STAAD or (STAAD Pro) is a structural analysis and design computer program originally developed by Research Engineers International at Yorba Linda CA in 1997. In late 2005, Research Engineers International was bought by a system.An older version called Staad-III for Windows is used by Iowa State University for educational purposes for civil and structural engineers.
The commercial version, STAAD.Pro, is one of the most widely used structural analysis and design software products worldwide. It supports several sheets of steel, concrete and timber design codes.
It can make use of various forms of analysis from the traditional 1st order static analysis, 2nd order p-delta analysis, geometric nonlinear analysis, Pushover analysis(Static-Non-Linear Analysis) or a buckling analysis. It can also make use of various forms of dynamic analysis from modal extraction to time history and response spectrum analysis.
