented towards beam-to-column connections. The behavior of a beam-to-girder connection will al most certainly vary somewhat from that of a beam-to-column connection. Beam-to-girder connections are usually made to the web of the girder and the web of the beam wh ile beam-to column connections connect the column flange to the beam girder. The stiffnesses between the girder web and the column flange vary. This may affect the overall connection behavior This insight may

PAGE 92

81 help with the design of extended connections Also, the differences between two-sided connections as with interior girders where th ere is one connection on either side of the girder web, and one-sided connections to sp andrel girders should be considered during the testing of beam-to-girder connections. The design of extended all-bol ted double angle, single an gle, and tee connections must be carefully considered. The designer should understand the theory and mechanics that are involved in the design of these conn ections. The tables located in the appendices section are only tools and de signers should use their best judgment when selecting the type of connection to be specified..

406 APPENDIX O 1-INCH DIAMETER ALL-BOLTED A992 STEEL TEE CONNECTIONS The tables given in Appendi x O are all-bolted tee connect ions. The tees are A992 tees using either A325/F1852 or A490 1-inch diameter bolts. The edge distance, Leh, is assumed to be 1.25 inches. Tees with a stem thickness less than the limiting thickness use the first row for the appropriate connection type. The value given in the first row is in units of kips per inch of stem thickne ss. The design capacity is the stem thickness times the value given. Tees with a stem thickness greater than the limiting thickness use the second row for the appropriate connection ty pe. The value given in the second row is in units of kips. The design capacity is the value given. Does not meet the ductility requireme nts of Part 9 in the AISC Manual.
