Abstract
Abstract A shear resistant structural panel assembly for use in framed buildings comprising a facing of finish material bonded and having a lower tensile strength to a usually thinner, structural membrane having a higher tensile strength and directly fastened to structural framing elements by a series of shouldered fasteners applied through the shear panel along both its edges and within the field of the panel, said fasteners securing said structural membrane to the face of the structural framing elements at the bearing face of the shoulder to resist shearing and separation forces on said assembly. The preferred embodiment is a nail with a cone shaped ridge located below the surface of the nail's head at a depth sufficient to pin the sheet metal to the supporting structural frame. The bevel indents the sheet metal providing a broad bearing surface sa as to increase the tearout strength as well as preventing the sheet metal from lifting free of the framing element. Under cycled loading conditions the fastener provides a highly ductile joint which absorbs energy and dampens building oscillations reducing the loads on the building's structure.
