Pier Model Type

Hi Rick,

Does the Pier Cap Dimensions and Column Layout in PGSuper model affect girder design? I am wondering if I should pick "Idealized" or "Physical" since I am not sure how it would affect my girder design.

Thank you!

The flexibility of the pier

The flexibility of the pier is modeled with using the "Physical" model. This will have some influence on the structural analysis for continuous structures. However, for WSDOTs policy regarding designing for the envelope of simple and continuous spans, the pier model type doesn't have any effect on the girder design. You may find some small effects for the negative moment analysis, depending on your pier/connection type.
