Webinar on Design Considerations for Cold-Formed Steel Light Frame Diaphragms


This 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 this webinar, design professionals will have a better understanding of current provisions that support engineered design (strength and deflection) of conventional codebased light frame cold-formed steel diaphragms as well as the limitations of these provisions.
