| 摘 要： | 根据《建筑抗震设计规范》（ＧＢＪ１１－８９）要求，对７～９度时的钢筋混凝土框架结构在进行罕遇地震作用下的薄弱层弹塑性变形验算时，需要确定楼层受剪承载力，但按照常用的计算方法计算时，工作量大，且较繁琐。笔者对常用的“拟弱柱化法”的计算公式进行简化，提出了实用计算公式，使计算更简单，工作量大大减少，而且误差很小，方便了设计使用。

| Abstract: | Accordingto “BuildingcodeforSeismicDesign”(GBJ11 89),in the calculation of elasticplastic deformation of some weak storey in a R C frame under exceptional seismic load (during an earthquake with damaging capacity of 7～9), it is necessary to determine the shear resisting capacity of such storeys If the conventional methods were used in this case, a large amount of tedious calculation would be involved Therefore in this paper, the formulas in the simulated weak columns method are simplified and corresponding practical formulas are given The simplified method can considerably reduce the calculation work with little loss of precision hence can be conveniently used in design |

| Keywords: | shear resisting capacity of storeys bending capacity reinforcement details characteristic values of materials |
