The primary objective of this project was to develop design provisions for the utilization of clip angles as bearing stiffeners in cold-formed steel floor assemblies. This report presents the results of 120 end-two-flange loading tests of typical floor configurations carried out to check and compare joist depth and thickness, clip angle thickness and in-line and offset loading
conditions.

The project developed a design methodology for the use of clip angle bearing stiffeners in cold-formed steel floor joist assemblies. These provisions are suitable for including in the proposed AISI Standard for Cold-Formed Steel Framing – Floor and Roof System Design (predictor equation) and the AISI Standard for Cold-Formed Steel Framing – General Provisions (offset
conditions). In addition, provisions for clip angle bearing stiffeners should be added to the AISI Standard for Cold-Formed Steel Framing – Prescriptive Method for One and Two Family Dwellings based on these results.
