钢筋混凝土结构中剪力墙的层间侧移刚度

STORY SIDESWAY STIFFNESS OF SHEAR WALL IN REINFORCED CONCRETE STRUCTURES

在钢筋混凝土剪力墙结构及框架-剪力墙结构中,剪力墙的层间侧移刚度比较复杂,与结构层高、各层墙的弯曲刚度以及剪力墙所受水平作用力的分布形式等有关。主要特点是结构底层的层间侧移刚度大,往上则逐层减小。在设计中,应按具体结构及所受的水平作用力而具体分析。

In the reinforced concrete shear wall structure and frame-shear wall structure , the story sidesway stiffness of shear wall is complex, it is relative to story height of structure and flexure rigidity of shear wall, and also to disribution type of horizontal forces acting on the shear wall .The main feature is that the sidesway stiffness of first story is the greatest, and along the height of structure the sidesway stiffnesses are reduced story by story. In design practice, concrete analysis must be conducted according to the concrete structure and horizontal forces.
