The updated ASCE/SEI 7-22 Minimum Design Loads and Associated Criteria for Buildings and Other Structures includes the first-ever criteria for tornado-resistant design.
“We’re not designing tornado shelters with ASCE 7,” said J.G. (Greg) Soules, senior principal structural engineer for CB&I and vice chair of the ASCE 7-22 Committee, in a news release. “We’re simply designing for somewhat higher wind loads in certain regions of the country.”
The standard, updated every six years, provides up-to-date and coordinated loading provisions for general structural design. It prescribes design loads for all hazards including dead, live, soil, flood, tsunami, snow, rain, atmospheric ice, seismic, wind, and fire, as well as how to evaluate load combinations.
The new update draws on new models for more accurate snow loads and includes a new multipoint seismic spectrum for certain soft-soil sites. ASCE 7-22 now requires use of digital data identified in hazard-specific geodatabases for all environmental hazards.
