Brace Connection To Gusset Hss Bolted " connection design locks
| A welded tee end fitting shop welds to an HSS, pipe or tube vertical brace when ' Bolted ' is selected as the brace's " Pipe/tube end-fitting ." Design of the welded tee and field bolting of the fitting to a gusset plate for a beam & column is done per " Brace Connection To Gusset Hss Bolted " locks. Each welded tee consists of a stem plate and a cap plate .

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.

Thickness ( stem thickness ): The distance between the near and far side faces of the stem plate. This is The " Material thickness " of the stem plate material. Increasing the " Thickness " moves the surface farthest from the gusset plate. See the left 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 stem plate is perpendicular to the work line of the vertical brace. See the example on the left.
Length ( stem length ): The length of either of the two edges of the stem plate that are parallel with the work line of the vertical brace. See example .
The " Minus dimension " ( refx ) under the "
Refy ( not depicted ): The distance from the work line of the vertical brace to the length edge of the stem plate (the length edge is parallel with the work line). This distance is perpendicular to the work line of the vertical brace in the same plane as the stem plate. 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
Weld size ( stem weld ): The weld size for shop welding the stem plate to the cap plate. This is labeled "stem weld" in the left example .
Stem Plate To Gusset Connection
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.
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 above, set the diameter of holes for field bolting the brace to the gusset plate.
Rows: The number of holes in any one column of holes. Bolt rows on a vertical brace gusset plate run perpendicular to the work line of the vertical brace. These holes are for field bolting the ' Bolted ' end fitting (welded tee stem plate) to the gusset plate. Entering ' 0 ' removes the holes. For the HSS vertical brace shown in the example above, the number of " Rows " is ' 5 '. If the brace is set for " Automatic minus dimension " and the stem plate " Length " is unlocked (
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 for fastening the stem plate to the gusset (see example ).
Hole spacing along brace ( spacing ): Row spacing. This is the distance (center to center) between of any two adjacent holes in the same column of holes on the gusset plate. See the right example , on which this dimension is labeled "spacing." If the brace is set for " Automatic minus dimension " and the stem plate " Length " is unlocked (
End connection failure message: Invalid bolt spacing
Edge distance along brace ( edge dist ): 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 vertical brace. Holes in the stem plate are for field bolting the stem plate to the gusset plate.
Other edge distance along brace ( other ed ): The distance from the edge of the gusset plate to the nearest hole for field bolting the stem plate to the gusset plate (see example ).
Columns: The number of columns of holes for field bolting the ' Bolted ' end fitting (stem plate) to the gusset. In 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 vertical 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 ( column spacing ): The distance (measured center to center) between any two columns of holes. Bolt column spacing runs perpendicular to the work line of the vertical brace. In the right example , this dimension is labeled "column spacing."
Horizontal edge distance ( hed ): The distance (perpendicular to the work line of the vertical brace) from the length edge of the stem plate to the nearest column of holes for field bolting the stem plate to the gusset plate. See the example .
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 back end of the vertical brace, while the forward face of the cap plate remains the same distance from the brace's work point. See the left example .
Width ( cap width ): The width of the cap plate is perpendicular to the work line of the vertical brace and in a plane that is parallel with the near-side surface of the gusset plate.. It is labeled as "cap width" in the left example .
Length ( cap length ): The length of the cap plate is in a plane that is perpendicular to the plane of the near-side surface of the gusset plate. It is labeled as "cap length" in the left example .
Refx ( not depicted ): The distance from the work line of the vertical brace to the length edge of the cap plate. This distance is perpendicular with the work line of the vertical brace in the same plane as the stem plate. Changing the " Refx " slides the cap plate sideways along the width of the stem plate.
Refz ( not depicted ): The distance from the work line of the vertical brace to the edge of the cap plate. This distance is perpendicular with the work line of the vertical brace and parallel with the length of the cap plate. Changing the " Refz " slides the cap plate parallel with its length. The default centers the cap plate with respect to the work line (the neutral axis) of the HSS brace.
Weld size ( cap weld ): The weld size for shop welding the pipe or tube vertical brace to the cap plate. This is labeled "cap weld" in the example .
