Thank you, Ron. I'll look out for that announcement. Does anyone have an opinion either way about the IBC vs ASCE 7 approach to service wind? Using a fixed factor is simpler, but ASCE's MRI method ties the drift check to more tangible performace objectives. -- Christian Parker P.E., M.ASCE...
Christian, as you note the 0.42 factor in IBC is historic and ties back to ASD design. The ASCE 7 committee has not discussed updating this in IBC, but it could become a topic of discussion for the ASC 7-28 Committee, which will be formed in a few months. Look for a call for volunteers...
ASCE 7 has moved away from drift checks based on a fixed ratio of design wind loads. The motivation for this is understandable. As the commentary (Section CC1.2 in ASCE 7-10) suggests, different projects may have different risk tolerance for serviceability failure. For example, I am working...
Minimum Design Loads and Associated Criteria for Buildings and Other Structures, ASCE/SEI 7-22 provides the most up-to-date and coordinated loading provisions for general structural design. This standard prescribes design loads for all hazards including dead, live, soil, flood, tsunami, snow,...
