CSI ETABS
Integrated structural analysis and design software for multi-story buildings (steel/concrete frame, shear-wall, seismic, composite) on CSI's 64-bit SAPFire engine, sharing the CSI OAPI automation layer with SAP2000, SAFE, and CSiBridge.
Hidden Pricing
3.2 /5 composite score
Solid for multi-story building analysis and seismic design -- the CSI OAPI (VBA/VB.NET/C#/C++/Python/MATLAB, shared with SAP2000/SAFE/CSiBridge) is genuinely scriptable and has an active community Python wrapper on GitHub, but pricing is quote-only (RF1) and CSI does not support third-party OAPI tooling.
