Brace Connection To Gusset Hss Paddle " connection design locks
| An HSS, pipe or tube horizontal brace's paddle plate shop bolts to a gusset plate at a beam-column-beam corner per " Brace Connection To Gusset Hss Paddle " locks. Depending on the framing situation, the gusset may field bolt directly to either beam's flange, or it may field bolt with clip angles to either beam's web. The paddle plate to brace connection " Weld length " controls the notch length in the HSS brace.

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.

Brace Connection To Gusset Hss Paddle
( HSS, pipe or tube brace to a beam-column-beam corner )
Paddle plate
Length: The length of either of the two edges of the paddle plate that are parallel with the work line of the horizontal brace. See the example .
Width: The width of the forward edge of the paddle plate. Since the paddle plate is rectangular, this is also the width of the interior edge of the paddle plate. This dimension is perpendicular to the work line of the horizontal brace. See the example .
Plate thickness ( not depicted ): The " Material thickness " of the paddle plate. Increasing the " Plate thickness " moves the bottom surface of the paddle plate down, while the top surface remains at the same elevation, flush to the bottom face of the gusset. The near-side and far-side " Notch width " in the brace material is updated automatically. See the example .
Refx: The distance from the forward edge of the paddle plate to the work point of the brace. Tip: To get a properly designed connection, the " Minus dimension " ( "
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 paddle plate (the length edge is parallel with the work line). Changing the " Refy " slides the paddle plate sideways (moves it perpendicular to the work line) -- it does not move the holes in the plate since hole placement is set on the gusset plate.
Paddle to brace connection (shop welded)
Weld size ( not depicted ): The weld size for shop welding the paddle plate to the brace. Weld is placed along the NS and FS notches in the brace.
Weld length ( not depicted ): The length of the welds along the notches in the NS or FS of the horizontal brace. Assuming that the related lockable fields are unlocked (
Paddle to gusset connection (shop 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 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 through which the brace will be bolted to the gusset plate in the shop.
Rows: The number of holes in any one column of holes. Row spacing on a paddle plate runs parallel with the work line of the horizontal brace. 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 brace's work point to the center of the nearest row of holes in the paddle plate. See the example .
Hole spacing along brace ( rsp ): Row spacing. This is the distance (center to center) between any two adjacent holes in the same column of holes. Row spacing on an HSS brace's paddle plate runs parallel with the work line of the horizontal brace. See the example .
End connection failure message: Invalid bolt spacing
Edge distance along brace ( ed ): The distance from the forward edge of the paddle plate to the nearest hole in the paddle plate. The paddle plate's forward edge is the edge that is closest to the work point of the HSS horizontal brace. Holes in the paddle plate are for bolting the paddle plate to the gusset plate. See the example .
Other edge distance along brace ( not depicted ): The distance from the edge of the gusset plate to the nearest hole for bolting the paddle plate to the gusset plate.
Columns ( cols ): The number of columns of holes for shop bolting the brace to the gusset plate. Bolt columns run parallel with the work line of the 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 horizontal brace perpendicular to the nearest column of holes in the paddle 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 columns of holes in the paddle plate (see example ). Column spacing runs perpendicular to the work line of the horizontal brace.
Horizontal edge distance ( hed ): The distance (perpendicular to the work line of the horizontal brace) from the length edge of the paddle plate to the nearest column of holes for shop bolting the paddle plate to the gusset plate. See the example .
