 What's New in Version 8
With Version 8 you’ll enjoy up to 100X faster solutions with the new accelerated sparse solver. This version includes the design of steel members per the AISC 13th Edition steel code (both ASD & LRFD) and wood members per the NDS 2005 code.
 Overview
The one that started it all, RISA-2D is general purpose two-dimensional analysis and design software that makes engineering 2D structures quick and easy. RISA-2D’s powerful graphical modeling capabilities, flexible generation tools and detailed proprietary spreadsheets help you rapidly model, solve and optimize structures with any combination of materials.
Why RISA-2D Stands Apart
 A State-of-the-Art 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-2D, you can rapidly design frames, trusses, continuous beams, walls and everything in between.

 Interactive Modeling
The strength of RISA-2D is its truly interactive interface. With model editing, solving and results browsing in the same interface, you’re able to do real-time error checking of your data, and rapidly create, solve, modify and optimize your model.
 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.
