A Survey of SDS/2 Connections
A Survey of SDS/2 Connections This is a survey of some of the many connections that SDS/2 can design. The pictures were selected to give you a feeling for the range of connections that are available to you when you use SDS/2. All of the information in this survey can also be found in the SDS/2 context-sensitive help manual that comes with the program.

Connections Applied on Beams: Bend Plates
A Survey of SDS/2 Connections
Connections Applied on Beams: Bent Plates ---- SDS/2 is able to design bent plates on the end of a wide flange or S shape or welded plate wide flange or channel beams under beam-to-beam or beam-tocolumn framing conditions. ---- The supported beam can be skewed or sloped or framed perpendicular to a wide flange or S shape or welded plate wide flange or tube column, but not a pipe column. ---- Bent plates may optionally be detailed with (shop attached to) the supporting or supported member. ---- If framing to a tube column, the bent plate must be shop welded to the column. ---- Bent plates are often applied in skewed framing situations. SDS/2 can design bent plates from 56 to 90 degrees for two-sided connections and from 18 to 90 degrees for one-sided connections.
Bent plates welded to the supported This example shows skewed beam-to-beam framing from beneath the top flanges of the beams. Web doublers are designed on the supported beam to prevent web buckling. * **

A bent plate can be designed on the near side or far side (or both sides) of the supported beam's web. 3
A Survey of SDS/2 Connections
Connection Applied on Beams: Clip Angles
Connections Applied on Beams: Clip Angles ---- SDS/2 can design clip angles on the end of a W or S or welded plate W or C or tube beam in beam-to-beam or beam-to-column framing situations. ---- The supported beam can be sloped or perpendicular to a wide flange or S shape or tube or welded wide flange or welded plate box column, but not to a pipe column. ---- If an SDS/2 user specifies a clip angle that welds/bolts to a pipe column or bolts to a tube or welded plate box column, SDS/2 will change the clip angle to a singleplate shear connection. ---- If the beam frames to a tube or welded plate box column, the clip angle must be shop welded to the supporting column. ---- Clip angle connections are applied on the end of the supported beam. They may optionally be detailed on (shop attached to) the supporting member (column or beam). ---- Moment options can be applied to a W or S beam with a clip angle connection that frames to a W or S or welded plate W column web or flange or to a tube column. ---- During Process and Create Solids , connection design looks to relevant setup options, the framing situation and clip angle connection settings to design an initial minimum setup connection. To then design a connection that stands up to the "Shear load " on the supported beam, connection design may increase bolt diameters, weld size, number of rows of bolts, or create web doublers.
Clip angles for beam-to-beam offset framing * **
***
* or 'Auto Standard ' ** or 'Narrow ' gage *** or 'Supporting '
For offset beams framing to opposite sides of a supporting beam web, SDS/2 automatically selects an angle that will carry the standard gage from the " Angles" list in Standard Fabricator Connections . If no angle is found, the connection may be changed to a shear plate connection.

Connections Applied on Beams: Clip Angles
Clip angles on a sloping beam to a beam flange * **
*** * or 'Auto Standard ' ** or 'Narrow ' gage *** or 'Supporting '
SDS/2 can design clip angles on the end of a beam that slopes perpendicular (not skewed) to a beam flange. This can be done for wide flange, S shape, welded plate W or channel beams.
Clip angles on a sloping beam to a column
* **
* or 'Auto Standard ' ** or 'Narrow ' gage
SDS/2 can design clip angles on the end of a beam that slopes to a supporting column flange (as shown) or to a column web.
Clip angles bolted to both members * **
* or 'Auto Standard ' ** or 'Narrow ' gage

Connections Applied on Beams: Clip Angles
Bolted clip angles with staggered bolts * **
* or 'Auto Standard ' ** or 'Narrow ' gage
Clip angles with beam web doublers * **
* or 'Auto Standard '
** or 'Narrow ' gage
Depending on the shear load on the beam, SDS/2 designs a single web doubler that is 3/16 inch thick on one side of the supported beam's web, or two web doublers (one on each side of the web). If web doublers are not needed to prevent web buckling, then no web doublers are designed. For welded-tosupported clip angles, SDS/2 welds the web doublers.
Heavy gage clip angles as beam splices *
* or 'Auto Standard '
Heavy gage clip angles have two columns of bolts. You can also get beam splices using ' Narrow' or 'Wide' gage clip angles on wide flange, welded plate wide flange, S shape or channel or tube beams. 6

