摘　　要：为了研究中国钉应用在木剪力墙建造中的可行性,进行了面板钉连接节点试验和剪力墙有限元分析;对采用中国钉的面板钉连接节点进行加载方向垂直于木纹和加载方向平行于木纹的试验,将得到的试验结果以节点荷载-位移曲线的形式输入到有限元分析软件中,计算木剪力墙的抗侧承载力,并与进口钉剪力墙模型的计算结果进行对比。研究结果表明:采用中国钉和进口钉的木剪力墙有着相近的抗侧承载力和刚度;有限元计算所得的木剪力墙抗侧承载力相对于《木结构设计规范》(GB 50005—2003)中的公式有足够的可靠度,因此,在木剪力墙的建造中,中国钉和进口钉可以相互替代使用。To research the feasibility of applying domestic nails in the construction of wood shear walls,authors first introduced the sheathing nail connection experiment and finite element analysis of shear wall.Then,the sheathing nail connection experiment with load direction which was perpendicular and paralled to grain was carried out respectively for applying domestic nails,and the load-displacement curves of nail connections were used in finite element analysis software to calculate lateral bearing capacity of wood shear walls,and compared with the calculated results of shear wall models for imported nails.The study results show that the lateral bearing capacity and rigidity of wood shear walls with domestic or imported nails are similar,and its lateral bearing capacity which is calculated by finite element has enough reliability compared with Chinese Code for Design of Timber Structures（GB 50005—2003）,so in the construction of wood shear walls,domestic and imported nails can be used interchangeably.
