How Do I Detach a Wall Panel From a Diaphragm?
The ability to detach a wall panel from a diaphragm was a feature added in RISA-3D V13.

How can I transfer my slab design from RISAFloor ES onto drawings?
The ability of RISAFloor ES to design rebar for two way concrete slabs is powerful. Such designs are made much more powerful when they can easily be conveyed on construction drawings.

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...

What is a Semi-Rigid Diaphragm?
RISAFloor Concrete Floor Slabs can design be transferred into RISA-3D for lateral design using either a Rigid Diaphragm or Semi-Rigid diaphragm. In RISA-3D, the wind and seismic loads are calculated and then applied into the diaphragm level to distribute the forces to the Lateral Resisting System.

How to Model With Stem Walls in RISAFoundation
New in RISAFoundation V7 is a Stem Wall element. This element would be drawn on a slab element for the purpose of transferring wall loads into the slab. You can add stem walls either from the Draw Stem Walls dialog.

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...
