摘　　要：剪力墙是轻型木结构中重要的抗侧力构件,其抗侧性能受到众多因素影响,例如钉子的规格和间距、覆面板材的铺设方式及尺寸、是否有横撑及加载方式等。由于受到试验设备、经费等方面的限制,很难精确地研究各个影响因素而反复进行试验,因此对剪力墙抗侧性能的深入研究受到一定的限制。采用有限元方法,只要其有效性得到验证,就可以大大节约时间及成本。本文采用有限元软件SAP2000及ABAQUS,以经过试验的剪力墙为例进行单向荷载下的模拟分析,并与试验结果对比,比较两种软件的模拟结果、分析精度和适应性,为今后木结构剪力墙的有限元分析提供参考。Wood shear walls are the main structures to resist lateral loads of light wood-flamed construction. Their lateral resisting performance is related to various configurations, such as nail diameter, nail spacing, sheathing arrangements, sheathing size, blocks and loading system. It is impossible to study every factors using test due to experimental equipments and high cost. If the validity of the finite element method is verified, a lot of time and cost could be saved. The simulated analysis under monotonic loading was carried out with the performance of tested shear wall as example using finite element software SAP2000 and ABAQUS. Results obtained by two kinds of software are compared with the test results and some references will be provided to the further finite element study.
