Order of brace input affects how 2-point HSS welded connections are cut :

The lower member number fits to the chord.

The higher member number fits to the other brace.

------ Setup of ' Welded ' connections ------

• A welded connection cannot be auto standard. Users of a full-featured SDS2 program can define such a connection by choosing ' Welded ' as the " Input connection type " on the Vertical Brace window or by making a similar selection to " Connection type " at Home > Project Settings > Job > User Defined Connections .
• " Brace to supporting member " and " Brace to brace " in Field Clearances apply to welded back-to-back double-angle vertical braces to a W tee (or S tee) chord member.
• " Weld all around angle branch " in Welded Connection Settings also applies to welded back-to-back angle vertical braces to a W tee (or S tee) chord member.
• " Connection weld size " in Welded Connection Settings applies to both welded back-to-back angle vertical braces and to welded HSS vertical braces to an HSS beam.
• " Design transverse stiffeners for welded brace connection " in Home > Project Settings > Job > Design > Plate Design Settings applies to welded HSS and Pipe vertical braces connecting to a wide flange beam, column, or vertical brace flange.
• " Align transverse stiffeners for welded brace connection with " in Home > Project Settings > Job > Design > Plate Design Settings applies when Design transverse stiffeners for welded brace connection is set to As needed or Always.

------ " Connection specifications " for ' Welded ' connections ------

" Connection specifications " are read-only in SDS2 review stations. You can find this set of conn specs on the Vertical Brace Review window when ' Welded ' is the " Input connection type ." For a ' User defined ' input connection type, conn specs are not on the Vertical Brace Review window, but can be found at Home > Project Settings > Job > User Defined Connections .

Weld all around angle branch: Automatic or Yes or No . This applies to back-to-back double-angle vertical braces to a W tee (or S tee) chord member when ' Welded ' or possibly ' User defined ' is the " Input connection type ."

' Yes '

' No '

In a full-featured SDS2 program . . .

' Automatic ' applies the choice made to Home > Project Settings > Fabricator > Standard Fabricator Connections > Welded Connection Settings > " Weld all around angle branch ."

' Yes ' instructs connection design to weld all three edges of the angle that contact the stem of the W tee (or S tee) chord member.

' No ' welds only the top and bottom length edges of the angle, not its forward edge.

Use transverse support stiffener: Automatic or As needed or Always or Never . This " Connection specifications " option applies to HSS or Pipe vertical braces connecting to a wide flange beam, column, or vertical brace flange when ' Welded ' or possibly ' User defined ' is the " Input connection type ." The stiffener plates are located on the supporting wide flange member to stiffen the member's web.

In a full-featured SDS2 program . . .

' Automatic ' applies a setup choice ( Home > Project Settings > Job > Design > Plate Design Settings > " Design transverse stiffeners for welded brace connection ").

' As needed ' instructs connection design to create full-depth transverse stiffeners in this situation only if the vertical brace's " Load " is large enough that the supporting wide flange member's web capacity is exceeded and stiffeners are required.

' Always ' instructs connection design to always create full-depth transverse stiffeners, even if they are not required by connection design.

' Never ' instructs connection design to not create full-depth transverse stiffeners, even if they are required by connection design. A red banner will appear in " Information " that reads "Supporting member web/flange design checks removed by user". A similar message will appear in the vertical brace's design calculation.

Align stiffeners with: Automatic or Brace or Support . This " Connection specifications " option applies to HSS or Pipe vertical braces connecting to a wide flange beam, column, or vertical brace flange when connection design creates full-depth transverse stiffeners.

In a full-featured SDS2 program . . .

' Automatic ' applies a setup choice ( Home > Project Settings > Job > Design > Plate Design Settings > " Align transverse stiffeners for welded brace connection with ").

' Brace ' aligns the stiffeners with the geometry of the vertical brace.

' Support ' aligns the stiffeners perpendicular to the supporting wide flange member's flanges.
