" Brace Connection to Gusset " connection design locks

A wide flange vertical brace field bolts to a shared 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 shared gusset shop attaches to the column per choices made to " Weld Conn2 " or " NS/FS Clip Conn2 " locks.

2-point bracing is shown, but " Brace Connection To Gusset " locks also apply to 3-point bracing. The gusset can shop weld to the column (" Weld Conn 2 ") or, for 2-point bracing, can 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 bolted to a 2- or 3-point 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 web of the wide flange vertical 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, set the diameter of holes for field bolting the web of the wide flange vertical brace to the gusset plate.

Rows: The total number of holes in any column of holes in the vertical brace gusset plate (see example ). 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 gusset plate (see example ).

Hole spacing along brace ( rs ): Row spacing. This is the distance (center to center) between of any two adjacent holes in the same column of holes in the gusset plate (see example ). Bolt row spacing in a vertical brace gusset plate runs parallel with the work line of the vertical brace.

End connection failure message: Invalid bolt spacing

Edge distance along brace ( ed ): The distance from the forward edge of the vertical brace to the nearest hole in the brace. This distance is measured along the work line of the wide flange vertical brace. The forward edge of the brace is the edge nearest the work point.

Other edge distance along brace ( other ed ): 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 (see example ). These holes are for field bolting the vertical brace to the gusset. Bolt columns run parallel with the work line of the vertical brace. In the example above, the number of " Columns " is ' 2 '.

Hole spacing perpendicular to brace ( cs ): Column spacing. This is the distance (center to center) between any two columns of holes (see example ). Bolt column spacing runs perpendicular to the work line of the vertical brace. Holes within an individual column run parallel with the work line.