Safety clip angles * **
* or 'Auto Standard ' ** or 'Narrow ' gage
Safety clip angles can be designed when two beams with clip angles frame on opposite sides of a supporting beam or column web.
Bottom flange cut for safety clip angle * **
* or 'Auto Standard ' ** or 'Narrow ' gage
For SDS/2 to design this connection, the box must be checked for " Extend connection and cut flange flush" in Clip Angle Setup .
Clip angle with expanded vertical bolt spacing
If "Tension" or "Compression" is applied to a supported beam and ' Yes' is selected for " Expand bolt spacing ," SDS/2 expands the spacing either 1.5 or 2 times the " Normal hole spacing " in Fabricator Options . 8
A Survey of SDS/2 Connections
Connections Applied on Beams: Clip Angles
Clip angle with extended welded tee
SDS/2 can design the built-up tee to be the length of the clip angle only if the top & bottom flanges of the supported beam are entirely below or entirely above (as shown) the half-depth of the supporting beam.
Clip angle with full depth welded tee
This applies to a wide flange or welded plate W or S shape or channel beam to a W or S or welded plate beam. SDS/2 designs the built-up tee to be the full depth of the supporting beam if the depth of the supported beam is greater than 1/2 the depth of the supporting beam.
Clip angle extended past flange extended clip angle *
flange cut flush to web * or 'Auto Standard '
SDS/2 extends the clip angle past the flange when the "Shear load " is sufficiently large only when 'If required ' is selected for " Extend past flange."

Clip angle extended past flange of sloping beam
If If ' required ' had not been selected for " Extend past flange" in this situation, SDS/2 would have failed this connection, resulting in a ' Plain end ' on the beam.
Clip angle with safety erection seat
Safety erection seats may be applied to wide flange beams with 'Non-moment ' clip angle connections. You have the option to have the seat designed on the top or bottom flange of the beam.
Clip angle moment connection
" Moment Specifications " can be added to clip angles on beams framing to a column flange or web. See page 22 for more on moment connections.

A Survey of SDS/2 Connections
Connections Applied on Beams: End Plates
Connections Applied on Beams: End Plates ---- You can apply non-moment end plates on the end of a W or S or welded plate W or C or tube beam under beam-to-beam or beam-to-column or beam splice framing conditions. A non-moment end plate can frame to a wide flange or S shape or welded plate wide flange or tube column or beam, but not to a pipe member. ---- AISC type moment end plates can only be applied on W or S beams. For SDS/2 to design an end plate beam splice (non moment), the beams must be colinear W or S sections with top flanges that are no more than one inch apart in end elevation. ---- For moment end plate splices, the beams must be colinear W or S sections of the same size whose top flanges are at the same elevation. End plates are detailed with (shop welded to) the beam they are applied on. ---- Non-moment end plates may be applied under skewed framing conditions. 45 degrees is the general limit, but the actual limit depends on the beam size and framing situation. ---- Moment options only apply to non-skewed or non-sloping end plate connections. ---- During Process and Create Solids , SDS/2 checks the " Flats" list of available bar stock material. If appropriate flat bar material is found, SDS/2 uses the flat bar and takes into account the rolled edge when setting the horizontal edge distance. If no appropriate flat bar material is found, SDS/2 uses plate material.
Non-moment end plate *
**
* or 'Auto Standard ' ** or 'Narrow ' gage
Non-moment end plates may be applied on a beam framing perpendicular, sloped or skewed to a beam or column.
Moment end plate

Non-moment end plate with expanded bolt spacing
*
* or 'Narrow ' gage
If "Tension" or "Compression " is applied to the supported beam and 'Yes' is selected for " Expand bolt spacing ," SDS/2 expands the spacing either 1.5 or 2 times the " Normal hole spacing " in Connection Detailing and Fabrication Options . 12
A Survey of SDS/2 Connections

* * or 'Narrow ' gage ** 'Top ' is the other option
**
Safety erection seats may be applied to wide flange or S shape or welded plate wide flange beams with ' Non-moment ' end plate connections framing perpendicular to the supporting member.
End plate beam splice (moment splice shown)
The beams must be colinear W or S sections. For moment splices (like that shown), the sections must be the same size and the top flanges at the same elevation.

