How are Unbraced Lengths coordinated between RISAFloor and RISA-3D?
In a RISAFloor model the columns and beams can be assigned unbraced lengths, or the program may calculate them automatically. This unbraced length information can then be used in RISA-3D. A great example is the frame below:

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.

The Internal Force Summation Tool for Walls
You may be familiar with the Internal Force Summation Tool (IFST) that is currently present in RISA-3D. However, a new tool has been added which allows you to click point to point within a wall and will only sum forces between these two points. Previously when using the IFST, forces were summed...

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...

What do the Unbraced Length commands Segment and Lbyy mean?
Aside from leaving an unbraced length blank or inputting a fixed distance, you can harness the program’s ability to use a limited intelligence for determining unbraced lengths. In order to do this you can simply type in the name of the Unbraced Length Commands into the unbraced length field.
