Abstract: In this study, an experimental study was conducted on the nailed timber-plywood-timber joints extended from the standard wall-floor joints of wooden light frame constructions, where the bottom plates of shear walls are nailed to the floors consisting of joists and floor sheathings nailed to them. The principal conclusions are as follows: The allowable lateral resistance of the nailed timber-plywood-timber joints can roundly be estimated by neglecting the plywood panels if their densities are higher than those of the timber main-members and they are fastened effectively onto the timber main-members. The stiffness of the timber-plywood-timber joints is less than that of the control timber-timber joints, which is improved by increasing the number of nails used to fasten the plywood panels onto the timber main-members. The stiffness of the joints whose floor sheathings are glued onto the joists is equivalent to the control timber-timber joints. The timber-plywood-timber joints with appropriate specifications have greater energy capacity until the failure than that of the control timber-timber joints. This ensures their energy capacity, which is important in dynamic resistance, to be equivalent to the control timber-timber joints.
