# Diaphragm \[STG]

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.
