摘要
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。
In light wooden frame constructions,the shear wall is the most important vertical lateral resistant system which resists lateral effect as horizontal component of earthquake forces and wind pressure.The lateral force borne by this shear wall is transmitted to foundation by both nailed and other mechanical joints and friction.So the friction relationship between shear wall and foundation directly affects the design calculations of the wooden architecture,construction methods and structural safety performance.In this paper,static cyclic tests are conducted to estimate the effect of frictional force on the lateral force at this boundary.The observed apparent frictional coefficient between SPF bottom plates and softwood plywood sheathing panels varies in a wide range from 0.2 to 0.35.It discusses the possible reasons for this outcome.This study has a positive significance for the design and construction of a light wooden structure.