Connections Applied on Beams: Shear Connections
A Survey of SDS/2 Connections
Connections Applied on Beams: Shear ---- Shear connections may be applied on the end of a W or welded plate W or C or tube beam under beam-to-beam or beam-to-column framing situations. They are detailed on (welded in the shop to) the supporting column or beam. ---- Shear thru connections may frame to tube or pipe columns. ---- Single-plate shear connections may frame to wide flange, tube, pipe, welded wide flange or welded plate box columns. ---- Shear tee connections may frame to wide flange or tube columns, but must be shop welded if framing to a tube column. ---- Shear connections may be used in skewed framing situations. SDS/2 can generate a shear plate from 20 to 90 degrees. Moment flange plates can be applied to beams with skewed or perpendicular shear plates and slopes up to 30 degrees from horizontal. ---- During Process and Create Solids , connection design looks to relevant setup options and shear connection specifications to design an initial setup connection. To then design a connection that stands up to the " Shear load " on the supported beam, connection design first increases rows of bolts, then bolt diameter and last plate thickness.
Shear plate extended to brace gusset
This type of connection can be designed when a vertical brace frames to a beam and column.

Connections Applied on Beams: Seats
A Survey of SDS/2 Connections
Connections Applied on Beams: Seats ---- Beam seats are applied in SDS/2 on the ends of beams, but are detailed on (shop welded or bolted to) columns. A bolted stability angle may be designed with the beam seat and optionally detailed on the beam or on the column. Welded stability angles are not designed and do not appear on details, but are assumed to be shipped loose. ---- SDS/2 can automatically design a seat for a W or S or welded plate W or C or tube beam framing to the flange or web of a W or S or welded plate W or tube column, but not to a pipe column. WT, L or plate may be used as the seat material. Sloping plate seats can be designed for beams that slope up to 30 degrees from horizontal. ---- During Process and Create Solids , SDS/2 looks to relevant Job/Fabricator Options, beam seat input settings (on the Beam Edit window or in Auto Standard Connections ) and the "Shear load " on the supported beam to design the beam seat.
Plate beam seat *
* or 'Auto standard '
SDS/2 can automatically design a seat for a W or C or tube (HSS rectangular) beam framing perpendicular to a wide flange or tube column.

Connections Applied on Beams: Splices
A Survey of SDS/2 Connections
Connections Applied on Beams: Splices ---- Some splice connections (for example, splice plates) cannot be applied as auto standard. This is because auto standard connections provide no way to determine which member is the supported member, and therefore there is no simple way to define for SDS/2 on which beam to shop attach the splice plates. ---- SDS/2 can design non-moment splice plates on wide flange, S shape, welded plate wide flange or channel beams. Both beams must have the same " Web rotation." The beams can slope at different angles, but cannot be skewed with respect to one another. ---- For moment splices, both beams must use W or S " Section sizes" with depths that are less than 1 1/4 inches in difference, and the work lines of the beams must be colinear.
Non-moment beam splice plates
* * or 'Other member '
The beams must be W or S or welded plate W or C sections with the same " Web rotation." SDS/2 designs splice plates on both sides of the beam web.
Moment beam splice plates
* or 'Other member '
*
The beams must be colinear and use W or S "Section sizes" with depths that are less than 1 1/4 inches in difference.
Splice plates for beams at different slopes
*
* or 'Other member '
If there is a slight difference between the slopes of the two beams, you have a setup option (in Member Detailing/Fabrication Options ) to "Square cut " the beams. 20

