" Gusset 2 Point " & " Weld Conn2 " connection design locks
A shared gusset for HSS, pipe or tube vertical braces to a beam can be designed for any " Pipe/tube end-fitting ." For a ' Welded ' end fitting, 0 or 1 or 2 holes are centered on the work line (not shown). The shared gusset may be for 2-point bracing (" Gusset 2 Point ") or 3-point bracing (not shown). A clip angle (" NS/FS Clip Conn2 ") can be used for a 2-point gusset-to-beam connection instead of " Weld Conn 2 ." |

User Defined Connections: Settings that are locked ( ) in the user defined connection file will automatically be locked on the member edit window. 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.
Vertical 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 2 Point
( HSS vertical braces to a beam )
Gusset plate dimensions and location
Plate thickness ( not depicted ): The " Material thickness " of the gusset plate material.
Width ( plate width ): The distance (perpendicular to the beam's work line ) between the two longest edges of the gusset plate (see example ). For a shared gusset to a sloping beam, this distance is perpendicular to the slope of the beam (that is, perpendicular to the framing edge of the gusset plate). For a non-sloping beam this distance is vertical.
Length ( plate length ): The length of the framing edge of the gusset plate (which welds to the bottom flange of the supporting beam in the example shown). For a shared gusset to a non-sloping beam, this is the horizontal distance (parallel with the supporting beam's work line ) between the two vertical edges of the gusset plate. For a shared gusset to a sloping beam, this distance is parallel with the slope of the beam.
Refy: The positive (+) or negative (-) distance (perpendicular to the supporting beam's work line ) from the work point of the vertical brace to the corner of the gusset plate's framing edge that is closest to the left end of the beam. In the example shown, the framing edge of the gusset plate is the edge that welds to the beam's bottom flange. For a shared gusset to a non-sloping beam, this distance is vertical. Changing the " Refy " moves the gusset plate perpendicular to the work line of the beam, but does not move the holes on the plate.
Left Brace [ member number ]
Refx ( refx left ): The positive (+) or negative (-) distance (parallel with the supporting beam's work line ) from the work point of the left vertical brace to the corner of the framing edge of the gusset plate that is closest to the left end of the beam (see example ). For a shared gusset plate to a non-sloping beam, this distance is horizontal. Changing the " Refx " moves the gusset plate parallel with the work line of the beam, but does not move the holes on the plate. To move the holes, change the entry made to " Distance to 1st hole along brace " under " Brace Connection To Gusset Hss Bolted " or " Brace Connection To Gusset Hss Paddle " or " Brace Connection To Gusset Hss Welded ."
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 vertical brace connects 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 depth of the beam.
Connection cut length ( cut len ): 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 vertical brace connects 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, as measured parallel with the beam.
Refx ( refx right ): The positive (+) or negative (-) distance (parallel with the supporting beam's work line ) from the work point of the right vertical brace to the corner of the gusset plate's framing edge that is closest to the right end of the beam. This works similar to the way that " Refx " works for the left vertical brace.
Connection cut width ( cut width ): see " Connection cut width " for the left brace.
Connection cut length ( cut length ): see " Connection cut length " for the left brace.

Weld Conn2
( HSS vertical braces, 2- or 3-point, to a beam )
Shop weld, gusset plate to the supporting beam
Weld size ( weld ): The weld size for shop welding the gusset plate to the supporting beam (see example ). Gussets for 2-point bracing can optionally be shop-bolted to the beam with a clip angle (" NS/FS Clip Conn2 "). 3-point gusset plates must be welded to the beam. Regardless of whether it is shop welded or shop bolted, the gusset will be detailed with the beam and field bolted to the vertical brace.
To get a weld (" Weld Conn2 "), select ' Welded ' for " Gusset to supporting member " under " Connection specifications " on the Vertical Brace Edit window.
To instead get a clip angle (" NS/FS Clip Conn2 "), select ' Clip Angle ' for " Gusset to supporting member ."
