What’s New in ASCE 7-22?

The ASCE/SEI 7-22 Minimum Design Loads and Associated Criteria for Buildings and Other Structures introduces significant updates from ASCE 7-16. The most notable changes impact wind and seismic provisions, along with new load combination rules that directly affect structural analysis and design. With the release of RISA-3D v23, engineers can now take advantage of these updates directly within their workflows. Why This Matters for Engineers? The most impactful provisions of ASCE 7-22 — wind, seismic, and load combinations — are now supported in RISA-3D v23, ensuring your projects remain compliant with the latest building codes and IBC 2024 adoption. Download the latest versions of RISA that supports ASCE 7-22 below. 1. Wind Provisions Key changes in ASCE 7-22 affect wind speed maps, velocity pressure equations, and roof zone definitions. Topic ASCE 7-16 ASCE 7-22 Design in RISA Wind Speed Maps Based on 2016 hurricane data Updated hurricane & transition zone maps RISA-3D generates wind loads per ASCE 7-22, reflecting updated maps Velocity Pressure (Kd) Included directionality factor Kd removed Automatically handled in RISA-3D wind load generation Roof Zones Based on h/B ratio for hip roofs h/B removed; new GCp values and roof zoning RISA-3D applies updated coefficients for accurate roof…
