RISA-2D 8.0
What’s New
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.
Simple Structural Analysis Software Producing Powerful Results
RISA-2D is easy to learn, and powerful to use. With an intuitive interface and familiar spreadsheets, you can solve your next problem in minutes, not hours. Quickly analyze everything from simple beams and trusses to shear walls with openings. Break problems down to their basics and go.
Packed with the most current steel, concrete, cold-formed steel, and timber design codes, RISA-2D gives you the tools to tackle multi-material projects with confidence. Advanced features such as flexible design rules and a custom concrete Layout Editor allow the engineer to control the design, not just the program.
Review your results for the entire model graphically, or view member detail reports to see analysis results and design calculations (including sketches with rebar callouts) for each member.
RISA-2D In-Depth
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.
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.
