RISA-3D Features

RISA-3D is popular among structural engineers for many reasons, but one in particular stands out: ease of use. We designed our premier product with the daily use of structural engineering professionals in mind.

User friendliness combined with advanced analysis capabilities make this industry standard software a very powerful tool for the analysis and optimization of all types of structures and all common structural materials, including steel, concrete, wood, aluminum and masonry. It’s a tool no structural engineer should be without!

No. 1 Software in the U.S.

A 2011 survey showed that RISA-3D was once again the most widely used software by engineers in the U.S.

State-of-the-Art Modeling Interface

Our multiple view interface, advanced selection and drawing tools, and spreadsheet features continue to be the best in the business.

Powerful Analysis and Design

With RISA-3D you can rapidly design buildings, bridges, racks, tanks, crane rails, stadiums, arenas, culverts, all types of industrial and commercial structures and everything in between.

Seamless Integration with RISAFloor, RISAFoundation & RISAConnection

RISA-3D's full integration within the RISA Building System enables you to manage all aspects of your project within the same environment.
