Snow Loads in ASCE 7-22 and the Shift to Reliability-Targeted
Snow Loads

ASCE/SEI 7 Minimum Design Loads and Associated Criteria for Buildings and Other Structures is a nationally adopted loading standard for the analysis and design of buildings and other structures. The 2022 edition of this consensus standard has been adopted into the 2024 International Building Code. This presentation is intended to provide a brief overview of the significant changes to the snow loads in this important standard.

The snow provisions have been significantly revised in the 2022 edition of ASCE 7. This session will highlight the changes to the ground snow load maps, including the methodology for developing four new maps for Risk Category I, II, III, and IV, the new winter wind parameters, and more. This session will also include discussion of the new digital platform and webtool. The ASCE 7 Hazard Tool was developed to support the full version of ASCE 7-22 and free for all users; come understand how the Hazard Tool will be accessed and used.

Learning Objectives:

By the end of this session, participants will be able to:

• Summarize the major changes to the snow load sections of ASCE 7.
• Understand the new maps for multiple risk categories. 
• Know how to use the digital ASCE 7 Hazard Tool.
