剪力墙是轻型木结构中最重要的抵抗地震水平分力与风压等侧向作用的竖向抗侧力体系,其所承受的侧向力通过连接件和构件间的摩擦传递到基础上,因此剪力墙与基础间的摩擦关系直接影响到木结构建筑的设计计算、施工方式与结构可靠性。文中就木结构剪力墙(加拿大产SPF商品材制地梁)与基础面板(针叶材胶合板)间在侧向力作用下的摩擦状态进行了实体模型研究,发现两者间的摩擦因数在0.2～0.35范围内变动,讨论了产生这种结果的可能原因。此研究对轻型木结构设计与施工具有积极的指导意义。
Shear wall is a vertical anti-side force system that is most important in light wood structure to resist the horizontal force of seismic horizontal force and wind pressure, and the lateral force to be borne is transmitted to the foundation through the friction between the connecting member and the member Therefore, the friction between the shear wall and the foundation directly affects the design calculation, construction method and structural reliability of the wood structure. In this paper, a solid model study was conducted on the frictional state of wooden shear walls (Canadian SPF timber beams) and the base panel (softwood plywood) under lateral force. The friction coefficient between the two 0.2 ~ 0.35 range changes, discussed the possible causes of this result. This study has a positive guiding significance for the design and construction of light wood structure.
