What’s New for IBC 2024 in RISA: A Closer Look

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,…

Modeling Cables in RISA-3D

One of the support questions we get most often is, “How can I model a cable element in RISA-3D?” Cables that are straight and experience only axial loading can be easily modeled. When modeling structures with cables (such as guyed structures) the cables can be modeled as tension only and doing so...

Governing Load Combinations for Shear in Concrete Columns

For concrete column members, the load combination producing the maximum shear code check is reported in the Detail Report and corresponding Results spreadsheet. Since concrete is evaluated based on a batch solution, this can be useful when shear governs the design.
