Portal Frame Design in RISA-3D
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,…

To select this code for your design, simply choose either LRFD or ASD from the Solution tab within the Global Project Settings. The addition of the new 15th Edition code, includes...
The most recent release of AISC 360-16 (15th Edition) includes changes to connection design for rectangular HSS shapes with applied concentrated forces. These changes are now included in RISAConnection v10.
The release of RISAConnection v10 incorporates updates according to AISC 360-16 (15th Edition) including changes to HSS provisions as well as improved design for column webs subject to out-of-plane loading, in addition to other enhancements.
Modeling tapered gusset plates in RISAConnection is now easier than ever. With the recent addition of the Custom Angle input, you may now enter an angle to quickly cut back a gusset edge.
Eurocode lateral torsional buckling capacity is calculated per equations in Annex F in the ENV 1993-1-1:1992. This calculation uses variables C1, C2 and C3. Since there is no generic formula in the Eurocode to calculate the moment gradient factor, C1, RISA will use the widely accepted López, Yong...
