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 Square
(angle horizontal brace to a beam web)
Plate thickness ( not depicted ): The distance between the two faces of the gusset plate.
Width ( plate width ): The distance (perpendicular to the work line of the supporting beam) from the framing edge of the gusset plate to the edge that is opposite to and parallel with the framing edge (see example ).
Length ( plate length ): The length of the framing edge of the gusset plate (the edge that welds to the beam web in the example shown). Plate length is measured parallel with the work line of the beam. Typically the length edge will be the longest edge of the gusset plate.
Refx: The positive (+) or negative (-) distance (parallel with the work line of the beam) from the work point for this end of the horizontal brace to the corner of the framing edge of the gusset plate that this end of the horizontal brace points toward (which also happens to be the nearest corner -- see example ). An " 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 workline of the beam toward the opposite end of the horizontal brace. Entering a negative (-) distance moves the gusset plate parallel with the workline 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 ( not depicted ): 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. 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 " Y-reference " moves the plate only, not the holes on the plate. For the example shown, in which the gusset welds to the beam web, the default " Refy " is half the web thickness. For a gusset that fastens with a NS and/or FS clip angle ("
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 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 workline 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 ( os 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 workline 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 length: 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 ). This distance is parallel with the work line of the supporting beam.
End distance ( end dist ): The distance (parallel with the work line of the supporting beam) from the point where the workline 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: The distance (parallel with the work line of the supporting beam) from the point where the workline 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 workline 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.

Brace Connection To Gusset

Bolt diameter ( not depicted ): The diameter of 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, together with the " Hole type " entered below, set the diameter of holes the bolts go into. 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 ("
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 for bolting the horizontal brace to the gusset plate.
Rows: The number of holes in the column of holes with the greatest number of holes. Bolt row spacing on a horizontal brace gusset plate runs parallel to the work line of the horizontal brace (see example ). For an angle horizontal brace with staggered holes, this is the number of rows of holes in the column of holes along the workline 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 brace shown in the example above, the number of " Bolt rows " is ' 4 '.
Distance to 1st hole along brace ( to 1st hole ): The distance (parallel with the work line of the horizontal brace) from its work point to the center of the nearest row of holes (see example ).
Hole spacing along brace ( row spacing ): The distance between the centers of 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 ( e 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 the material. This distance is measured parallel with the work line of the horizontal brace.
Columns: The number of columns of holes through the gusset plate. For the horizontal brace in the example above, the number of " Bolt columns " is ' 2 '. These bolts fasten the horizontal brace to the gusset. Bolt column spacing runs parallel with the work line of the horizontal brace. 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 clip angle ("
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 workline of the brace.
Hole spacing perpendicular to brace ( col 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
(angle horizontal brace to a beam web)
|
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.
In the example above, the gusset plate shop welds to the beam and will be detailed with the beam and field bolted to the brace. If the gusset were bolted to the beam with a clip angle, it would be detailed with the brace and field bolted to the beam.
