2020 CFSEI Virtual Expo – Basic Cold-Formed Steel Framing Diaphragm Design Examples

Part of Live Sessions – Aired on September 24, 2020

Continuing Education Credits Available – 1.5 PDH Credits

Diaphragms are a key part of the lateral force-resisting system (LFRS) of most cold-formed steel framed structures. Through design examples, this webinar will provide guidance for two types of diaphragm design: 1) Rigid diaphragm design for a simple one-story structure, and 2) Flexible diaphragm design of a one-story open-front structure. The design examples will focus on the diaphragm mechanics and transfer of forces to the vertical components of the LFRS (shear walls or X-braces). Design for both wind and seismic forces will be discussed.
