CSiBridge is a state-of-the-art software product for the structural and seismic analysis, design, and rating of simple and complex bridges. All operations are integrated across a single user interface that provides an easy-to-use and intuitive workflow environment. Bridge models are created parametrically resulting in enhanced productivity, saving engineering time while redefining the standards of accuracy and versatility.
Advanced modeling features and sophisticated analysis techniques account for dynamic effects, inelastic behavior, and geometric nonlinearity. Code-based templates streamline the engineering process from model definition through analysis, design optimization, and the generation of comprehensive output reports. CSiBridge is the premier software for bridge engineering.
CSI Solvers have been tried and tested by the industry for over 35 years. The blazing fast SAPFire Analysis Engine can support multiple 64-bit solvers for analysis optimization and perform both Eigen Analysis and Ritz Analysis.
Bridges are easily modeled from geometry to loadings with Bridge Wizard. Modeling can also start with one of the many available bridge templates in the program.
Vehicle, seismic, and wind loading are generated according to building code (Eurocodes, AASHTO LRFD, Canadian, etc.) and assigned according to model geometry. A series of templates for assigning and enveloping load conditions make CSiBridge intuitive and practical.
Bents, abutments, restrainers, bearings and foundation springs can be easily modeled as either link or hinge elements.
Static-pushover and dynamic analyses (steady-state, response-spectrum, and time-history) provide further insight into earthquake resilience.
Comprehensive staged-construction sequence analysis that may consider time-dependent material properties, tendon and cable application with target-tensioning, and change in boundary/support conditions.
CSiBridge Load Rating features calculates the safe load capacity of a bridge based on the requirements of the AASHTO Manual.
