摘要：基于现行建筑抗震设计规范（GBJ11-89），把钢筋混凝土柱的设计参数看作随机变量，柱的破坏看作由抗弯与抗剪失效模式组成的串联体系，采用Monte Carlo模拟法，分析了钢筋混凝土柱“强剪弱弯”设计的可靠性。重点分析了不同轴压比下，钢筋混凝土框架柱剪切破坏先于弯曲破坏发生的概率，为合理的确定剪切增强系数提供分析参考。

Abstract: Based on current seismic design code, design parameters of reinforced concrete columns are considered as random variables. Failure mode of columns is considered as series system. Reliability of Strong shear-weak bending design is analyzed by Monte Carlo simulation method. The probability of shear failure prior to flexural failure is obtained, Aiming to provided to reference for determining shear strength factor. 
Keywords: reinforced concrete column Strong shear-Weak bending reliability analysis Monte Carlo simulation
