WEBINAR: Design of Cold-Formed Steel Buildings in RISA

More and more, commercial buildings are being designed as combined-use structures that handle everything from parking and retail, to apartments and other living spaces. With these requirements, structural engineers are asked to provide a safe, strong and non-combustible framing system that can also...

Exclude Results based on Selection in RISAFloor and RISAFoundation

New to RISAFloor and RISAFoundation is the ability to exclude results by selection. Excluding results from your model is useful when there are certain elements whose results aren’t of interest to you. Removing this clutter from the results will enable you to concentrate on the elements you are most...

Cold Formed Steel Wall Design Now Available

Cold-formed steel framing is a durable, reliable and cost-effective option for low-rise and mid-rise building projects. With the release of RISA-3D Version 19 and RISAFloor Version 15, cold formed steel (CFS) walls are now available for analysis and design. Walls that have been designated as...

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...

Updated Shear Contribution for Concrete (Vc) per ACI 318-19

The new ACI 318-19 code has been implemented into RISA-3D v19, RISAFloor v15, and RISAFoundation v13. One of the biggest changes between the ACI 318-14 code and the ACI 318-19 code is the shear contribution provided by the concrete, Vc.

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...
