Utilizing RISA-3D for Seismic Design of Concrete Walls
In RISA-3D we now have the ability to design concrete shear walls for seismic forces.
With RISA’s latest release of RISA-3D v23.0.1, we’re continuing to expand support for IBC 2024, helping engineers stay aligned with the latest building code requirements as adoption accelerates across the U.S.—including federally funded projects. This release builds on v23.0.0 ASCE 7-22 enhancements and adds key material design updates that move RISA further into full IBC 2024 compliance. New Material Design Updates Supporting IBC 2024 The upcoming release introduces several important design code updates referenced by IBC 2024, including: Steel Seismic design per AISC 341-22 Prequalified connections per AISC 358-22 Continued support for AISC 360-22 (16th Edition) steel design Ongoing updates to the hot-rolled shape database, including compatibility with both 15th and 16th Edition steel manuals These updates support modern seismic detailing requirements and ensure consistency with current steel industry standards. Masonry Masonry design per TMS 402-22, aligning with the latest strength and serviceability provisions adopted by IBC 2024. Key updates include: Revisions to shear design equations, including clarified definitions of shear area as outlined in Table 4.4.5, improving consistency and transparency in shear capacity calculations. Updated strength reduction factors for flexure and combined flexure + axial. Unlike previous editions that used a fixed ϕ-factor of 0.9, TMS 402-22 introduces tension-controlled,…

You may now design a Brace to Column Base Plate Connection in RISAConnection v8. This connection type combines the original single column base plate with a gusset from a connected vertical brace member. The connection allows tapered or rectangular gussets that frame into either the column flange or...
In RISAConnection v8, you may now design a Knee Brace and Diagonal Brace with a tapered gusset plate. One of the greatest benefits is the decreased size of a brace gusset plate by manipulating the fold line location.
In RISA-3D we now have the ability to:
In RISA-3D, you can define a boundary condition as Fixed (reaction will be calculated) or Fixed, (reaction will NOT be calculated).
We are proud to introduce drastically improved solution times in RISAFoundation version 10.0. This version was updated to include multi-threading/parallel processing capability which will allow it to take advantage of multiple core processors which are becoming extremely common on the market today.
The BS EN 1992-1-1:2004+A1:2014 has been implemented in RISA-3D version 16.0 and RISAFloor version 12.0. To select this code for your design, simply open the Model Settings and under the Codes tab select BS EN 1992-1-1:2004+A1:2014 for concrete:
The new TMS 402-16 Masonry Code (formerly designated as ACI 530 and ASCE 5) have been added to RISA-3D v16.0, RISAFloor v12.0 and RISAFoundation v10.0.
An update to the Cold-Formed Steel Design Codes has been added to RISA-3D v16.0 and RISAFloor v12.0. Updated Codes include:
