" Brace Connection To Gusset " connection design locks

A wide flange vertical brace field bolts to a gusset plate per choices made to " Brace Connection To Gusset " locks. The wide flange brace's flanges are cut flush to the side of the web (NS or FS) that field bolts to the gusset (" Side of gusset " = ' Near side ' or ' Far side '). The gusset shop attaches to a column per choices made to either " Weld Conn2 " or " NS/FS Clip Conn2 " locks.


(W vertical brace, field bolted directly to gusset, to a column)
(vertical brace " Section size " = wide flange)
(" Input connection type " = ' Vbrc Plate ' or ' User defined ')
(" Web orientation " = ' Vertical ')
(" Side of gusset " = ' Near side ' or ' Far side ')
" Brace Connection To Gusset "
(hole pattern for field bolts)


The gusset plate can shop weld to the column (" Weld Conn2 ") or shop bolt with a clip angle (" NS/FS Clip Conn2 "). A wide flange column is shown, but the column can also be other material types . Click here for an example from the Connection Guide.

User Defined Connections: Settings that are locked ( ) in the user defined connection file will automatically be locked on the member edit window. You can, if you so choose, manually lock additional settings on the member edit window, and your changes will be retained, through multiple processes, so long as you do not change to a different connection then switch back to the original user defined connection.

Vertical Brace Edit: To change a setting, first set it to locked ( ). Related settings that are unlocked ( ) may be updated, and the " Left/Right end limit state " calculations will be updated. Settings that are locked ( ) will not be changed by connection design , even if doing so might prevent a connection failure.

VIDEO A wide flange vertical brace produces the failure message, " WF brace flg is too narrow for connection ." This is fixed by switching the " Side of gusset " from ' Center ' to ' Near side ' or ' Far side ', thus field bolting the web of the wide flange directly to the gusset.

Connection design locks :

Locks not dimensioned or called out on the drawing are marked ( not depicted ).

  Brace Connection To Gusset
( wide flange vertical brace, web field bolted to gusset, to a column )

Bolt diameter ( not depicted ): You can either type in any diameter (inches or mm), or you can select a bolt diameter from the combo box ( ). The diameters that are listed in the combo box come from Home > Project Settings > Job > Bolt Settings > the " Available bolt diameters " list. The bolt diameter entered here, together with the " Hole type " entered below, set the diameter of holes through the gusset plate and the brace.

Hole type ( not depicted ): Standard round or Short slot or Oversized or Long slot or User slot #1 or User slot #2 . The hole type selected here, together with the " Bolt diameter " entered below, determine the diameter of holes for field bolting the wide flange vertical brace to the gusset plate.

Rows: The total number of holes in any column of holes on the vertical brace gusset plate. For the wide flange vertical brace shown in the example above, the number of " Rows " is ' 2 '.

Distance to 1st hole along brace ( to 1st hole ): The distance (parallel with the work line of the vertical brace) from the work point for this end of the vertical brace to the center of the nearest hole in the brace-to-gusset connection (see example ).

Hole spacing along brace ( row spacing ): The distance (center to center) between of any two adjacent holes in the same column of holes in the gusset plate (see example ).

End connection failure message: Invalid bolt spacing

Edge distance along brace ( edge dist ): The distance from the forward edge of the brace to the nearest hole. This distance is measured along the work line of the wide flange vertical brace. The forward edge is the brace's edge that is nearest to its work point.

Other edge distance along brace ( other edge dist ): The distance from the connection edge of the gusset plate to the nearest hole for field bolting the brace to the gusset. This distance is measured along the work line of the wide flange vertical brace.

Columns: The number of columns of holes in the gusset plate. These holes are used for field bolting the wide flange vertical brace to the gusset. In the example above, the number of " Columns " is ' 2 '.

Distance to 1st hole perpendicular to brace ( not depicted ): The distance from the work line of the vertical brace perpendicular to the nearest column of holes in the brace-to-gusset connection. In the example above, this distance would be ' 0 ' (zero) since the nearest column of holes is centered over the work line of the brace.

Hole spacing perpendicular to brace ( column spacing ): The distance (center to center) between any two columns of holes (see example ). Column spacing runs perpendicular to the work line of the vertical brace.
