当结构由不同的抗侧力构件组成,如剪力墙、联肢墙、刚架、柱和电梯,楼梯的内筒,或是在建筑物底层将部分墙,柱截去以取得大开间,必然会产生相当大的侧向荷载重分配,在建筑物出现扭转变形时尤其如此。一般是假设侧向荷载按各构件的刚度或根据单位侧向荷载产生的顶端变位分配。此法只在过梁或楼板与墙是铰接时才会得出正确结果,即在任何平面内都不产生弯曲,显然这是不可能的。当墙起耦联作用,则在过梁和楼板中将产生弯矩。一、一种简单的分析方法假设结构由J个平行的组合体组成,组 When the structure consists of different anti-lateral force components, such as shear walls, joint walls, rigid frames, columns and elevators, the inner cylinder of the stairs, or cut off part of the walls and columns at the bottom of the building to obtain a large bay, Inevitably, there will be considerable lateral load redistribution, especially when the building is subjected to torsional deformation. It is generally assumed that the lateral load is distributed according to the stiffness of each member or the top displacement resulting from the unit’s lateral load. This method will only give correct results when the lintel or floor and the wall are articulated, ie no bending occurs in any plane. Obviously this is not possible. When the wall acts as a coupling, bending moments will occur in the lintel and the floor. A simple analysis method assumes that the structure consists of J parallel assemblies, groups
