Valid Material Types for Horizontal Brace Connections
(A full-featured SDS2 program can generate horizontal brace connections when the horizontal brace's " Section size " is one of these material types.)
W , L , WT , HSS round (pipe), HSS rectangular (tube), S , ST A full-featured SDS2 program can generate system connections on a horizontal brace with a " Section size " of W, L, WT, HSS round (pipe), HSS rectangular (tube), S or ST material. Pipe and tube braces are designed with built-up tee fittings that bolt to the gusset.
work lines
(stick form member lines)
For a single angle horizontal brace, the work line is drawn along leg of the angle that attaches to the gusset per " General settings " > " Locate on neutral axis ."
For a W tee or S tee or W or S horizontal brace, the work line is drawn across the top flange center line (top flange is parallel with the top flange of the beam).
For an HSS horizontal brace ( round or rectangular ), the work line is drawn through the neutral axis.
members a horizontal brace can connect to: A full-featured SDS2 program can automatically generate connections for horizontal braces with valid section sizes framing to wide flange , welded plate W , S shape , channel , or HSS rectangular beams.

Long leg: Outstanding or To gusset . This " General settings " option applies when an angle with unequal legs has been entered as the horizontal brace's " Section size ."

' Outstanding ' bolts the short leg of the angle to the gusset. For a non-sloping horizontal brace, this makes the long leg vertical.

' To gusset ' bolts the long leg of the angle to the gusset plate. For a non-sloping horizontal brace, this makes the long leg horizontal.

Double material: or . This " General settings " option applies when an angle has been entered as the horizontal brace's " Section size ."

If this box is checked ( ), the horizontal brace is a double angle brace. The angles are back-to-back if either ' Near ' or ' Far ' is selected for " Side of gusset ." One angle is on the far side of the gusset and the other is on the near side if both ' Both sides ' are selected for " Side of gusset ."

If the box is not checked ( ), the horizontal brace is a single angle.

One gage line: or . This " General settings " options applies when an angle has been entered as the horizontal brace's " Section size ."

If this box is checked ( ), connection design in a full-featured SDS2 program applies a single column of bolts at the angle-to-gusset interface. This may result in a gusset plate that is larger or thicker.

If the box is not checked ( ), the program designs the angle-to-gusset interface with two columns of bolts 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 has been entered as the horizontal brace's " Section size " and the leg to gusset is 5 inches (127 mm) or longer.

If this box is checked ( ), connection design in a full-featured SDS2 program applies a staggered bolt pattern on braces with two columns of bolts at the angle-to-gusset interface.

If the box is not checked ( ), the two columns of bolts that fasten the angle to the gusset are not staggered.

Side of gusset: Near side or Far side or Both sides . This " General settings " option is for selecting the face of the gusset plate for attachment of an angle or tee or double angle horizontal brace.

' Near side ' fastens the horizontal brace to the near side face (the top face) of the gusset plate. The near side face is the face that you look down on in a plan view.

' Far side ' fastens the horizontal brace to the far side of the gusset plate (the bottom face of the gusset plate).

' Both sides ' only applies when the box for " Double material " is checked. The program uses the " Type of spacer " that is specified in Member Detailing and Fabricator Options .

Long side: Vertical or Horizontal . This " General settings " option applies when a tube has been entered as the horizontal brace's " Section size ."

' Vertical '
' Horizontal '

' Vertical ' indicates that the long side of the tube brace is vertical.

' Horizontal ' indicates that the long side of the tube brace is horizontal.

Status Display: Member status > HSS long side orientation

Allow material workline offset: Automatic or Yes or No The top surface of, for example, an angle or W tee horizontal brace is normally in the same plane as the brace's work line . This " General settings " option gives connection design (in a full-featured SDS2 program) permission to offset the main material of a brace so long as that brace has at least one end that frames to a beam's bottom flange. The option does not affect most horizontal braces.

A material workline offset is allowed when a horizontal brace frames to the bottom flange of a beam. To get a connection in such a situation, the beam workline must be in the same plane as the beam's bottom flange.

' Automatic ' applies the choice made to " Allow material workline offset " in Member Detailing & Fabrication Options ( Fabricator Setup ).

' Yes ' allows connection design (in a full-featured SDS2 program ) to offset the main material of the horizontal brace by the thickness of the gusset plate so that the brace can connect to the bottom flange of the beam. This affects both connections on the brace, even if, for example, one end of the brace goes to the bottom flange of a beam and the other end goes to the web of a different beam..

' No ' indicates that the main material of the brace is not offset. If at least one end of the brace frames to the bottom flange of a beam, the connection on that end will fail with the message " Invalid brace work point location ."

Minimum gusset thickness: Auto or a user-entered thickness (in the primary dimension " Units " or in other units ).

If " Auto " is checked ( ), then a full-featured SDS2 program designs a gusset plate that is as thick or thicker than the Home > Project Settings > Fabricator > Standard Fabricator Connections > Gusset Plate Settings > " Minimum gusset plate thickness ."

If " Auto " is not checked ( ), a gusset plate is designed to be as thick or thicker than the minimum thickness shown here.

Locate on neutral axis: Automatic or Yes or No . This " General settings " option applies when the horizontal brace's " Section size " is an angle . No matter what choice is made here, the work line of the horizontal brace runs along the surface of the angle leg that attaches to the gusset.

workline ( x )
on neutral axis
workline ( x )
on gage line

' Automatic ' indicates the horizontal brace angle material is aligned with its work line per the choice made to Home > Project Settings > Fabricator > Member Detailing & Fabrication Options > the " Horizontal Braces " section > " Locate angle braces on neutral axis ."

