Brace Connection To Gusset Hss Paddle " connection design locks
| A paddle plate end fitting for an HSS, pipe or tube vertical brace is designed per " Brace Connection To Gusset Hss Paddle " locks when ' Paddle plate ' is the selected " Pipe/tube end-fitting ." The paddle plate field bolts to the gusset plate, and the gusset plate shop welds to a column & base plate (shown) or to a column & cap plate (not shown).

User Defined Connections: Settings that are locked (

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.

Brace Connection To Gusset Hss Paddle
( gusset to column & base/cap plate )
Paddle plate
Thickness ( not depicted ): The " Material thickness " of the paddle plate. Since the thickness of the paddle plate is centered with respect to the work line of the vertical brace, increasing the " Thickness " adds material to both sides of the work line. The weld placement and " Notch width " in the vertical brace main material are updated automatically.
Width: The distance between the two corners of the forward edge of the paddle plate. The width of the plate is perpendicular to the work line of the vertical brace. See example .
Length: The length of either of the two edges of the paddle plate that are parallel with the work line of the vertical brace. See example . Increasing the " Length " extends the plate toward the opposite end of the vertical brace. The length of the weld and the " Notch length " in the vertical brace main material are updated automatically.
Refx: The distance from the end of the paddle plate to the work point of the brace. Tip: To get a properly designed connection, the " Minus dimension " ( "
Refy: The distance from the work line of the vertical brace to the length edge of the paddle 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 paddle plate. Changing the " Refy " slides the paddle 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. See the example .
Paddle 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, together with the " Hole type " entered below, set the diameter of holes in the stem plate and 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 below, set the diameter of holes for field bolting the stem plate to the gusset plate.
Rows: The total number of holes in any column of holes in the vertical brace stem plate to gusset connection (see example ). For the wide flange vertical brace shown in the example above, the number of " Bolt rows " is ' 5 '.
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 on the gusset plate (see example ).
Hole spacing along brace ( s ): 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 example ). Bolt row spacing on 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 ( edge dist ): The distance from the forward edge of the paddle plate to the nearest hole in paddle plate (see example ). The forward edge is the paddle plate edge that is closest to the work point of the HSS vertical brace. In other words, it is the edge that is closest to the column & base/cap plate. Holes in the paddle plate are for field bolting the paddle 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 bolting the paddle plate to the gusset plate (see example ).
Columns: The number of columns of holes on the gusset plate (see example ). For a ' Paddle plate ' or ' Welded tee ' end fitting, these holes are for field bolting the vertical brace to the gusset. For a ' Welded ' end fitting, these holes are for erection bolts . They run parallel with the work line of the vertical brace. 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 example above, this distance would be half the " Hole spacing perpendicular to brace " since the two columns of holes are centered around the work line of the brace.
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 vertical brace. Holes in an individual column run parallel with the work line.
Horizontal edge distance ( H ): The distance (perpendicular to the work line of the vertical brace) from the length edge of the paddle plate to the nearest column of holes for field bolting the paddle plate to the gusset plate. See the example .
