" Gusset One Member Perp " & " Brace Connection To Gusset " & " HB Conn2 "
The gusset for a W tee or wide flange or double-angle horizontal brace that is perpendicular to the beam it connects to is designed per " Gusset One Member Perp " locks. The brace bolts to the gusset per " Brace Connection To Gusset " locks. The " Gusset to beam connection " (' Welded ' or ' Clip angle ') is designed per " HB Conn2 " locks (or " NS/FS Clip Conn2 " locks) and sets whether the brace shop bolts or field bolts to the gusset. |

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 ( ). Related settings that are unlocked ( ) may be updated, and the " Left/Right end limit state " calculations will be updated. Settings that are locked ( ) will not be changed by connection design , even if doing so might prevent a connection failure.

Gusset One Member Perp
(WT, 2L or W horizontal brace to a beam's web or flange)
Plate thickness ( not depicted ): The " Material thickness " of the gusset plate.
Width ( plate width ): The distance from the framing edge of the gusset plate to the edge of the gusset plate that is opposite and parallel to the framing edge (see example ). Plate width is parallel with the work line of the horizontal brace and perpendicular to the work line of the beam.
Length ( plate length ): The length of the framing edge of the gusset plate (the edge that is welded in the example shown). Plate length is measured parallel with the work line of the beam.
Refx: A positive (+) or negative (-) distance (parallel with the work line of the supporting beam) from the work point of the horizontal brace to the corner of the framing edge of the gusset plate (see example ). An " X-reference " of ' 0 ' aligns the corner of the gusset plate with the brace's work point. Entering a negative (-) distance moves the gusset plate one direction parallel with the work line of the beam. Entering a positive (+) distance moves the gusset plate in the opposite direction parallel with the work line of the beam. The default setting is 1/2 the plate length since this type of gusset plate (disregarding the holes) is symmetrical around the work line of the horizontal brace.
Refy: A positive (+) or negative (-) distance (perpendicular to the work line of the supporting beam) from the work point of the horizontal brace to the framing edge of the gusset plate (the edge that is welded in the example shown). A " Y-reference " of ' 0 ' aligns the framing edge of the gusset plate with the work point. Entering a positive (+) distance moves the gusset plate away from the work point toward the opposite end of the horizontal brace. Entering a negative (-) distance moves the gusset plate in the direction that this end of the horizontal brace points toward. For the example shown, in which the gusset welds to the beam web, the default " Y-reference " is half the web thickness. For a gusset that fastens with a NS and/or FS clip angle (" NS/FS Clip Conn2 "), this distance is half the web thickness plus the thickness of the outstanding leg of the clip angle.
Flat width: The distance (perpendicular to the work line of the beam) from either corner of the framing edge of the gusset plate to where the plate begins to taper (see example ). Cut depth is measured parallel with the width of the gusset plate.
Flat length: One half of the length of the edge of the gusset plate that is parallel to and opposite to the framing edge of the gusset plate (see example ). Cut length is measured parallel with the work line of the beam. Since the gusset plate is symmetrical on either side of the brace work line, this distance is from the brace work line; consequently, the distance entered should be 1/2 the actual cut length.
Obtuse side clip cut width ( os cut width ): The distance (measured perpendicular to the work line of the beam) between the two corners of the clip cut that is on either side of the horizontal brace's work line (see example ). The gusset plate has no obtuse side or acute side since the brace frames perpendicular to beam. There is a clip cut on both sides of the gusset, and the entry made here applies to both of those clip cuts. The gusset plate is symmetrical around the work line of the brace,
Obtuse side clip cut length ( os cut length ): The distance (measured parallel with the work line of the beam) between the two corners of the clip cut that is on either side of the horizontal brace's work line (see example ).

There is a clip cut on both sides of the gusset, and the entry made here applies to both of those clip cuts. The gusset plate is symmetrical around the work line of the brace,

Brace Connection To Gusset
(WT, 2L or W horizontal brace to a beam's web or flange)
Bolt diameter ( not depicted ): The diameter of the bolts for the brace to the gusset plate. 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. The bolts are field bolts if the gusset welds to the web or flange. They are shop bolts if the gusset bolts to the web with a NS and/or FS clip angle (" NS/FS Clip Conn2 ").
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 any one column of holes. Bolt rows on a horizontal brace gusset plate run parallel with the work line of the horizontal brace (see example ).Entering ' 0 ' removes the holes. For 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 row of holes (see example ).
Hole spacing along brace ( rsp ): Row spacing. This 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 edge of the brace material that is nearest the brace work point to the center of the first hole in that same material. This distance is measured parallel with the work line of the horizontal brace. See the example .
Other edge distance along brace ( oed ): The distance from the edge of the gusset plate to the nearest hole for bolting the brace to the gusset plate. See the example .
Columns: The number of columns of holes in the gusset plate. For the example above, the number of " Columns " is ' 2 '. These holes are used for bolting the horizontal brace to the gusset.. The bolts are field bolts if the gusset welds to the web. They are shop bolts if the gusset bolts to the web with a NS and/or FS clip angle (" NS/FS Clip Conn2 ").
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 for bolting that brace to the gusset 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. This is the distance (center to center) between any two adjacent columns of holes (see example ). Bolt column spacing runs perpendicular to the work line of the horizontal brace. Holes within an individual column run parallel with the work line.

HB Conn2
(WT, 2L or W horizontal brace shop welded to a beam's web or flange)
You get " HB Conn2 " locks when ' Welded '' is selected for " Gusset to beam connection ." If ' Clip angle ' is selected, then leaf(s) named " NS Clip Conn2 " and/or " FS Clip Conn2 " become available instead of the " HB Conn2 " leaf. |
Weld size ( weld ): The weld size used to shop weld the framing edge of the gusset plate (both NS & FS) to the web of the beam or to a beam's flange. In the example above, the gusset plate shop welds to the beam, but if a gusset frames to a beam's web, you can optionally field bolt the gusset with a NS and/or FS clip angle (" NS/FS Clip Conn2 "). A clip angle is not an option if the gusset frames to a beam's flange. If the gusset shop welds to the beam web or flange, it will be detailed with the beam and field bolted to the brace. If the gusset bolts to the beam with a clip angle, it will be detailed with the brace and field bolted to the beam.
