基于Pushover方法的混凝土框架梁失效及相关性分析

An analysis of failures and failure dependencies of the RC frame structuresbased on the pushover method

采用Pushover方法,并通过大量的Monte Carlo数字模拟,对强柱弱梁钢筋混凝土框架结构梁的失效和失相关样本进行了统计分析。分别得出了框架结构梁在小震和大震下的失效及相关性规律,并验证了“在小震下框架结构截面约束的失效服从独立性假设”的正确性。

By means of the Pushover method and the Monte Carlo random analysis, it is concluded out some failure and failure dependency rules of the RC frame beams under the small and the strong earthquakes. And it is validated that the section restrictions of a RC frame under the small earthquakes obeys the failure independency hypothesis is correct.
