The development of CSI software spans three decades, starting with the research of Dr. Edward L. Wilson at the University of California at Berkeley. The revolutionary SAP program was first released in 1970, and Dr. Wilson has subsequently been recognised by national and international engineering societies as one of the preeminent researchers in the field of computer aided structural analysis.
Each of CSI's programs is tailored to specific classes of structures, allowing the engineering community to work at more productive and efficient levels than are possible with "general purpose" type programs.
- SAP2000 is intended for use on civil structures such as bridges, dams, stadiums, industrial structures and buildings.
- ETABS has been developed specifically for multi-story building structures, such as office buildings, apartments and hospitals.
- SAFE System provides an efficient and powerful program for the analysis and design of concrete slabs and foundations.
- PERFORM 3D provides nonlinear analysis and performance assessment for 3D structures.
- CSiCOL is a comprehensive software package used for the analysis and design of columns.
Not only is CSI known for analytically sophisticated software, but for unsurpassed product support as well. User support activities include advice on structural systems, interpretation of structural behavior, clarification on various aspects of building codes, and opinions on special modeling problems and other subjects related to computerised structural analysis and design.
