Section size: The main material (e. g. ' L4x4x1/2 ') of the vertical brace(s). Only materials listed in the local shape file can be specified here.
Round bar material may have been entered as the vertical brace " Section size " in order for the program to have designed rod bracing .
Vertical brace member worklines (stick form lines) are drawn through the neutral axes of wide flange , S shape , welded plate wide flange , HSS round , round bar or HSS rectangular braces.
For a W tee or S tee vertical brace, the workline is drawn through the top flange center line if the stem is ' Horizontal ' or along the connection bolt line if the stem is ' Vertical '.
For a single angle vertical brace, the workline is drawn along the leg to gusset per " General settings " > " Locate on neutral axis ." For a channel vertical brace, the workline is at the half-depth line of the heel of the channel (the channel web is vertical).

. This " General settings " option applies when an angle section has been entered as the vertical brace's " Section size ."
|
If this box is checked ( ), connection design creates a single column of bolts to connect the angle to the gusset. This may result in a gusset plate that is larger or thicker.
|
|
If the box is not checked ( ), connection design creates two columns of bolts to connect the angle to the gusset when the length of the angle leg to the gusset is greater than 5 inches (127 mm).
|
Stagger bolts: or . This " General settings " option applies when an angle section has been entered as the vertical brace's " Section size " and the leg to gusset is 5 inches (127 mm) or longer.
|
If this box is checked ( ), connection design staggers the bolts that connect the angle to the gusset. The program may increase the row spacing (for example, from 3 inches to 3 1/2 inches) to keep bolts on different gage lines farther apart than 2 2/3 times the bolt diameter.
|
|
If the box is not checked ( ), connection design creates two columns of non-staggered bolts to connect the angle brace to the gusset. This may result in an extra bolt being used and cause the gusset plate to be larger than it would be otherwise.

If this box is checked ( ) and this brace has been auto detailed in a full-featured SDS2 program , the brace's bill of material lists the welded plate wide flange or welded plate box section as a single section size. A single submaterial detail is drawn to depict the welded plate section.
If the box is not checked ( ) and this column has been auto detailed , the braces's bill of material will list the welded plate wide flange section as three plates (four plates for a welded plate box). Separate submaterial details are drawn for the plates.
Break Apart :
Stem orientation: Horizontal or Vertical . This " General settings " option applies when the vertical brace's " Section size " is a W tee or S tee section.
|
' Horizontal ' bolts the flange of the tee directly to the gusset plate. The top flange center line of the tee aligns with the work line of the brace.
|
|
' Vertical ' aligns the forward edge of the tee with the gusset and connects the gusset and brace with a bolted connection plate. The bottom bolt line aligns with the workline of the brace if the stem is ' Up ' (as shown). The top bolt line aligns with the workline if the stem is ' Down '.
|
>Connection type: Web plates or Coped flange . This " General settings " option applies to a W tee or S tee vertical brace whose " Stem orientation " is ' Vertical '.
' Web plates ' indicates that the connection on this end of the brace uses NS and FS web plates to field bolt the brace to the gusset. The web plates shop bolt to the brace. Web or gusset fill plates are provided as needed.
' Coped flange ' indicates that the stem-vertical tee's NS or FS flange has been cut with a " Cut flange flush " top/bottom flange operation and that the stem of the tee has been field bolted to the gusset plate. Also see " Side of gusset " (' Near side ' or ' Far side ').
Long leg: Outstanding or To gusset . This " General settings " option applies when an angle with unequal legs has been entered as the vertical brace's " Section size ."
|
' Outstanding ' bolts the short leg of the angle brace to the gusset plate, with the long leg outstanding.
|
|
' To gusset ' bolts the long leg of the angle vertical brace to the gusset plate.
|
Angle leg turned up: or . This " General settings " option applies when the vertical brace's " Section size " is an angle. Connection design in a full-featured SDS2 program can create a ' Vbrc plate ' for a leg-up single- or double-angle brace in the same framing conditions that it can for a leg-down angle brace. It can also design a ' Welded ' connection on a leg-up double-angle vertical brace (' Back to back ') to the stem of a W tee (or S tee) chord member.
|
If this box is checked ( ), connection design points the leg of the angle up. The angle is oriented so that the leg that bolts to the gusset plate is above the outstanding leg.
|
|
If the box is not checked ( ), connection design points the leg of the angle down. The angle is oriented so that its outstanding leg is above the leg that bolts to the gusset plate.
|
Double material: or . This " General settings " option applies when the vertical brace's " Section size " is an angle or channel .
If this box is checked ( ), the vertical brace main material is double material (back-to-back or in a star configuration).
If the box is not checked ( ), the vertical brace is a single angle or channel.
Configuration: Back to back or Star or Near side or Far side . This " General settings " option applies when the vertical brace's " Section size " is an angle and the box for " Double material " is checked.

