CSI Bridge 25.3.1 (2826)

Computers and Structures, Inc. (CSI) is pleased to announce the availability of CSiBridge 25.3.1 (2826). This update adds a comprehensive calculation report for IRC 112-2020 column service checks and now includes the AASHTO 2020 9th Edition automated bridge wind loading.

CSiBridge v25.3.1 Enhancements - Date: 11-Jun-2024

10693 The version number has been changed to v25.3.1 for a new minor release.
Incidents Resolved
10695 An incident was resolved where the program could terminate unexpectedly when drawing a special joint or while drawing other object types in a window where joint objects were set to be visible. This issue only affected v25.3.0. Special joints could still be added using the database, other objects could be added through the database or on screen by turning off the visibility of joints in the window.


CSiBridge is specialized analysis and design software tailored for the engineering of bridge systems. Suspension, cable-stay, elevated-roadway, and other types of bridge systems may be modeled and designed to suit any one of a variety of purposes, including means for crossing water, linking points between shear terrain, or extending over highway infrastructure. Customized controls and features integrate across a powerful object-based modeling environment to offer an intuitive, practical, and productive computational tool for bridge engineering. 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.
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, AASHTO LRFD design is included with automated load combinations, superstructure design and the latest seismic design.
