一、概述水平荷载作用下高层建筑剪力墙结构的内力与位移,目前多采用单片剪力墙的分析方法。即根据楼板在自身平面内刚度无限大的假定,剪力墙所受到的水平力按其侧向位移刚度分配。按照这个假定,每一层楼面上所有剪力墙的水平位移相同,从而忽略了楼层在自身平面内的转动。因此,当水平力的合力作用点与剪力墙结构的刚度中心不重合时,这种分析方法不能反映剪力墙结构的真实工作情况。
1. Outline the internal forces and displacements of high-rise building shear wall structures under horizontal loads. At present, the analysis method of single-plate shear walls is often used. That is, according to the assumption that the stiffness of the slab is infinite in its own plane, the horizontal force of the shear wall is distributed according to its lateral displacement stiffness. According to this assumption, the horizontal displacement of all shear walls on each floor is the same, thus ignoring the floor’s rotation in its own plane. Therefore, when the resultant force of the horizontal force does not coincide with the center of stiffness of the shear wall structure, this method of analysis cannot reflect the real working conditions of the shear wall structure.
