Ritz Vector Solver (Dynamics) now Available
RISA-3D v13 includes a new Ritz Vector Solver for the Dynamic analysis. When running a Response Spectrum analysis for seismic design, some structures experience large numbers of local modes that don’t contribute to the lateral response of the structure. The use of load-dependent Ritz vectors...

Moving Load Point Load Generator now Available
A common question we get in tech support is “how can I verify my moving load results?” We now have a feature that will allow you to quickly generate a static loading condition equivalent to the moving loads at any given step along their path so you can investigate the detailed results at this...

Cold-Formed Steel Back to Back Design
Cold Formed Steel channels are often built-up as back-to-back sections to help strengthen them. RISA-3D can design the Cold Formed Steel back-to-back channel and track sections. The Shape Selection dialog will allow you to model the built –up sections by selecting “Back to Back” shown below.

Canadian Wood Design now Available
Timber design per the Canadian CSA 086-2009 design code is now available. Canadian wood member design is very similar to the US NDS member design. There are slightly different load factors, material properties, shape tables, and capacity equations, but the overall modeling procedure in RISA is the...

Nesting Load Combinations
The Load Combinations spreadsheet in RISA-3D is limited to ten columns of BLC and Factor combinations. However, there are times where you may need to include additional entries to your Load Combination. To do this, you can simply “nest” your load combinations.
