Abstract: The subject diaphragms are made from individual corrugated sheets which are connected to one another and to framing members with discrete fasteners. Failure of them under load is most commonly due to localized bearing or shear failure at the fasteners. The shear stiffness of the diaphragms depends greatly on the layout and number of fasteners. Formulas are derived for the shear stiffness and for the fastener forces in such diaphragms, which should be applicable where bolts, rivets, screws, or welds are used as discrete fasteners, and where the diaphragm loads are in the working range. The formulas are shown to agree quite well with the results of previous tests by the writer.