' Yes ' indicates that the angle material's X-X axis or Y-Y axis (shown in the AISC Structural Shapes tables) intersects with the workline of the brace.

' No ' indicates that the gage line of the angle material aligns with the workline of the brace. An angle's gage line is the " Long leg gage " or " Short leg gage " entered in the local shape file.

Stitch plate gap: Auto or a user-entered distance . This " General settings " option sets the gap between " Double material " angle braces and also sets the thickness of the stitch plate ( spacer ).

stitch plate gap = 0
stitch plate gap > 0

If the box for " Auto " is checked ( ), a full-featured SDS2 program applies the distance entered to " Back to back angle stitch plate gap " in Detail Members and Fabrication Options (setup) as the gap between the "backs" of a back-to-back double-angle horizontal brace. For double-angle horizontal braces on ' Both sides ' of the gusset, the program designs the gap to be the thickness of the gusset.

If the box for " Auto " is not checked ( ), then the distance entered here (in the primary dimension " Units " or in other units ) sets the gap that separates the two angles that make up the double-angle horizontal brace.

Max stitch plate spacing: Auto or a user-entered distance . This " General settings " option sets the distance (center-to-center) between stitch plates and the left/right end of the brace. Left/right end = end Left/right end ce material for a ' Plain end '. Left/right end = inside bolt if the end has a gusset. The actual spacing may be less than the spacing entered here.

s = spacing

Number of stitch plates: Auto or a user-entered number . This " General settings " option sets the number ( 1 or 2 or 3 ...) of stitch plates.

WP to WP length, plan: The work point-to-work point distance spanned by the horizontal brace workline in a plan view, ignoring elevation. This " General settings " distance is calculated from the X and Y (but not Z) global coordinates of the brace work points.

For a horizontal brace that is perfectly horizontal, the distance reported is the same as the " WP to WP length: actual ." For a horizontal brace that is sloping, this is the horizontal distance (measured at a single elevation and along the X axis of the brace) from the worklines of the beams the horizontal brace frames to.

Work point-to-work point length is not selectable and cannot be entered directly by the user. This distance is automatically calculated from the work points of the horizontal brace.

WP to WP length, actual: The actual length of the horizontal brace workline .

This " General settings " distance is calculated from the X and Y and Z global coordinates of the horizontal brace work points.

" Member " settings are separated under [ Left End Settings ] and [ Right End Settings ] . See the topic " Determining left end & near side " if you are unsure which end of this brace is which.

End elevation: The elevation (in the primary dimension distance " Units ") of the work point at this end of the horizontal brace.

For a non-sloping horizontal brace, this is the elevation of: the top flange for a W tee ; neutral axis for an HSS ( round or rectangular ); leg to gusset for an L . Both ends of a non-sloping horizontal brace must be at the same elevation for connections to be designed.

In the examples below, the work point elevation determines whether the gusset plate fastens with clip angles to the webs of the beams ( left ) or bolts to the beam flanges ( right ).

flange level
 

Tip: To determine the end elevation on a horizontal 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 horizontal brace and reference the Z coordinate reported in the X-Y-Z display .

Standard detail: None or the file name of a job standard detail or global standard detail .

If ' none ' is shown here, then no standard detail will be applied on this end of the horizontal brace when this brace is automatically detailed .

If a ' standard detail name ' is shown here, the next time automatic detailing of this brace is done in a full-featured SDS2 program , the reference point of the standard detail will align with the input work point on this end of the brace, and the standard detail's bill of material will be combined with the braces's bill of material. The detail is placed on a layer that is named after the standard detail plus a "_L" or "_R" suffix.

   --- HBrc to a Beam's Web
   --- perpendicular to Beam
   ---  2- and 3-point, to top flange or web
   ---   HBrc Intersection (x bracing)
   ---  HBrc to a Beam-Beam Corner
   ---  HBrc to a Bm-Col-Bm Corner

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 (and revised) on the Connection Component Edit window for this connection.

When checked, " Show images " lets you see drawings that depict the dimensions associated with connection design locks.

These limit states are for an angle horizontal brace welded to the web of the supporting beam. The values shown represent the strength capacity of the connection or of the supported member (this horizontal brace) or the supporting member. 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 beam 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 SDS2 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 horizontal 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:

 Invalid brace work point location

The Design Calculations Report together with the Connection Calculation Cover Sheet (or the Expanded Connection Design Calculations as a stand-alone report) provide formulas and the results of calculations (or the actual calculations) that relate limit states to the design of the specific connection.

    Components

The following custom components are distributed with SDS2 programs and may be applied to horizontal braces. You therefore can potentially find settings for them on the Horizontal Brace Review window:

HSS Cap Plates

Custom component settings will be shown on this window after a custom component has been added to this horizontal 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 Horizontal 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 horizontal brace(s) that you are reviewing. You can use that window to update status information about the horizontal brace(s).

" OK " (or the Enter key) closes the Horizontal 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 brace and made a change to its status and the 3D model contains other horizontal 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 horizontal 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 different piecemarks), you get a report for each brace. Each report is output to the destination specified at User and Site Options > Output > " Reports ."

calcs

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 horizontal 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".
