Description

This presentation describes the seismic design of concrete-filled steel deck diaphragms based on the latest research. Design equations in the latest (and in some cases upcoming) code editions along with supporting research will be presented for the two basic limit states of diagonal tension cracking and shear transfer failure. An example will be provided to demonstrate the design of a concrete-filled steel deck diaphragm for these limit states using demands calculated with the alternative diaphragm design provisions in ASCE 7. Calculation of diaphragm deflections and design of shear transfer along collectors will also be discussed. The presentation will conclude with a description of how buildings will perform during earthquakes if designed using these approaches.

Course will award 1.5 hours of continuing education
This course is Diamond Review approved in 49 states. New York does not accept hours from recordings.

Please note: This webinar is part of the Seismic Design Series and is not included in the NCSEA Webinar Subscription.
