摘　　要：木结构剪力墙是轻型木结构中最重要的竖向抗侧力体系。由于受实验条件的限制,从木剪力墙抗侧性能的试验研究中不可能获得所有需要的结果。采用有限元软件ANSYS对某一常规做法的木结构剪力墙进行的侧向单调加载分析,得到了试验中较难得到的木构架与覆面板的应力分布,且所得的荷载-位移曲线较好地模拟了试验曲线。Wood shearwalls are most important vertical lateral load resisting systems. Not all of the required results of wood shearwalls can be obtained from experimental investigations due to some restrictions of test conditions. A static finite element analysis on the behavior of wood shearwalls with normal configuration under monotonic lateral loads was carried out using ANSYS. Stress distributions in framings and sheathings were presented which can not be easily obtained from experimental research. Lateral load-deflection curve rsulted from ANSYS analysis agrees well with the curves from tests.