If ' Back to back ' is selected, the two angles are laid out back-to-back with a spacer (stitch plate) in between. This example shows a bolted ring or bolted plate spacer.
If ' Star ' is selected, the two angles are laid out in a star configuration using vertical spacers (stitch plates). A bolted spacer is used in this example.
' Near side ' places the angles back-to-back on the near side of the gusset plate. No stitch plate is required. The gusset plate, not a stitch plate, is shown in the above example.
' Far side ' places the angles back-to-back on the far side of the gusset plate. No stitch plate is required. The gusset plate, not a stitch plate, is shown in the above example.
Stitch plates are required for ' Back to back ' and ' Star ' configurations. The " Type of spacer " that will be applied is specified in Member Detailing and Fabricator Options . The " Stitch plate gap " and " Maximum stitch plate spacing " and " Number of stitch plates " is set on this window.
Side of gusset: Center or Near side or Far side . This " General settings " option applies to W tee (or S tee ) or angle or channel vertical braces. A stem-horizontal W tee or S tee brace will attach to the gusset much like an angle brace. For " Side of gusset " to apply to a stem-vertical W tee or S tee, its " Connection type " must be set to ' Coped flange ." " Side of gusset " may apply to wide flange vertical brace whose " Web orientation " is set to ' Vertical '.
' Center ' may be applied when the " Section size " is a wide flange. If the brace was previously set to ' Near side ' or ' Far side ', this removes the previously applied connections (each end). The " Connection arrangement " that is set under left- and right-end " Connection specifications ' will be the newly applied end connections.
' Near side ' indicates that the outstanding leg of the angle (toes of the channel, stem of a stem-horizontal W tee) are pointed toward you when you are facing the near side of the material. The near side of a vertical brace is the side facing you when the brace's left end is to your left. For a stem-vertical W tee, this places the stem forward to the near side of the gusset plate.
' Far side ' indicates that the outstanding leg of the angle (toes of the channel, stem of a stem-horizontal W tee) point away from you when you are facing the near side of the material.
Stem direction: Up or Down . This " General settings " option applies to a W tee or S tee vertical brace whose " Stem orientation " is ' Vertical '. The vertical brace end's " Connection type " can be ' Web plates ' or ' Coped flange '.

