RISA 3D 

What’s New

The many new features we’ve added to Version 6 make it faster, more powerful and more intuitive than ever. Some of these new features are:

Overview

RISA-3D is so 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 and wood. It’s a tool no structural engineer should be without!

Why RISA-3D Stands Apart

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

Top-notch Presentation of Results
Both graphical and numerical visualization capabilities let you get presentation quality results quickly and easily.

Quality & Support
The support you receive from our staff of professional engineers is second-to-none. Our clients know they can rely on RISA for the dependable software and quality support they deserve.

Integrated Building Design:

RISAFloor and RISA-3D are so tightly integrated that they operate as one program on the same building model. Optimize the gravity system in RISAFloor and the lateral system in RISA-3D, with a free and complete flow of information both ways.

Use all the power of RISA-3D for your lateral system. Tension-only bracing, sloping columns, openings in walls, compression-only soil springs, are just a few of the possibilities. Even better, the RISA-3D and RISAFloor interfaces are the same, making them easier to learn.
