Design of Back-to-Back CFS profiles now in RISAFloor
In many cases, cold-formed steel channels are built-up as back-to-back profiles in order to add strength and stability. Previously, these sections (along with face-to-face profiles) could be specified in RISAFloor, but unlike in RISA-3D could not be designed. RISAFloor v15 now includes the ability...

Interaction of Shear Forces Acting Along Orthogonal Axes in Concrete
Recent tests and analytical results for concrete columns have indicated that considering shear along each centroidal axis independently can be unconservative. Therefore current versions of RISA-3D, RISAFloor and RISAFoundation have included the consideration for the interaction of shear forces...

How Do Flexible Diaphragms Work on Sloped Roofs?
RISAFloor supports the use of flexible diaphragms on both flat and sloped roofs. Before reviewing the workflow for utilizing a flexible diaphragm on a sloped roof, it makes sense to review and understand the basic behavior of flexible diaphragms within RISAFloor. To do this, please first review the...
