STAAD or (STAAD.Pro) is a structural analysis and design software application originally developed by Research Engineers International in 1997. In late 2005, Research Engineers International was bought by Bentley Systems.
STAAD.Pro is one of the most widely used structural analysis and design software products worldwide. It supports over 90 international steel, concrete and timber design codes.
It can make use of various forms of analysis from the traditional static analysis, p-delta analysis, geometric non-linear 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.
Additionally, STAAD.Pro is interoperabe with applications such as RAM Connection, AutoPIPE, SACS and many more engineering design and analysis applications to further improve collaboration between the different disciplines involved in a project. STAAD can be used for analysis and design of all types of structural projects from plants, buildings, and bridges to towers, tunnels, metro stations, water/wastewater treatment plants and more.
