Defining Connections: Column to Beam Connections
Member Configuration The connection rule must be applied at the end of the beam (not the column).
While members (beams and columns) follow conventions tied to their local axes, interpreting results for wall panels, plate elements, and design strips requires a slightly different perspective. These elements deal with both in-plane and out-of-plane behavior, and the sign conventions can change depending on the program and axis orientation. Overview Table of Sign Conventions Element Type Positive Moment (M) Shear (V) Axial (P) Notes Wall Panels – In-Plane Compression in positive local-y face Downward on right face Tension = Positive Applies to in-plane forces only Wall Panels – Out-of-Plane Compression on positive local-y face N/A N/A Defines “positive bending” convention Plates (RISA-3D) Positive Mz = Top surface in compression Shear follows right-hand rule Tension = Positive Local Z-axis defaults upward Plates (RISAFoundation) Positive Mz = Top surface in compression Shear follows right-hand rule Tension = Positive Local Z-axis defaults downward Design Strips / Support Lines Sagging = Positive (bottom fiber in tension) Downward on right face Tension = Positive Matches slab design workflows Wall Panels Wall panels report forces in both in-plane and out-of-plane directions. In-plane: Axial = Positive tension Shear = Positive when downward on the right face Out-of-plane: Positive bending = compression on the positive local-y face of…

RISA-3D, RISAFloor and RISAFoundation allow users to create custom load combination sets by modifying and expanding the underlying XML file used by the Load Combination Generator. To learn more, review the video and article below:
One of the advantages of the RISA Building System is the ability to utilize and share model information (geometry, loading, etc.) between software packages. One such way, is the ability to define hot-rolled steel connections in RISAFloor and/or RISA-3D and then transfer them to RISAConnection for...

The latest release of the RISA-Revit Link now includes support for Autodesk Revit 2022 as well as the ability in import/export cold-formed steel wall panels. To learn more, watch the video below or check out the release notes.
In this video, learn about the various unbraced length parameters that exist in RISA-3D and how the different values can impact the design of beam and column members in RISA-3D. Click the button below, for more detailed information about unbraced length in RISA-3D.
RISA software is staying current with all the Windows updates in order to bring you the best quality that Windows recommends. Unfortunately, that means it will require a little extra time during installation and your computer could require a reboot more than once. The current versions of RISA...
The ability to design buckling restrained braced frames has been added to RISA-3D when you integrate your model from RISAFloor. In collaboration with CoreBrace, this new feature came as part of the release of RISA-3D v19.0.0 and RISAFloor v15.0.0.
