摘　　要：根据木结构剪力墙在水平力作用下的变形特点,将其水平位移分为三部分:钉节点变形引起的位移、覆面板剪切变形引起的位移和剪力墙整体弯曲变形引起的位移,通过对这三种位移的分别计算推导出了木结构剪力墙弹性刚度计算公式。然后,采用SAP2000建立了剪力墙的有限元模型,将有限元模型与本文推导公式的计算结果进行了对比,验证了计算公式的正确性。Based on the deformation of wood shear wall under lateral force, the lateral displacement could be divided into three parts ： the displacement coursed by nail slip, the displacement coursed by shear deformation of the sheathing panel and the displacement of shear wall bending. The formula of shear wall＇s elastic lateral stiffness was derived by calculating of these three displacements. At last, SAP2000 was used to set up finite element models of wood shear wall to calibrate the formula. Results showed that the displacement calculated by the formulas offered by this paper matched well with the numerical analysis results.
