"Gusset Plate" objects defined under the 'Properties' tab are assigned here.

Excerpt
nameSTG_Internal_CrossFrame

Location

Girder: Choose Specify the a girder that are connected by the cross framegirder for which the crossframe will be generated.

Skew Angle [deg]:: A positive skew value rotates the cross frame in a clockwise direction, while a negative skew value rotates it in a counterclockwise direction. It is important to remember that the cross frames are positioned at the specified station along a line perpendicular to the PGL, which is then rotated according to the entered skew value.

Station[ftStart/End]: Enter the station along the PGLThe station of the cross-frame can either be defined using the options Start/End or through a manual definition.

Sections

Top Chord Section - : Assign a section for the top chord, which can be imported from the AISC database by the users. The finite element representation is in the form of a truss.

Diagonal Chord Section : Assign a section for the top/bottom/diagonal diagonal chord, which can be imported from the AISC database by the users. The finite element representation is in the form of a truss.

Bottom Chord Section: Assign a section for the bottom chord, which can be imported from the AISC database by the users. The finite element representation is in the form of a truss.

Gusset Plate

The parameters listed below are exclusively used for 3D representation.

Info
Note

However If "Stiffeners Load" is applied in the girder construction object, you can see the effect of gusset plate objects, along with stiffeners, as point loads acting on the girder top flanges during the load stage.

Top Gusset Plate:

Bottom Gusset Plate:Top Gusset Plate: Assign a previously defined gusset plate to the topside.

Bottom Gusset Plate: Assign a previously defined gusset plate to the bottom side.

Center Gusset Plate: Assign a previously defined gusset plate to the center plate.
