摘要

通过分析框-剪结构的协同工作原理,从概念上探讨了剪力墙局部中断的合理性。结合2个工程实例,对剪力墙局部中断与均通至顶部两种情况的周期、位移、刚度比、配筋等方面进行比较,结果表明剪力墙局部中断对结构侧向刚度的影响可以忽略、顶部位移有所减小,抗震性能反而略优。采用此方法,可以减少混凝土用量,节约工程造价,可供类似工程参考。
Based on the analysis of interaction in frame-shear wall structures,the reasonabability of partial interruption of shear walls was discussed on design concepts.The comparison analysis of period,displacement,stiffness ratio and reinforcement on different conditions with partial shear wall interruption and all shear walls up to roof was performed based on two practical engineering projects.The results show that the influence of partial shear wall interruption on lateral stiffness of the structure can be neglected,roof displacement can be reduced slightly and the seismic performance is enhanced slightly.Volume of concrete can be reduced and the project cost can be cut accordingly by using this method.
