Diaphragm [SIG]
The Diaphragm object serves as a connection element between I-Girders . Both the FEM and 3D models are generated based on the parameter definitions listed below.
Diaphragm
Girders: Specify the girders for which the diaphragms will be generated.
Station on Girders (from Right End): Assume the right-hand side as the starting point for station definition when viewed up-station from the alignment.
Thickness: This parameter is used to specify the thickness of the diaphragm in the bridge’s transverse direction.
Material: Assign a material to the diaphragm. Materials can be selected from previously defined options or imported as needed.
Top Offset (from Bottom of Top Flange): For a visual representation, refer to the figure below.
Bottom Offset (from Top of Bottom Flange): For a visual representation, refer to the figure below.
IFC
Type: The IFC entity type for BIM export. Available options include:
IfcBeam (default)
IfcBridgePart
IfcElementAssembly
IfcMember
IfcBuildingElementProxy
Predefined Type: The IFC Predefined Type is specified using this parameter. Available options include:
DIAPHRAGM (default)
BEAM
GIRDER
CROSS_BRACING
USERDEFINED
NOTDEFINED
Parent [Bridge/Superstructure/Deck/Substructure/Foundation/Approach_Structure/Retaining_Structure]: The IFC Parent is specified using this parameter to define the hierarchy relationship in the IFC model.
Quantities
Rebar Density (per cubic yard): The density of reinforcing steel per cubic yard of concrete. Used to calculate the rebar weight based on the diaphragm volume.
Rebar Weight: The calculated rebar weight based on the rebar density and diaphragm volume. (Read-only)
Volume: The total volume of the diaphragm concrete. (Read-only)
Weight: The total weight of the diaphragm based on volume and material density. (Read-only)
