• Summary:ÌýStructural assessment of cold-formed steel diaphragm assemblies was conducted in accordance with AISI S907. The cantilever-style tests were performed on 12 x 12 ft (3.7 x 3.7 m) square specimens and included both static and cyclic test protocols. Displacements exceedingÌý± 5 in. (12.7 cm) were applied to capture peak and residual strength of the joist/deck/fastener assembly, providing data relevant to system evaluation for seismically active regions.Ìý
