Tech Note L202-12: Diaphragm Design with Pneumatically Driven Pins


Summary: Wood based panels for shear walls and horizontal diaphragms have traditionally been attached to cold-formed steel framing using self-drilling, tapping screws. With the introduction of pneumatic nailing systems, wood based panels can now be fastened to steel in a manner similar to which panels have been nailed to wood framing in the past. Information on specifications, selection, and field inspection of pneumatic drive pins is contained in Technical Note F300-09. This Technical Note contains procedures for the design of floor and roof diaphragms over cold-formed steel framing using pneumatically driven pins.

Disclaimer: Designs cited herein are not intended to preclude the use of other materials, assemblies, structures or designs when these other designs demonstrate equivalent performance for the intended use. CFSEI documents are not intended to exclude the use and implementation of any other design or construction technique.
