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, timber & aluminium design codes. It can make use of various forms of
analysis from the traditional static analysis to more recent analysis methods
like p-delta analysis, geometric non-linear analysis, Pushover analysis (Static-NonLinear Analysis)
or a buckling analysis. It can also make use of various forms of dynamic analysis methods
from time history analysis to response spectrum analysis. The response spectrum analysis
feature is supported for both users defined spectra as well as a number of international code specified spectra.
As the name suggests STAAD stands for Structural Analysis And Design. Designs can be building
structures, culverts, petrochemical plants, tunnels, bridges and piles. STAAD Pro helps
structural engineers automate their tasks by removing the tedious and long procedures of the manual methods.
