Tech Note J100-11: Cold-Formed Steel Floor Joists


Summary: Cold-formed steel (CFS) joists are becoming very popular where non-combustible material and long unsupported spans are required in design. The purpose of this Technical Note is to provide a review and summary of the AISI design requirements for cold-formed steel floor joists.

This Technical Note updates and replaces LGSEA Technical Note 552

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.