In a full-featured SDS2 program . . .
' Automatic ' instructs connection design to apply the choice made to Home > Project Settings > Job > Design Settings > " Seismic vertical brace gusset design ."
' Yes ' specifies that connection design create a seismic connection on both ends of the brace. If ' Auto ' is selected for the vertical brace's " Tension load " and/or " Compression load ," connection design creates a connection with seismic loading on that end of the vertical brace. If ' 
SCBF ' is selected for the vertical brace, the " Multiplication factor... " at Home > Project Settings > Job > Plate Design Settings is used to set the distance parallel with the brace member line from the end of the brace (or paddle plate or built-up tee) to the nearest corner of the gusset. For HSS /TS seismic braces, connection design creates reinforcement plates with locks that are contained in the " Brace Reinforcement " leaf ( 
) . For 2-point gusset plates, the option " AISC seismic 1st ed. 2pt gussets " sets whether the design is based on the 1st or 2nd edition of the AISC seismic design manual. For 2-point bracing to a column flange, a " Web Doublers " leaf becomes available for the adding of supporting member web doublers. The " Web Doublers " leaf is populated automatically when the supporting member is a thin-web beam or thin-web column. For a seismic vertical brace or 2-point braces to a column web, the " Stiffener Plate " leaf may, if the column web is too thin, be populated with values that generate the design of column web stiffeners.
' No ' configures connection design to create a non-seismic connection. The gusset will likely be smaller, and the end of the brace will likely be closer to the supporting member. For 2-point bracing, web doublers will not be designed as needed on the supporting member. Brace reinforcement will not automatically be added for HSS/TS vertical braces. Users of a full-featured SDS2 program can still get web doublers for non-seismic 2-point bracing by selecting ' As needed ' for " Check supporting for web shear " in " Connection specifications ." For non-seismic HSS/TS braces, users of that program can still get connection design to create reinforcement plates by entering a " Plate thickness " in the " Brace Reinforcement " leaf.

See the topic " Determining left end & near side " if you are unsure which end of this brace is the left end or the right end.
End elevation: The elevation (in the primary dimension " Units " or in other units ) of the work point for this end of the vertical brace.
These work points align with the neutral axis of a wide flange , HSS round or HSS rectangular vertical brace.
For a W tee vertical brace, the work points align with the top flange center line (the top flange is vertical).
For a single angle vertical brace, the work points align with the gage line of the angle (the vertical dimension from the heel of the angle to the first hole).
For a channel vertical brace, the work points align with the half-depth line of the heel of the channel (the channel web is vertical).
Tip: To determine the end elevation on a vertical brace while working in the 3D model, invoke a command like Construction Line Add , select EXPT as the Locate option, then move the point location target to the work point at the end of a vertical brace and reference the Z coordinate reported in the X-Y-Z display .

Input connection type: User defined or Plain end or Vbrc plate or Welded . To review the results of the way that connection design in a full-featured SDS2 program has actually created a connection, review the connection design locks .
' User defined ' means that connection design will use the user defined connection file name that is entered to " User defined connection ."
' Plain end ' means connection design will not create a connection on this end of the brace.
' VBrc plate ' instructs connection design to create a gusset plate on this end of the brace according to the framing situation. Different connection plates will be designed for brace-to-beam, brace-to-column and brace-to-beam & column framing situations. Also, the materials used for the brace and framed-to members affect the gusset design. For an angle , W tee or channel vertical brace framing to a beam and column, the program will design the gusset-to-column interface with the same connection type that is designed for the beam as long as that connection type is a clip angle or shear plate or end plate . In other words, if the beam connects to the column with a shear plate, so will the vertical brace.
' Welded ' can be used for creating trusses and fully-welded connections. Connection design can create a welded connection in the following situations:
For an HSS ( pipe or tube ) vertical brace to an HSS chord member (beam): The program Exact Fits this pipe brace to the other HSS brace or chord member, then welds the sections. For 3-point HSS braces (tube or pipe), the center brace fits to the chord and the other braces fit to the center brace. For 2-point braces , the brace with the lower member number [num] fits to the chord. The " Field clearance " sets the fit clearance to the cord or other brace. Click here for examples.
For an HSS ( pipe or tube ) vertical brace to a wide flange beam, column, or vertical brace flange: Connection design fits the end of the pipe or tube
flush to the supporting member's flange and welds it with an all-around fillet weld. Transverse stiffeners might also be created on the supporting member to stiffen the web. For setup of this connection, see " Plate Design Settings ".
Double-angle vertical brace (' Back to back ') to the stem of a W tee (or S tee) chord member (beam): Connection design welds the angles to the stem of the tee. For setup of this type of brace, see " Brace to supporting member " (field clearance), " Brace to brace " (field clearance), " Weld all around angle branch ," " Connection weld size " and " Type of spacer for welded connections ." Click here for examples.
Design of the " Input connection type " shown here takes place in a full-featured SDS2 program .
" Connection specifications " and " Connection design locks " provide settings for finer control of a connection's design.
The " Design Calc " or " Expanded Calc " button on this window gives you the connection's design calculations.
User defined connection: The file name of the user defined connection to be applied on this end of the vertical brace.
This " Connection type " option applies when ' User defined ' is the " Input connection type ."
System designed connection: The type of connection that connection design creates on this end of the brace (e.g. ' Vbrc plate ' or ' Plain end ').
NM bolt type: Auto or A325N or A325SC or A325X , etc. NM stands for "non-moment."
If " Auto " is checked ( ), connection design creates the connection on this end of the brace using the Home > Project Settings > Job > Bolts, Washers, and Holes > Bolt Settings > " Default non-moment bolt type ."

