Description

Designers using the 2022 Edition of the ASCE/SEI standard Minimum Design Loads and Associated Criteria for Buildings and Other Structures (ASCE/SEI 7-22) will notice significant updates to seismic design of diaphragms and their chords and collectors: a new diaphragm design methodology added, an existing methodology expanded, significant changes affecting bare steel deck diaphragms, and more. To use ASCE 7-22 provisions, the designer will need to choose between three diaphragm seismic design methods and to incorporate other design updates. These updates are based on research and code development efforts that go back years, with contributions from research and guideline development teams and the NEHRP Provisions and ASCE 7 update participants. This presentation will provide a quick refresher the basics of diaphragm seismic design, will overview the three available diaphragm design methods, and will use examples to highlight details of the two newer diaphragm seismic design methodologies.

Course will award 1.5 hour of continuing education