Clip angles as beam splices *
* or 'Auto Standard '
This example shows heavy gage clip angles (which have two columns of bolts). You can also get beam splices using 'Narrow' or 'Wide' gage clip angles on wide flange or channel beams. The clip angles must field bolt to one another.
Non-moment end plate beam splice
* * or 'Narrow ' gage
The beams must be colinear W or S sections with top flanges no more than one inch difference in end elevation.
Moment end plate beam splice (AISC type shown)
The beams must be colinear W or S sections. For moment splices (like that shown), the sections must be the same size and the top flanges at the same elevation. ' MBMA' type moment end plates can also be designed. 21
Applied on Beams: Moment Connections
A Survey of SDS/2 Connections
Applied on Beams: Moment Connections ---- Moment connections can be applied on wide flange or S shape beams framing to other W or S beams or to wide flange, welded plate wide flange, tube or pipe columns. MBMA end plate connections can also be applied to welded plate wide flange beams. ---- To set up moment connections: In Job Options, see Moment Plate Design Criteria and Moment Connection Flange Plate Gaps, Weld Design Criteria and Seismic Weld Access Holes Configurations. ---- Moment connections can be designed when the " Input connection type" is 'Clip angle' or 'Shear ' or 'End plate' or 'Splice plate .'
Clip angle moment connection with flange angles
This connection requires the framing situation of a W or S beam perpendicular to a W or S or welded plate W column flange or to a tube column. A suitable angle must be in the " Angles" list in Standard Fabricator Connections . If a suitable angle is not found, SDS/2 will design a moment connection with flange plates instead of failing the connection.
Clip angle moment connection with flange plates
Connections similar to this can be designed when a W or S beam frames perpendicular or sloping to a W or S or welded plate W column flange or to a tube column. You can change the " Input connection type " to 'Shear ' and still get a moment connection. 22

Connections Applied on Columns
Connections Applied on Columns ---- The types of connections that can be applied to columns are ' Auto base/cap plates,' 'User base/cap plates ,' and 'Splice plate' connections. These connections can be applied as ' Auto standard ' as well as entered directly as the " Input connection type " on the Column Edit window. ---- An ' Auto base/cap plate' and 'User base cap plate ' can be designed on a W, S, welded plate W, pipe or tube or welded plate box column. An ' Auto base/cap plate' requires that the column frame to a beam or joist unless it is a ' User defined ' or 'Forced ' connection. No such framing condition is required for a ' User base/cap plate .' ---- Selecting 'Splice plate' as the " Input connection type " permits you to specify three different types of splice connections: 1) Bolted splice plates, which can only be applied to W, S or welded plate W columns. 2) Welded splices, which can, in addition, be applied to pipe, tube and welded plate box columns. 3) Welded splices with channel web connections, which can only be applied to S, W or welded plate W columns.
Auto base plate and cap plate * * or 'Auto Standard '
Auto base/cap plates are generally designed to frame to a beam or support a joist. They can be applied to wide flange, S shape, welded plate W, welded plate box, tube or pipe columns. To get an auto base/cap plate on a column that does not frame to anything, you need to ' Force ' the connection, or it must be a ' User defined ' connection.
Transverse beam stiffeners designed with a base/cap plate * * or 'Auto Standard ' or 'User base/cap plate '
SDS/2 will design a full-depth stiffener plate on a beam (placed under or over a column with a base/cap plate) if the " Load " entered for the column is sufficiently large. Two stiffeners may be designed for a heavy " Load ." Design Criteria (in Job Options) has an option to " Always provide transverse beam stiffeners ." 27

A butt plate and fill plates are designed if the upper column's nominal depth is at least 2 inches less than the lower column.
Field welded column splices for tube columns *
* or 'Auto Standard '
Wide flange, S shape, welded plate wide flange, welded plate box or pipe columns can also be field welded. The butt plate in this example is shop welded to the lower column. If there were no butt plate, the two columns would be field welded, which means there would be no automatic 3D representation of the weld in SDS/2. 28

