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 (

Gusset One Member Square
(L, WT, 2L or W horizontal brace to a beam's top flange)
Plate thickness ( not depicted ): The " Material thickness " of the gusset plate.
Width ( plate width ): The distance between the framing edge of the gusset plate and the edge of the gusset plate that is parallel and opposite to the framing edge (see example ). This distance is perpendicular to the work line of the supporting beam.
Length ( plate length ): The length of the framing edge of the gusset plate (the edge that welds to the beam flange -- see example ).Plate length is measured parallel with the work line of the beam.
Refx: The positive (+) or negative (-) distance (parallel with the supporting beam's work line ) from the work point of the horizontal brace to the corner of the framing edge of the gusset plate that this end of the horizontal brace points toward (this also happens to be the nearest corner -- see example ).A " Refx " of ' 0 ' aligns the corner of the gusset plate with the brace's work point. Entering a positive (+) distance moves the corner of the gusset plate parallel with the work line of the beam toward the opposite end of the horizontal brace. Entering a negative (-) distance moves the gusset plate parallel with the work line of the beam in the direction that this end of the horizontal brace points toward. Changing the " Refx " moves the plate only, not the holes on the plate.
Refy: The positive (+) or negative (-) distance (perpendicular to the framing edge of the gusset plate) from the work point for this end of the horizontal brace to the framing edge of the gusset plate (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. Changing the " Refy " moves the plate only, not the holes on the plate.
Connection cut width ( cut width ): The distance (perpendicular to the work line of the supporting beam) between the two corners of the connection edge of the gusset plate. The connection edge is the edge that the horizontal brace frames to (see example ). This distance is not the actual width of the connection edge, but the width of that edge as measured parallel with the depth of the supporting beam.
Connection cut length ( cut lngth ): The distance (parallel with the work line of the supporting beam) between the two corners of the connection edge of the gusset plate. The connection edge is the edge that the horizontal brace frames to (see example ). This distance is not the actual length of the connection edge, but the length of that edge as measured parallel with the framing edge of the gusset plate -- that is, parallel with the work line of the supporting beam.
Acute side clip cut width ( acute side cut width ): The distance (measured perpendicular to the work line of the beam) between the two corners of the acute-side clip cut. As the example shows, the gusset plate is divided into an acute side and an obtuse side by the work line of the brace. The acute side of the gusset plate is the side contained by the acute angle between the brace and the beam.
Acute side clip cut length ( acute side cut length ): The distance (measured parallel with the work line of the beam) between the two corners of the acute-side clip cut. As the example shows, the gusset plate is divided into an acute side and an obtuse side by the work line of the brace. The acute side of the gusset plate is the side contained by the acute angle between the brace and the beam.
Obtuse side clip cut width ( obtuse cut width ): The distance (measured perpendicular to the work line of the beam) between the two corners of the clip cut that is included in the obtuse angle at the intersection of the brace to the beam. As the example shows, the gusset plate is divided into an acute side and an obtuse side by the work line of the brace. The obtuse side of the gusset plate is the side contained by the obtuse angle between the beam and the brace.
Obtuse side clip cut length ( obtuse cut length ): The distance (measured parallel with the work line of the beam) between the two corners of the clip cut that is included in the obtuse angle at the intersection of the brace to the beam. As the example shows, the gusset plate is divided into an acute side and an obtuse side by the work line of the brace. The obtuse side of the gusset plate is the side contained by the obtuse angle between the beam and the brace.
Flat width ( flat ): The distance (perpendicular to the work line of the supporting beam) between the two corners of the flat edge. The flat edge has a 90 degree corner at the framing edge of the gusset plate and another corner at the obtuse side clip cut (see example ).
End distance ( end dist ): The distance (parallel with the work line of the supporting beam) from the point where the work line of the brace intersects the framing edge of the gusset plate to the corner of the framing edge of the gusset plate that this end of the horizontal brace points toward (the obtuse-side corner of the framing edge -- see example ).
Length acute side ( acute side ): The distance (parallel with the work line of the supporting beam) from the point where the work line of the brace intersects the framing edge of the gusset plate to the corner of the framing edge that is on the acute side of the brace. As the example shows, the gusset plate is divided into an acute side and an obtuse side by the work line of the brace. The acute side of the gusset plate is the side contained by the acute angle between the beam and the brace. In other words, the " Length acute side " is the length of the gusset plate's framing edge that is on the acute side of the brace.
