Shear Buckling Testing of Wood Sheathing Panels
The shear buckling of the sheathing panel is considered one of the possible failure modes of light-frame wood shear walls subjected to lateral loads. In general, the buckling strength of an orthotropic plate is sensitive to its boundary condition along all edges. In reality, each typical sheathing panel (1220 × 2440 mm) connects to a frame (studs and plates) through nails and the frame is fixed between two floors. However, the studs are pinned at two ends and free to bend in out-of-plane directions. The nail-based connections offer some fixity to the end of the panel strip and act like nonlinear springs with equal intervals. Therefore, the real boundary condition of the sheathing panel is intermittent nonlinear springs along all edges plus the out-of-plane bending stiffness of studs along the long sides of the panel. The shear buckling strength of sheathing panels with the real boundary condition is tested in this study under the pure shear force using a specially designed frame at the structural laboratory at the Department of Civil and Environmental Engineering, Western University. The critical shear forces are compared to the strength of sheathing-to-frame nails and the available theoretical equation introduced by CSA-O86 for calculating shear buckling of an orthotropic plate with simply supported boundary conditions.
