| 摘 要： | 把构件的设计参数看作随机变量,采用Monte Carlo模拟法,分析了钢筋混凝土柱在不同荷载比下的“强剪弱弯”设计可靠度.柱构件的破坏过程看作由压弯与剪切失效模式组成的串联体系,根据剪切破坏和压弯破坏的不同后果,通过结构构件基于失效损失期望的优化模型,对现行抗震设计规范中钢筋混凝土柱的剪力增大系数进行了优化和评价.

| Abstract: | Considered the design parameters of column member as random variables,in this paper,the reliability indexes of strong shear-weak moment in the seismic design of RC column under deferent ratios between gravity load and earthquake load are analyzed,by Monte Carlo simulation method.The failure process of column member is regarded as a serial system composed of compression bending failure mode and shearing failure mode.According to the deferent severities and losses of former two failure modes,the shear enlarge... |
