Abstract

This report describes the shear buckling and shear strain distribution of plywood used in wooden panel construction bearing walls. The purpose of the research was to confirm the affect of plywood shear buckling on shear strength, measure the shear stress distribution on plywood in detail through multipoint measurement, and clarify shear characteristics experimentally. The specimens were wooden glued panels with external dimensions of 1,000mm×1,000mm. The specimen parameters were plywood thickness (3.0, 5.0mm), bonding width (15, 30, 45mm). The test results confirmed the shear capacity and stiffness of the wooden panels decreased as a result of shear buckling of the plywood. The shear stress distribution was confirmed to show the same value before shear buckling occurs and that the stress distribution is non-uniform after buckling occurs. The ratio was confirmed to become larger as the shear deformation angle increased.