If " Auto " is checked ( ), connection design calculates the tension load on this end of the member using the value entered to " Brace design tension. . . % of allowable load " in Design Settings . The calculated numerical value -- calculated in this example -- is the actual value that is used to design the connection on this end of the vertical brace. Design method considerations: For ' ASD ' or ' LRFD ', the " Auto " tension load is calculated per Section D2. For ' CISC 8 ' or ' CISC 9 ', it is calculated per Clause 13.2. For ' AS 4100 ', it is calculated in accordance with Clause 7.2. A special case : " Seismic brace " design increases the magnitude of the calculated auto tension load.
If " Auto " is not checked ( ), a user of a full-featured SDS2 program has set the load. The user-entered value is used to design the connection.

The calculated numerical value -- calculated in this example -- is the actual value that is used to design the connection on this end of the vertical brace. Design method considerations: For ' ASD ' or ' LRFD ', the " Auto " compression load is calculated in accordance with Section E3. For ' CISC 8 ' or ' CISC 9 ', it is calculated in accordance with Clause 13.3. For ' AS 4100 ', it is calculated in accordance with Clause 6.3. A special case : " Seismic brace " design increases the magnitude of the calculated auto compression load.
If " Auto " is not checked ( ), a user of a full-featured SDS2 program has set the load. The user-entered value is used to design the connection.
Status Display: Member status > Left end compression load and Right end compression load
Status Display: Connection auto loads > Auto vertical brace compression

- A left- and right-end " Summary " can be shown on this window only if you are editing one vertical brace. There is no summary if you are editing multiple vertical braces.
- The " Summary " leaf gives you a summary of connection information related to the left or right end of the vertical brace.
- The summary shows (in parentheses) the " System designed connection ."
- If other vertical braces have been assigned the same piecemark as this vertical brace, the summary lists those other vertical braces by member number (149 & 153 in this example).
- If this vertical brace is part of a group member, the summary lists the group member piecemark .
- The " Maximum tension load " and " Maximum compression load " show the capacity of the connection.
- " Connection design locks " and " End preparations " that were locked ( ) because the " Input connection type " is ' User defined ' are reported as " Locked Via User Defined ." All other locks that are locked ( ) are reported as " Locked Via Member Edit ."

Design Calculations Report: Connection Design Lock Summary
- This documentation categorizes connection design locks by framing situation.
- Locked ( ) connection design locks are entries made by users of a full-featured SDS2 program .
- Unlocked (
) connection design locks are computer-generated values entered by connection design . In many cases, connection design populates the unlocked fields based on user-entered setup choices.
- The limit state information tells you the capacity of the designed connection.
- These same connection design locks may also be found on the Connection Component Edit window for this connection.
- When checked, " Show images " lets you see drawings that depict dimensions associated with connection design locks.
- Connection design locks are grouped together under leaves with the following names:
Various Framing Situations
|
Vertical Brace to a Column
|
Vertical Brace Intersection (X bracing)
|
Vertical Brace to a Beam & Column
|
Vertical Brace 2- or 3-Point Shared Gusset to a Beam
|
Vertical Brace 2- or 3-Point Shared Gusset to a Column
|
Vertical Brace to a Column & Base/Cap Plate

