Geometric information about the superstructure is defined on this tab.

‍NOTE: In XBRate, the superstructure is considered to be everything above the lower cross beam.

General

Item	Description
Pier Type	Select the pier type. Choices are Continous, Integral, and Expansion.

Continous piers have a superstructure moment connection across the pier, but superstructure moments are not transmitted to the pier Integral piers have a full moment connection between the superstructure and the pier. Expansion piers do not transmit superstructure moments across or into the pier.

‍NOTE: The schematic image updates to reflect the selected pier type
