From concept to creation, every 3D FE model generated by the Steel Bridge Module brings with it decades of knowledge gained from working with top level engineers across the United States. From simple line girder projects to complex bridges featuring concentric girders with irregular spacing and variable deck width, the Steel Bridge Module provides the complete solution for steel girder bridges through its integration with LARSA 4D.
The Steel Bridge Module supports a variety of features allowing skew angles and support conditions for each abutment and pier, starting and ending girders at any point along the bridge, cross-slope, splice-points, cross-frames, lateral bracing, substringers, and modeling hybrid girders. With LARSA’s Bridge Path Coordinate System the user can create multiple bridge paths in the same file to define girders, spiral-on-and-off ramps and ground level footings.
As an integral part of the LARSA 4D BRIDGE Series, the Steel Bridge Module is included in the following packages of LARSA 4D.