These limit states are for a stem-vertical tee brace with a web plate connection to the gusset. A clip angle connects the gusset to the supporting beam. The values shown represent the strength capacity of the connection or of the supported member (this vertical brace). In this example, the connection passes.
(T) = tension
(C) = compression
|
- A limit state is a potential connection failure mode.
- The capacity of a connection is calculated for various limit states during connection design . Each " Value " reported in the example above represents the strength of the connection or of the vertical brace itself or of its supporting member with respect to a particular limit state.
- Since connection design takes place in a full-featured SDS2 program , but not in Site Planning, the limit states that are reported on this review-only window are static and cannot be changed.
- If connection design in a full-featured program has determined that the capacity of a connection is insufficient to stand up to the " Loads " on the vertical brace, or if there is a geometry problem related, for example, to the work points of the brace, the program will have failed the connection and generated a connection failure message such as:
| Gusset extends past the end of the member
|

- The following custom components are distributed with SDS2 programs and may be applied to vertical braces. You therefore can potentially find settings for them on the Vertical Brace Review window:
- Custom component settings will be shown on this window after a custom component has been added to this vertical brace in a full-featured SDS2 program .
- Settings for custom components from outside distributors can also be reviewed on this window. However, since such custom components are not distributed with SDS2 programs, they are not documented in this help manual.
- Tip: An alternative to reviewing a custom component on this window is to double-click material generated by that custom component in the model. The program will open a custom component review window that includes all the settings for that custom component, but does not include the other settings that can be found on the Vertical Brace Review window.

"Properties" opens the Edit Properties window, on which you can make entries to custom properties . If, at the time it was created, your current Job was set to use a legacy flavor, the window that opens is named Custom Properties , not Edit Properties .
The Edit Properties window can also be used to read " Log " entries or review or type " Notes ."
Tip: Model > Member > Properties is an alternative to this button. It opens the Edit Properties window directly, without your first having to open a member review window.
" Status " opens the Member Status Review window for the vertical brace(s) that you are reviewing. You can use that window to update status information about the vertical brace(s).
" OK " (or the Enter key) closes the Vertical Brace Review window (this window) and saves to the member file(s) any changes made on the Member Status Review window.
Change all: If you double-clicked a vertical brace and made a change to its status and the 3D model contains other vertical braces with the same piecemark as this brace, a yes-no dialog opens after you press " OK ." On that yes-no dialog is the question, " Do you want to change all .... " Press the " Yes " button to update the status of all the vertical braces with this piecemark; press the " No " button to change only this one brace.
Tip: The yes-no "change all" dialog tells you the count of the members with this " Piecemark ." Another way to find out the count of members under the piecemark is to look under the " Summary " on this window.
" Cancel " (or the Esc key) closes this window without saving any status changes made on the Member Status Review window.
" Reset " undoes all status changes you made to this member on the Member Status Review window.
"Design Calc" outputs a report that includes this brace's design calculations, general settings and left/right end settings. If you are reviewing multiple braces with the same piecemark (or with different piecemarks), you get a report for each brace. Each report is output to the destination specified at User and Site Options > Output > " Reports ."

Tip: To get a report listing similar specifications for multiple members, output a Check Report and a Design Calculations Report .
"Expanded Calc" outputs the Expanded Connection Design Calculations . Output is to your web browser.
Expanded Connection Design Calculations is a report that provides all of the information in the Connection Design Calculations combined with related information from the Connection Calculation Cover Sheet . In addition, the report shows you the calculations written out, in detail, in the report itself, instead of simply reporting the results. Certain browser requirements must be met in order for you to access this report.
If you are reviewing multiple vertical braces with the same piecemark (or different piecemarks), you get a report for each brace.
Connection design failures can be found with the aid of a search or by a quick scan of the document. Calculations that result in a connection failure are identified as " (NO GOOD) " in their concluding line. You might also search for the string "CONNECTION DESIGN FAILURE".
