STAAD Pro is a software program used for structural analysis and design. It can be used to analyze and design buildings, bridges, towers, and other structures.

Performs structural analysis for static, dynamic, wind, earthquake, thermal, and moving loads.
Automates load calculations for gravity, wind, earthquakes, snow, and vehicles.
Supports international design standards for multiple countries, including the U.S., Europe, India, China, and Japan.
Offers advanced visualization tools with an intuitive user interface.

STAAD Pro, short for Structural Analysis and Design Program, was originally developed by Research Engineers International and later acquired by Bentley Systems. It is a widely recommended software for structural analysis and design, streamlining the BIM workflow by automatically converting physical models into analytical models for efficient analysis and design
