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...

Scaling Factor for Basic Load Cases

The ability to apply a scaling factor to an entire Basic Load Case in the Basic Load Case spreadsheet is now available in RISA-3D v19. These scaling factors give the user the flexibility and freedom to modify and manipulate the loading conditions in the model.

Orthotropic Plates in RISA-3D

RISA-3D Version 19 now includes the ability to define the plate methodology of a material as orthotropic. In structural analysis and design, it may be useful to define plates or slabs that have different characteristics (stiffness) in the longitudinal and transverse directions. Doing so will result...

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...
