Brace Connection To Gusset Hss Bolted " connection design locks
| An HSS, pipe or tube horizontal brace can be fitted with a built-up welded tee that field bolts to the brace's gusset plate per " Brace Connection To Gusset Hss Bolted " locks. The gusset can shop bolt to a beam's web (with a clip angle) or it can shop weld. It can shop weld to a beam's flange. To get connection design to create a gusset plate shaped like that in the example below, the brace needs to frame perpendicular to the beam.

User Defined Connections: Settings that are locked (
) in a user defined connection file will automatically be locked on a member edit window for which that file is the " Input connection type ." 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.
Horizontal Brace Edit: To change a setting, first set it to locked (
) may be updated, and the "

Brace Connection To Gusset Hss Bolted
(HSS, pipe or tube horizontal brace perpendicular to a beam's web or flange)
Stem plate
Thickness ( stem thickness ): The " Material thickness " of the stem plate. For a perfectly horizontal horizontal brace, increasing the " Thickness " moves the bottom surface of the stem plate down, while the top surface remains at the same elevation. See the example .
Width ( stem width ): The distance between the two corners of the forward edge of the stem plate. Since the stem plate is rectangular, this is also the length of the edge of stem plate that welds to the cap plate. The width of the plate is perpendicular to the work line of the horizontal brace. See the example .
Length ( stem length ): The length of either of the two edges of the stem plate that are parallel with the work line of the horizontal brace. See the example .
The " Minus dimension " ( refx ) under "
Refy ( not depicted ): The distance (perpendicular to the work line of the horizontal brace) from the work line of the horizontal brace to the length edge of the stem plate (the length edge is parallel with the work line). Changing the " Refy " slides the stem plate sideways (perpendicular to the work line) -- it does not move the holes in the plate since hole placement is set on the gusset plate.
Stem plate to cap plate connection (shop welded)
Weld size ( stem weld ): The weld size for shop welding the stem plate to the cap plate. This is labeled "stem weld" in the example .
Stem plate to gusset connection (field bolted)
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 bolts " list. The bolt diameter entered here also sets the diameter of holes the bolts go into.
Hole type ( not depicted ): Standard round or Short slot or Oversized or Long slot or User slot #1 or User slot #2 . This sets the type of hole to be used to bolt the horizontal brace and its gusset plate.
Rows: The number of holes in the column of holes with the greatest number of holes. Bolt row spacing on a horizontal brace gusset plate runs parallel with the work line of the horizontal brace (see example ). Entering ' 0 ' removes the holes. For the HSS 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 horizontal brace) from the work point to the center of the nearest hole (see example ).
Hole spacing along brace ( rsp ): Row spacing. The distance (center to center) between any two adjacent holes in the same column of holes (see example ). Row spacing runs parallel with the work line of the horizontal brace.
End connection failure message: Invalid bolt spacing
Edge distance along brace ( ed ): The distance from the forward edge of the welded-tee stem plate to the nearest hole in the stem plate (see example ). The forward edge is the stem plate edge that is closest to the work point of the HSS horizontal brace. Holes in the stem plate are for field bolting the stem plate to the gusset plate.
Other edge distance along brace ( oed ): The distance from the edge of the gusset plate to the nearest hole for bolting the stem plate to the gusset plate. See the example .
Columns: The number of columns of holes in the gusset plate. These holes are for bolting the horizontal brace to the gusset. Bolt column spacing runs perpendicular to the work line of the horizontal brace. For the example above, the number of " Columns " is ' 2 '.
Distance to 1st hole perpendicular to brace ( p ): The distance from the work line of the horizontal brace perpendicular to the nearest column of holes in the stem plate. 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. The distance (center to center) between any two adjacent columns of holes (see example ). Column spacing runs perpendicular to the work line of the horizontal brace.
Horizontal edge distance ( h ): The distance (perpendicular to the work line of the horizontal brace) from the length edge of the stem plate to the nearest column of holes for bolting the stem plate to the gusset plate. See the example .
Cap plate
Length ( cap length ): On a horizontal brace that is perfectly horizontal, this is the length of either of the vertical edges of the cap plate. See example .
Width ( cap width ): On a horizontal brace that is perfectly horizontal, this is the width of either of the horizontal edges of the cap plate. See example .
Plate thickness ( cap thickness ): The " Material thickness " of the cap plate. Increasing the cap plate " Thickness " moves the back face of the cap plate toward the opposite end of the horizontal brace, while the forward face of the cap plate remains the same distance from the work point. See example .
Refx ( not depicted ): The distance from the work line of the horizontal brace to the length edge of the cap plate. This distance is measured perpendicular with the work line of the horizontal brace. For a horizontal brace that is perfectly horizontal, this distance is measured horizontally. Changing the " Refx " slides the cap plate sideways.
Refy ( not depicted ): The distance from the work line of the horizontal brace to the top edge of the cap plate. This distance is measured perpendicular with the work line of the horizontal brace. For a horizontal brace that is perfectly horizontal, this distance is measured vertically. Changing the " Refy " slides the cap plate up or down.

Weld ( cap weld ): The weld size for shop welding the HSS, pipe or tube horizontal brace to the cap plate. This is labeled "cap weld" in the example .
