The Caltrans BAG bridge-model generator has been largely replaced by the bridge modeler available to SAP2000 releases through Version 14, and the current CSiBridge. Since the Caltrans BAG generator, bridge modeling capabilities have greatly improved and expanded with the release of the bridge modeler. Parametric and template-based modeling features, powerful analysis processes, design optimization, and enhanced output formatting all combine to create a more productive product which is easier to use. Additional details may be found on the CSiBridge page of the CSI Website.
