CSiBridge

Contact sales Engineer & Analyze

Parametric bridge analysis, design, and load-rating software from CSI -- defined using layout lines, spans, bearings, abutments, bents, hinges, and post-tensioning; includes the SAPFire analysis engine with staged construction, creep/shrinkage, cable tensioning, geometric/material nonlinearity, and AASHTO LRFD design code checks.

Hidden Pricing

3.0 /5 composite score

Situational -- purpose-built for bridge analysis with the same CSI OAPI automation layer (VBA/VB.NET/C#/C++/Python/MATLAB) shared with SAP2000 and ETABS, giving it genuine agent-driven scripting capability; but pricing is contact-sales only (RF1) with no self-serve purchase path, and CSI does not officially support third-party OAPI tools.
