Structural Testing of Steel Deck Diaphragm Assemblies

Year: 2018

Industry Participants: Prescient Co. Inc., J. R. Harris & Co., Ramtech Labortories,听 Hilti Corp.

Primary Investigator:听Dr. Brad Wham

Summary:听Structural 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 exceeding听卤 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.听
