The Cold-Formed Steel Engineers Institute (CFSEI) will host a webinar on “Design Considerations for Cold-Formed Steel Light Frame Diaphragms” on Thursday, April 9, 2020 from 3:00 p.m. to 4:30 p.m. EDT. The webinar is designed for architects, engineers, building officials and contractors. Participants are eligible for 1.5 PDHs.

The webinar will cover the basic design of cold-formed steel light frame diaphragms as envisioned in the provisions articulated in AISI S100-16, North American Specification for the Design of Cold-Formed Steel Structural Members, 2016 Edition; AISI S230-19, North American Standard for Cold-Formed Steel Framing―Prescriptive Method for One- and Two-Family Dwellings, 2019 Edition; AISI S400-15 w/S1-16, North American Standard for Seismic Design of Cold-Formed Steel Structural Systems, 2015 Edition with Supplement 1; and AISI S240-15, North American Standard for Cold-Formed Steel Structural Framing, 2015 Edition.

Design practice documents derived from these AISI standards will also be addressed. At the conclusion of the webinar, design professionals will have a better understanding of current provisions that support engineered design (strength and deflection) of conventional code-based light frame cold-formed steel diaphragms as well as the limitations of these provisions.

The webinar will be conducted by Reynaud Serrette, Ph.D., a professor in the Department of Civil, Environmental and Sustainable Engineering at Santa Clara University in Santa Clara, California. Dr. Serrette has been involved in cold-formed steel research and design since 1987.
