Abstract
A simple numerical model to predict the load-displacement response and ener gy dissipation characteristics of wood shear walls under general quasi-stat ic cyclic loading is presented. In this model the shear wall is composed of three structural components: rigid framing members, linear elastic sheathi ng panels, and nonlinear sheathing-to-framing connectors. The hysteretic mo del for the sheathing-to-framing connector takes account of pinching behavi or and strength and stiffness degradation under cyclic loading. A robust di splacement control solution strategy is utilized to predict the wall respon se under general cyclic loading protocols. The shear wall model has been in corporated into the computer program CASHEW (Cyclic Analysis of SHEar Walls ). The predictive capabilities of this program are compared with monotonic and cyclic tests of full-scale wood shear walls. It is shown that this mode l can accurately predict the load-displacement response and energy dissipat ion characteristic of wood shear walls under general cyclic loading. As an application of the CASHEW program, a procedure is presented for calibrating a single degree-of-freedom system to predict the complete nonlinear dynami c response of sheer walls under seismic loading.
