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.[1][2]

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.

​

Processor: Intel® Pentium or AMD® processor 3.0 GHz or greater.

​

Memory: 1 GB minimum, 2 GB recommended (4GB for STAAD.Pro Advanced). More memory almost always improves performance, particularly when working with larger models. 4 GB (8 GB for STAAD.Pro Advancd) or more can help speed up solutions for very large complex models with large numbers of load cases.

​

Hard Disk: Requirements will vary depending on the modules you are installing. A typical minimum is 500MB free space.

​

VideoGraphics:  Bentley strongly recommends avoiding onboard graphics chips in favor of a discrete GPU from the nVidia GeForce or Quadro range with at least 128-bit bus and 1 GB of RAM, or equivalent solution from ATI/AMD.
