摘要

楼层剪重比不小于最小剪重比λmin是结构设计规范中的强制性条文,在设防烈度6度、7度地区,经常出现结构楼层剪重比小于最小剪重比λmin的情况而需要调整剪重比使其满足规范要求。论文分析了规范规定最小剪重比的必要性,评述了在实际结构设计中采用的调整剪重比的方法,指出调整剪重比应结合结构层间位移角综合考虑,以便在保证结构抗震安全的基础上取得较好的结构经济性。
That the story shear-weight ratio is not less than the minimum shear-weight ratio is compulsory clause of structural design code. In 6 or 7 seismic intensity zones, it often appears that the story shear-weight ratio is not less than the minimum shear-weight ratio. So,the story shear-weight ratio needs to be adjusted to meet the structural design code requirements. The necessity of specified minimum shear-weight ratio and used adjustment methods of shear-weight ratio in practical structural design were analyzed. In order to achieve better structural economy on the basis of seismic safety, the paper pointed out that the adjustment of shear-weight ratio should be combined with the inter-story drift ratio.
