Description: Load-deflection characteristics and failure modes of urethane-foam-insulated, metal-clad, timber-framed and screw-fastened ceiling diaphragms are presented. Eight diaphragms, 2.44 m x 6.10 m, were built and tested as deep beams and another eight diaphragms, 2.44 mx3.66 m, were tested as short cantilever beams, primarily in shear. In-plane loads were applied to simulate wind loads carried by ceilings of farm buildings. Major variables include type of skin (steel versus aluminum), presence of foam (urethane foamed versus unfoamed panels), and density of urethane foam (32 and 48 kg/m3). The results are useful in incorporating diaphragm or stressed-skin principles into urethane foam insulated ceilings or walls of post or stud-wall building designs.

Keywords: structural characteristics of foam-insulated diaghragm panels
