The latest version of ASCE 7 is the 2022 version which includes changes to the snow load provisions. This version of ASCE 7 is referenced in the 2024 version of the International Building Code (IBC) and International Residential Code (IRC). It is extremely important that truss technicians and truss designers understand these snow load changes, ensuring that the proper type of load (service level vs. ultimate) is being used in the truss design, as well as understanding how the ASCE 7-22 utilizes Risk Categories, Thermal Factors, and Winter Wind Parameters.
