楼层抗剪承载力之比的计算及调整措施探讨

Discussion on the Calculation and Adjustment of the Ratio of Floor Shear Capacity

楼层抗剪承载力之比是在结构设计工作中经常遇到的一个参考指标,可以用来判断和控制楼层竖向不规则的程度,还可以用于计算楼层屈服强度系数,计算罕遇地震作用下楼层薄弱层的弹塑性变形。工业建筑结构竖向不规则会导致此指标经常不满足规范要求。论文通过柱构件抗剪承载力的计算方法,探讨影响楼层承载力突变的因素以及相应的调整措施。

The ratio of floor shear capacity is a reference index often encountered in structural design,which can be used to judge and control the degree of vertical irregularity of the floor,also can be used to calculate the yield strength coefficient of the floor,and calculate the elastic-plastic deformation of the weak floor under rare earthquake.The vertical irregularity of industrial building structure often leads to this index not meeting the specification requirements.In this paper,through the calculation method of shear bearing capacity of column members,the factors that affect the sudden change of floor bearing capacity and the corresponding adjustment measures are discussed.