The Plate Definition Schedule in Job Options defines this connection. A ' User base/cap plate ' can be placed on a column that does not frame to anything. 29
Connections Applied on Horizontal Braces
A Survey of SDS/2 Connections
Connections Applied on Horizontal Braces ---- To have SDS/2 design a gusset plate on a horizontal brace, select ' Hbrc plate' (or 'User Defined ') as the " Input connection type" on the Horizontal Brace Edit window. Settings that control the design of the connection include the " Section size " of the brace, its framing situation, and the " Compression" or "Tension" load on the brace. ---- SDS/2 can design gussets on horizontal braces that frame to one beam or to a beam-tobeam corner or to a beam-to-beam corner with an interposed column. Connection design takes into account whether the brace frames to the web or flange of the beam. A shared gusset plate can be designed when two or three horizontal braces frame close together onto a beam. An intersection plate can be designed for two short braces intersecting with a longer brace. ---- SDS/2 can automatically generate connections on horizontal braces with L, W, S, WT, ST, pipe or tube sizes entered as the " Section size" on the Horizontal Brace Edit window. Angle horizontal braces may be double material in various configurations (two are shown on pages 31 & 32). ---- Horizontal braces may be input so they are perfectly horizontal or so that they slope up to 30 degrees from horizontal. The brace must be in the same plane as the beams it frames to. To get to a view that is in the same plane, Snap to Surface on the top flange of one of the beams, then enter a negative Relative Depth to get below the flange.
Wide flange horizontal brace
SDS/2 designs two gussets that shop weld to the beam web and field bolt to the horizontal brace's top and bottom flanges. The program can do this for most framing situations.

Connections Applied on Vertical Braces
Connections Applied on Vertical Braces ---- To have SDS/2 design a gusset plate on a vertical brace, select ' Vbrc plate' (or 'User defined ') as the " Input connection type " on the Vertical Brace Edit window. Settings that control the design of the connection include the " Section size" of the brace, its framing situation, and the " Compression " or "Tension" load on the brace. ---- SDS/2 can design gussets on vertical braces that frame to a beam or column or to a column and base or cap plate. A shared gusset plate can be designed when two or three vertical braces frame close together to a beam or to a column. An intersection plate can be designed when one end of each of two short braces share the same work point on the interior of a longer brace. ---- SDS/2 can generate connections on vertical braces with L, C, WT, ST, W, S, pipe or tube sizes entered as the " Section size" on the Vertical Brace Edit window. You can also enter welded plate wide flange material if its flanges are equal. Angle vertical braces may be double material in ' Star ' or 'Back-to-back ' configurations.
Double angle vertical brace to column
SDS/2 designs a gusset plate that welds to the column web (shown) or flange (not shown) and bolts between the two angles. It can also design connections on single angles or double angles in a ' Star ' configuration.
Single angle vertical brace to beam
For single angle braces where the leg to gusset is 5 inches (127 mm) or longer, you have the option to set a staggered bolt pattern. This is also true for " Double" angle braces that are ' Back-to-back .' 35

Connections Applied on Joists
A Survey of SDS/2 Connections
Connections Applied on Joists ---- You cannot display joists in a solid form. In stick form, a joist is represented by a dashed line. The reason for this is that joists vary from manufacturer to manufacturer, and it would be extremely difficult for SDS/2 to accurately model in 3D all of the manufacturing variations. ---- The specifications for joist section sizes are maintained in the local material file used by your job. These specifications are extremely important, since they set the placement of a joist's connections with respect to its work line. ---- SDS/2 can automatically design top chord seats for joists framing to columns, or generate holes, field bolts and a dummy plate on a beam flange for bolting the joist. The program can also design stabilizer plates or angle seats for extended bottom chords. ---- The Joist Setup window in Standard Fabricator Connections lets you set, among other items, the " Member edge distance for top chord seats " and the angle used for extended bottom chord seats.
Field bolts for a joist top chord to a beam flange
For SDS/2 to add holes and bolts and a dummy plate in the framing situation that is shown, the " End elevation" of the joist must be the beam's top flange plus the " Bearing depth" of the joist, which is set in the local material file. The bolt " Gage" is also set in the local material file.
Plate seat for the top chord of a joist
This type of seat is a built-up tee made of welded plates. The seat is the " Bearing depth" distance (entered in the local material file) below the work line of the joist. 40

Plate seat for the top chord of a sloping joist
The supporting surface of a plate seat for a sloping joist does not slope. This is quite different from a plate seat for a sloping beam, which will be designed with a supporting surface that is equal to the slope of the beam.
Angle seat for the top chord of a joist
Angles must be listed in the " Angles" list in Standard Fabricator Connections . If they are not, SDS/2 will instead design a seat made of plate material.

