Structural Analysis And Design :

STAAD-III, the world’s most powerful and popular structural analysis and design software is in use across the globe since 1980. Now it is available in the form of STAAD.Pro which consists of STAAD + STARDYNE +FEMkit + VisualDraw . STAAD.Pro is a comprehensive, general purpose software for integrated structural analysis and design.

STAAD.Pro may be utilized for analyzing and designing practically all types of structures – buildings, bridges, towers, transportation, industrial and utility structures.

STAAD.Pro implements the most modern technologies in today’s Computer-Aided-Engineering.

It unifies leading-edge graphics and visualization techniques with proven and time tested analysis and design. A live, unified database provides seamless integration across all mission critical application – from concept design/analysis to detail design, simulation and visualization.
