Bridge Bent Data Form

Bent properties specify the geometry and section properties of the bent cap and the bent columns. They also specify the base support condition of the bent columns. Bent properties are used in abutment assignments to the bridge object. The bent property allows specification of the connection between the abutment and the girders as either integral or connected to the bottom of the girders only. The bent property also allows specification of a single bearing line (continuous superstructure) or a double bearing line (discontinuous superstructure).

Use the Bridge Bent Data form to define the bridge bents.

Girder Support Condition options. Choose for the girder support to be Integral to the bent, or for the bent to Connected to the Girder Bottom Only.
