Based on the parametric definition, the Bridge Modeler creates a structural model for the analysis. The structural elements that are created (such as links representing the bearing, body constraints used for connection of the girder to the deck, etc.) vary depending on the deck section and model and are described in detail below.

Bridge AnalysisThe bridge modeler creates an object-based model through assembly of bridge components. Structural components are based on parametric definitions involving deck type and various bridge properties. For example, link elements represent bearings, body constraints represent girder-deck connections, etc. Additional element descriptions are as follows:
