| 摘 要： | 提出了一种新的可靠性分析模型，即基于附加转角法将结构失效方式转化为随机线性互补规划模型统一处理．它不需进行结构重分析与验算塑性铰转动能力，而通过解一系列随机线性互补规划识别结构主要失效模式．算例表明本文方法是可行的，而且塑性铰转动能力不容忽视．

Reliability analysis of reinforced concrete frames |

| Abstract: | A reliability model is proposed on the basis of the Imposed Rotation Method (IRM) for both the rotation failure and mechanism collapse. The dominant failure modes are generated by solving a sequence of Stochastically Linear Complementary Programming (SLCP). The structural system reliability is assessed with rotation failure modes and collapse mechanism. The proposed method is illustrated with one example. It is found that the sectional rotation failure mode should not be neglected in the RC frames reliability analysis. |
