摘 要: 体系可靠度是衡量结构整体性能的一个重要指标。在体系可靠度的计算中,一个急待解决的问题是结构构件或截面间的失效相关性问题。基于静力弹塑性分析方法,对钢筋混凝土框架结构在小震和大震下进行了失效相关性研究。验证框架结构在小震下,梁约束的失效是统计独立的结论。在小震研究成果的基础上,对钢筋混凝土框架结构在大震情况下的失效相关性问题进行进一步研究,得出框架梁、柱在大震作用下的部分失效相关性规律。 Reliability of system is an important index that evaluates holistic performance of structures. During the calculation of reliability of system, failure dependency of the components or the sections is one of the key problems that need solutions. Based on the method of static elastoplasticity, the failure dependency problem of RC frame structures studied under small and strong earthquakes. The conclusion validated that failure of beam constraints statistically independent under small earthquakes. On the basis of research achievements under small earthquakes, some failure dependency rules of beam and cohmn are obtained under strong earthquakes.
