STAAD Pro.

STAAD Pro is a sophisticated software program used in civil and structural engineering to analyze and design structures. It is widely used in the design and analysis of various types of structures such as buildings, bridges, towers, tunnels, stadiums, and industrial structures.

The software provides a comprehensive and integrated environment for the modeling, analysis, and design of structural systems. It supports various types of analysis including linear and nonlinear static, dynamic, and modal analysis. It also supports different design codes and standards from around the world.

STAAD Pro allows engineers to create 3D models of structures using various elements such as beams, columns, plates, walls, and shells. The software provides a wide range of tools for modeling and editing these elements, including graphical user interfaces and advanced scripting capabilities. Engineers can also import 3D models from other CAD software and convert them into STAAD Pro models.
