Gusset One Member Perp " & " Brace Connection To Gusset " & " HB Conn2 "
| The gusset for an angle horizontal brace perpendicular to a beam's top flange is designed per " Gusset One Member Perp " locks. The brace field bolts to the gusset plate per " Brace Connection To Gusset " locks and shop welds to the top flange of the beam per " HB Conn2 " locks. A " Stagger bolts " hole pattern is shown in the example below, but angle braces can have other hole patterns.

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.

Gusset One Member Perp
( angle horizontal brace perpendicular to a beam )
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 measured 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 welds to the beam's top flange -- see example ). Plate length is measured parallel with the work line of the beam.
Refx: A positive (+) or negative (-) distance (measured 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 ). A " Refx " 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 normal, default value for this 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 (measured 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 (which welds to the flange or web of the beam -- see example ). A " Refy " 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.
Flat width ( flat wd ): 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 ). Flat width is measured parallel with the width of the gusset plate. Since the gusset plate is symmetrical around the work line of the brace, there is a flat with dimension on both sides of the gusset, and the entry made here applies to both of those flat widths.
Flat length ( flat ln ): The distance from the brace work line to the either corner of the edge of the gusset plate that is opposite to and parallel with the edge that frames to the beam. Since the work line of the brace cuts the gusset plate in half and the gusset is symmetrical across the work line, this length is one half of the actual length of that edge (see example ). Flat length is measured parallel with the work line of the beam.
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 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 ). 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.

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 ): 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. For an angle horizontal brace with staggered bolts, this is the number of rows of holes in the column of holes along the work line of the brace. For an angle brace with non-staggered holes, this is the number of rows in any single column of holes. Entering ' 0 ' removes the holes. For the example above, the number of " Rows " is ' 4 '.
Distance to 1st hole along brace ( to 1st hole ): The positive distance from the brace's work point to the center of the nearest hole. As shown in the example above, this distance is measured along the brace's work line.
Edge distance along brace ( edge dist ): 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 .
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 ). Bolt row spacing runs parallel with the work line of the horizontal brace.
End connection failure message: Invalid bolt spacing
Columns: The number of columns of holes in the gusset plate. These holes for field bolting the horizontal brace to the gusset. For the example above, the number of " Columns " is ' 2 '.
Distance to 1st hole perpendicular to brace ( not depicted ): The distance from the work line of the horizontal brace perpendicular to the nearest column of holes. In the example above, this distance would be ' 0 ' (zero) since the nearest column of holes aligns with the work line of the angle brace.
Hole spacing perpendicular to the brace ( sp ): Column spacing. 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.

HB Conn2
( shop weld, gusset to a beam's top flange )
Weld size ( weld ): The weld size used to shop weld the framing edge of the gusset plate to the top flange of the beam. This is also the weld size used to weld the under side of the gusset plate to the forward edge of the beam's top flange, which is shown with a blue dashed line ( - - - - - ) in the example . The gusset plate will be shop welded to (and detailed with) the beam and field bolted to the horizontal brace.