Revise & Review Fields for User/User Defined Connections This is a survey of some of the many User/User Defined Connections whose settings you can adjust. More connections, along with more detailed information about individual revise & review fields, can be found in the SDS/2 context-sensitive help manual. To make entries to revise and review fields: User defined Connections: If the box ' AUTO' is checked for a particular revise & review field, SDS/2 will define that setting for you by applying Job Options or Fabricator Options during the design of the connection. To enter a setting of your own, click the check box next to ' AUTO' so that it is not checked, then make the appropriate type of entry. User Connections: If the "Connection " on a member edit window ( Beam Edit , Column Edit , etc.) is set to ' System ,' then the revise & review fields are disabled (grayed out). To change a setting, reset the " Connection " to 'User ,' then make the appropriate type of entry. Note that when you click in a revise & review field, other revise & review fields that may potentially be updated when you make a change to your current field will be highlighted in pink. How illustrations in this guide were created:
Typically these illustrations were created by generating member details in SDS/2, then modifying those details in SDS/2 to show the framing member. The details were then exported to another CAD program using SDS/2's Drawing Conversion program. Annotations were added, and then the drawings were saved in the .eps (Encapsulated Postscript) format. GIF versions of all of these drawings, plus some more drawings, can be found in the SDS/2 context-sensitive help manual.

SDS/2 shop welds the gusset to the column and base plate in this situation. The example shows an angle vertical brace with a staggered hole pattern, but a similar gusset plate would be designed for a W tee brace or double angle or channel or pipe or tube brace in the same situation. Note that " Bolt rows" on a vertical brace gusset plate run perpendicular to the work line of the vertical brace and the " Plate length" runs parallel with the work line of the column. The "Plate width" is measured perpendicular to the work line of the column, and " Bolt columns" run parallel with the work line of the brace. Revise & review fields not shown on this diagram:

Comments:
Although only two braces are shown in this example, SDS/2 can design a gusset plate for three wide flange vertical braces if the middle brace is perpendicular to the beam. The revise & review buttons you get for two braces sharing a gusset are: " This Half " and "Other Half ." For three braces you get: "This Brace " and "Other [#]" ("#" is the member number of the brace). " This Half " (or "This Brace ") refers to the vertical brace you are editing. The " Other Half " (or "Other [#]") is another brace that shares the same gusset. If you change revise & review settings or other settings for one wide flange vertical brace, it may be necessary to change equivalent settings for the other vertical braces.

Parametric point maps
Parametric Point Maps When you Record a Material Add operation in Parametric Modeling, an expression similar to the following will automatically be entered to the " Point 1" and "Point 2" fields on the parametric material window: mem.LeftEnd.Location + mem.TranslateToGlobal(X,Y,Z)
In the above expression, "mem.LeftEnd.Location" is the left end work point of the member. The operation "+ mem.TranslateToGlobal(X,Y,Z)" defines individual X, Y and Z member coordinate distances and adds those distances to the member's left end work point in order to define a new point in global coordinates. During Record , SDS/2's Parametric Modeling routines automatically calculate particular distances (in real numbers) for X, Y and Z in this expression. But to create an effective script that adapts to many different situations, you may find it useful to define X, Y and Z using formulas instead of numbers. The parametric point maps on the following pages show you various formulas that you can substitute for X, Y or Z in the above expression in order to define points on the left or right end of a member's main material. Following is an example of a very simple Python script that uses formulas from the parametric point map on the next page to define a point (var) at which a pair of construction lines intersects. When a user Runs or Tests this parametric, the program will automatically place a pair of cyan-colored construction lines that intersect at the left end top flange near side gage line of the particular member that the user clicks on. # Adds construction lines on left end, near side, top flange gage line of member that is selected ... # insert startup code mem = MemberLocate("Select a member") var = mem.LeftEnd.Location + mem.TranslateToGlobal(mem.left.minus_dim, 0, mem.gage*.5) # construction line begin cl1 = ConsLine() cl1.Point1 = var cl1.Rotation = 90 cl1.PenNumber = "Cyan" cl1.Add() # construction line end # construction line begin cl2 = ConsLine() cl2.Point1 = var cl2.Rotation = 0 cl2.PenNumber = "Cyan" cl2.Add() # construction line end
Note: In this example, left is a valid alias for LeftEnd , minus_dim is a valid alias for MinusDimension, gage is a valid alias for FlangeGage . The shorter aliases were used here and on the following pages to save space. 101
