Seminar Description

Part 1 in this webinar series presents methods on how to determine the required thickness of a diaphragm based on serviceability and strength (in-plane and out-of-plane) requirements. Also presented are step-by-step procedures on how to determine in-plane diaphragm forces due to wind, general structural integrity, seismic, soil, transfer, anchorage, and connection forces based on the requirements of ASCE/SEI 7-22. Methods on how to determine collector design forces for buildings assigned to SDC C through F are also provided.
