Location
Girder: Specify the girder(s) for which the bracing will be generted.
Skew Angle: Define the skew angle for the bracing.
Station: Enter the station along the PGL. for the bracing to be generted.
Sections
Section: Assign a section to the bracing. A section can either be imported or selected from the previously defined ones under Properties > Sections.
Orientation Angle: Define the orientation angle for the bracing.
Chord Offset
Reference Edge [Top of Web/Bottom of Web]: A reference edge can be selected using this parameter. The selected edge directly influences the 3D model and FEM analysis by applying the bracing rigidity to either the top nodes or bottom nodes of the web. Refer to the screenshots below for additional clarification.
Chord - Vert. Offset from Ref. Edge :Based on the selected reference edge, a vertical offset value can be specified to define the bracing location.
Chord - Horz. Offset from Center of Web: A horizontal offset value with respect to the web's center can be defined using this parameter.
Gusset Plate
The parameters listed below are exclusively used for 3D representation. "Gusset Plate" objects defined under the Properties tab can be assigned here. The gusset plates assigned in this section do not have FEM attributes but can be applied as weight loads if relevant definitions are made under the Construction section of the workflow, particularly in Girder/Crossframe Construction using the Stiffener Gusset Plate Load parameter.
Gusset Plate: A previously defined gusset plate can be assigned to the bracing using this parameter.
Horizontal Dist. between Web Edge and Plate Edge: The ditance of the gusset plate can be defined using this parameter.
Stiffener
The parameters listed below are exclusively used for 3D representation. The stiffeners modeled here do not have FEM attributes but can be applied as weight loads if relevant definitions are made under the Construction section of the workflow, particularly in Girder/Crossframe Construction using the Stiffener Gusset Plate Load parameter.Refer to the figure below for a visual representation of each parameter.
Stiffener Used [YES/NO]: This parameter determines whether further stiffener-related parameters are applicable. Selecting "NO" will make the parameters below display as "Not Applicable (N/A)." Selecting "YES" allows further definitions related to crossframe stiffeners.
Vertical Stiffener Thickness: This parameter can be used to adjust the thickness of the stiffeners in the longitudinal direction.
Vertical Stiffener Width: This parameter allows you to adjust the width of the vertical stiffeners.
Vertical Distance from Top of Web: This parameter can be used to define an offset value for the stiffeners from the top of the web.
Vertical Distance from Bottom of Web: This parameter can be used to define an offset value for the stiffeners from the bottom of the web.
Top-Inner Chamfer: This parameter defines the chamfer value for the inner section of the stiffeners' top side.
Top-Outer Chamfer: This parameter defines the chamfer value for the outer section of the stiffeners' top side.
Bottom-Inner Chamfer: This parameter defines the chamfer value for the inner section of the stiffeners' bottom side.
Bottom-Outer Chamfer: This parameter defines the chamfer value for the outer section of the stiffeners' bottom side.
Material: This parameter allows a material to be assigned to the stiffener. Materials can either be imported or selected from previously defined materials under Properties - Materials.
FEA
Axial Rigidity Coefficient: This parameter can be used to define the axial rigidity of the bracing.
