The Bridge Modeler enables parametric definition of girder-type bridge systems. Users initiate high-level parametric modeling by defining span length, layout lines, cross section, and other geometric and structural specifications. The Bridge Modeler then assembles frame, shell, and solid objects, and connects them with link elements, to automatically create bridge objects. The Bridge Modeler expedites design by automatically generating, meshing, and analyzing complex bridge models. Templates are also available for several superstructure and substructure design checks.
Use CSiBridge to model a composite steel-girder bridge based on that from the LRFD Design Example, Steel Girder Superstructure Bridge (FHWA NHI-04-041).
