摘 要: 为了简化建筑结构体系可靠度的计算,有必要研究失效模式之间的相关性,它对体系可靠度的分析有重要影响.把各层的层间位移作为随机变量,以层间变形破坏为主要失效模式,采用蒙特卡罗(Monte-Carlo)方法,对多层框架结构在小震、中震和大震作用下进行了失效模式相关性研究,得出了多层框架结构在小震、中震和大震作用下部分失效模式的相关性统计规律. In order to simplify the calculation of reliability of structural system, it is necessary to study the dependency of failure modes. The dependency of failure modes has an important effect on the analysis of reliability of system. The interformational displacements are considered as random variables. The damaged interformational deformations are main failure modes. The method of Monte-Carlo is used to study the dependency of multi-layer frame structures based on storey drifts under minor, intermediate and strong earthquakes. Some statistical rules of dependency are obtained about multi-layer frame structures.
