The bending and axial code checks for single angles differ somewhat from other shape types, because single angles behave quite differently in bending and compression depending on how they are braced along their length.
RISA-3D can design the Cold Formed Steel face-to-face channel and track sections. You can also get design of a Cold Formed Steel tube shape in RISA-3D. The Shape Selection dialog will allow you to model the built-up sections by selecting “Face to Face” shown below.
The new CSA O86-14 code has been implemented in RISA-3D v15.0 and RISAFloor v11.0
RISA-3D now supports hot rolled steel design for the Canadian market according to CSA S16-14.
These include:
In RISA-3D, RISAFloor, and RISAFoundation the cursor now provides additional information regarding the cursor coordinates. As you move your cursor around on your screen, a box adjacent to your cursor will appear and populate with the coordinates of the cursor.
In the RISA-3D when you model a WT brace it exists at the member centroid, which means that no bending ends up in the brace due to the fact that the brace is actually eccentric to the braced frame.
Seismic Forces are generated automatically using seismic parameters R, SD1, and SDS in the Seismic Load Generator when using the Director to go from RISAFloor to RISA-3D or when inserting Seismic Loads on a rigid diaphragm in RISA-3D. Additionally, Seismic Load Combinations can be generated using...
In a model that contains both RISAFloor and RISA-3D data it is possible to define your diaphragms as either flexible or rigid for lateral design. You can do this from the Diaphragms spreadsheet in either program:
