| 摘 要： | 目前,基于性能的建筑结构抗震设计成为世界各国土木工程界研究的热点之一.结构体系可靠度理论是进行结构性能分析的重要的理论基础.在结构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.本文基于pushover方法,采用Monte Carlo法和随机有限元法,在小震研究成果的基础上,进一步研究了钢筋混凝土框架结构在大震情况下的失效相关性问题,分别得出了框架梁、柱在大震作用下的部分失效相关性规律.

| Abstract: | Building structure seismic design based on performance is a topic of general interest of civil engineering in the world. It should be based on the theory of structure reliability. During the calculation of reliability of structure system, failure dependency of the components or the sections is one of the key problems. In this paper, based on the pushover method, adopting the Monte Carlo and stochastic finite element method, on the basis of research results under small earthquakes, the failure dependency problem of RC frame structures was studied under strong earthquakes. Some failure dependency rules of beam and column were obtained under strong earthquakes. |
