摘 要: 在建筑结构中,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,一个急需要解决的问题是结构构件或截面间的相关性问题.基于静力弹塑性方法,对钢筋混凝土多层框架结构在小震和大震情况下的失效相关性问题进行了研究,分别得出了框架梁、柱在小震和大震下的部分失效相关性规律. Reliability of system is an important index that scales the whole performances of building structures. During the calculation of reliability of structure system, failure dependency of the components or the sections is one of the key problems that are to be solved. In this paper, the failure dependency problem of RC frame structure is studied based on the method of static elastic-plasticity under small and strong earthquakes respectively. Some failure dependency rules of beams and columns are obtained under small and strong earthquakes respectively.
