| 中文摘要: |
| 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。本文采用Monte Carlo模拟法，分析了钢筋混凝土柱“强剪弱弯”设计的可靠度。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参考。 |
| 英文摘要: |
| According to the current code for seismic design, the parameters of reinforced concrete columns are considered as random variables. Failure mode of columns is assumed as series system. On this basis the reliability of strong shear weak bending design is analyzed using Monte Carlo simulation method。The probability of shear failure prior to flexural failure is obtained. It provides the basis for reasonably determining the strengthened shear strength factor. |
