CSi Bridge

CSiBridge is a state-of-the-art engineering tool for modeling, analyzing and design of bridge structures. With CSiBridge, the engineer can easily define complex bridge geometries, boundary conditions and load cases.

The bridge models are defined parametrically, using terms that are familiar to bridge engineers such as layout lines, spans, bearings, abutments, bents, hinges and post-tensioning. The software creates spine, shell or solid object models that update automatically as the bridge definition parameters are changed. CSiBridge design allows for quick and easy design and retrofitting of steel and concrete bridges.
 
The parametric modeler allows the user to build simple or complex bridge models and to make changes efficiently while maintaining total control over the design process. Lanes and vehicles can be defined quickly and include width effects. Simple and practical Gantt charts are available to simulate modeling of construction sequences and scheduling. The ease with which all of these tasks can be accomplished makes CSiBridge a versatile and productive software program.
 
Completely integrated within the CSiBridge design package is the power of the SAPFire® analysis engine, including staged construction, creep and shrinkage analysis, cable tensioning to target forces, camber and shape finding, geometric nonlinearity (P-delta and large displacements), material nonlinearity (superstructure, bearings, substructure and soil supports), buckling and static and dynamic analysis.
 
All of these apply to a single comprehensive model. In addition, Eurocode and AASHTO LRFD design is included with automated load combinations, superstructure design and the latest seismic design.
