Several significant updates have been added to the new edition of Minimum Design Loads and Associated Criteria for Buildings and Other Structures, Standards ASCE/SEI 7-16.
The recently released document helps determine design loads including dead, live, soil, flood, tsunami, snow, rain, atmospheric ice, earthquake, wind, and fire, as well as how to assess load combinations. This new edition of ASCE 7 supersedes ASCE/SEI 7-10.
Significant changes include:
- New seismic maps reflecting the updated National Seismic Hazard Maps
- New wind speed maps, including new Hawaii maps, that result in reduced wind speeds for much of the United States, clarified special wind study zones, and separate Risk Category IV from Category III
- New snow load maps incorporating regional snow data for areas that previously required site-specific case study zones
- Updated rain duration provisions that align design requirements with International Plumbing Code provisions for drainage
- Entirely new chapter covering tsunami design provisions, which are important to Alaska, Hawaii, California, Oregon, and Washington
- New appendix provisions for fire design
Structural engineers, architects, and those engaged in preparing and administering local building codes should consult the updated code. To purchase online, visit the ASCE Bookstore.
