Inclusion of RSA Results in RISAFoundation

With the release of RISAFoundation v13, you now have the ability to transfer Response Spectra Analysis reactions from RISA-3D v19. RISAFoundation now also includes additional seismic options that can be considered in the generation of Load Combinations.

Viewing Coordinates in Cursor Display

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. The mouse coordinates that are displayed are the coordinates of the grid point or joint that is nearest to the cursor. These are the same coordinates displayed in the Status Bar. If you would like to view the coordinates using your cursor then you can toggle this new feature by going to File-Application Settings and on the General tab check click the check box to Show current location coordinates next to cursor…

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 acting along orthogonal axes per ACI 318-19 equation 22.5.1.11. When Vu/ΦVn > 0.5 in both orthogonal directions, a new expandable section of the Detail Report will appear for the interaction equation. RISA-3D RISAFoundation…

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 lateral in RISAFloor will be transferred into RISA-3D when utilizing the Director feature. Currently, CFS walls are only available when the AISI S100-16: ASD or LRFD code is selected from the Model Settings. To draw CFS walls in RISA-3D, simply choose CFS from the Wall Material dropdown menu in the Properties Panel. The design for the CFS walls will follow the criteria assigned in the Design Rules. The Wall Design Rules may be modified through the Wall Design Rules spreadsheet, or through the Wall Definition Editor by selecting the ellipsis to the right of the Design Rule in the Properties Panel. CFS wall sheathing material options include Wood Structural sheathing, Steel Sheet sheathing, Gypsum board panels and Fiberboard. The sheathing material may be selected in the Wall Design Rules spreadsheet or within the Wall Panel Definition Editor. The program will design the optimal sheathing size based on the thickness requirements and shear demands. The Segmented…
