The connection design locks for 2-point bracing (2 braces to a shared gusset) and 3-point bracing are essentially the same. However, you cannot connect a 3-point gusset plate to the supporting column with a clip angle ("
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 (

Gusset 2 Point
( web-horizontal wide flange vertical braces, flange gussets, to a column )
Shared gusset plate dimensions and location
Plate thickness ( not depicted ): The " Material thickness " of the near-side flange gusset. This also sets the thickness for the far-side flange gusset.
Width ( plate width ): The distance (perpendicular to the work line of the supporting column) from the framing edge of the gusset plate (which welds to the column in the example shown) to the opposite edge of the gusset plate (which is parallel with the framing edge of the gusset plate). If the column is perfectly vertical, the flange gusset " Width " can also be defined as the horizontal distance between the two vertical edges of the plate.
Length ( plate length ): The length of the framing edge of the gusset plate (which welds to the supporting column in the example shown). Flange gusset " Length " is measured parallel with the work line of the supporting column. Since the framing edge of the gusset plate is parallel with the column, the flange gusset " Length " is parallel with the work line of the column. If the column is vertical, the flange gusset " Length " can also be defined as the vertical distance between the two horizontal edges of the gusset plate.
Refy: The positive (+) or negative (-) distance (perpendicular to the supporting column's work line ) from the work point of the vertical brace to the framing edge of the gusset plate (which welds to the column's flange in the example shown). If the column is vertical, this distance is horizontal. Changing the " Refy " moves the gusset plate perpendicular to the work line of the column (horizontally if the column is vertical), but does not move the holes on the plate.
Left Brace [ member number ]
Refx ( refx left ): The positive (+) or negative (-) distance (parallel with the supporting column's work line ) from the work point of the left vertical brace to the corner of the framing edge of the gusset plate that is closest to the left end of the column (see example ). For a shared gusset plate to a perfectly vertical column, this distance is vertical. Changing the " Refx " moves the gusset plate parallel with the work line of the column, but does not move the holes on the plate. Hole positioning is governed by the "
Connection cut width ( cut width ): The distance (perpendicular to the work line of the supporting column) between the two corners of the left connection edge of the shared gusset plate. The left connection edge is the edge that the left vertical brace frames to (see example ). This distance is not the actual length of the edge, but the length of that edge as measured parallel with the depth of the column.
Connection cut length ( cut length ): The distance (parallel with the work line of the supporting column) between the two corners of the left connection edge of the shared gusset plate. The left connection edge is the edge that the left vertical brace frames to (see example ). This distance is not the actual length of the edge, but the length of that edge as measured parallel with the work line of the column.
Refx ( refx right ): The positive (+) or negative (-) distance (parallel with the supporting column's work line ) from the work point of the right vertical brace to the corner of the gusset plate's framing edge that is closest to the right end of the column. This works similar to the way that " Refx " works for the left vertical brace.
Connection cut width ( cut width ): Same as " Connection cut width " for the left brace, except that this applies to the right brace.
Connection cut length ( cut length ): Same as " Connection cut length " for the left brace, except that this applies to the right brace.

Brace Connection To Gusset Wide Flange Flange Plate
( web-horizontal wide flange vertical braces, 2- or 3-point, flange gussets, to a column )
Hole pattern for field bolting the braces to the flange gussets
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-horizontal wide flange brace to the near-side and far-side flange gussets.
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 above, set the diameter of holes through the near-side and far-side flange gussets.
Rows: The total number of holes in any column of holes on the near-side flange gusset. The number of " Rows " entered here is also applied to the far-side flange gusset (see example ). Bolt row spacing on a web-horizontal wide flange brace flange gusset runs parallel with the work line of the vertical brace. For the brace shown in the example above, the number of " Rows " is ' 3 '.
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 row of holes on the flange gusset (see example ).
Hole spacing along brace ( rsp ): Row spacing. This is the distance (center to center) between of any two adjacent holes in the same column of holes on the flange gusset (see example ). This distance is measured 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 web-horizontal wide flange vertical brace's flange to the nearest hole in that brace's flange. See the example . The forward edge of the brace's flange is the edge that is closest to the work point of the vertical brace. Holes in the brace's flange are for field bolting to the flange gusset plates. This edge distance applies to both flanges of the brace.
Other edge distance along brace ( other ed ): The distance from the connection edge of the flange gusset plate to the nearest hole for field bolting that flange gusset plate to the flange of the web-horizontal wide flange vertical brace. See the example . This one edge distance applies to both flange gusset plates.
Columns: The number of columns of holes on the flange gusset (see example ). These holes are used for field bolting the flange of the brace to the gusset. Column spacing runs perpendicular to the work line of the web-horizontal wide flange brace. In the example above, the number of " Columns " is ' 2 '.
Distance to 1st hole perpendicular to brace ( perp ): The distance from the work line of the vertical brace perpendicular to the nearest column of holes. In the example above, this distance would be half the " Hole spacing perpendicular to brace " since the work line of the brace is centered between the two columns of holes.
Hole spacing perpendicular to brace ( csp ): 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 web-horizontal wide flange brace.
