| 摘 要： | 基于性能的抗震设计是以体系可靠度理论为基础的.在体系可靠度的计算中涉及到相关性问题,它对体系可靠度的分析结果产生重要影响,需要加以考虑.文中基于层间位移,把层间位移作为随机变量,以层间变形破坏为主要失效模式,采用蒙特卡罗方法,对高层框架结构在小震作用下进行了失效模式相关性研究,得出了高层框架结构在小震作用下部分失效模式相关性统计规律.

| Abstract: | The foundation of the performance-based seismic design was the theory of reliability of system.The problem of dependency was involved during the calculation of reliability of system.It was necessary to consider the important effect of dependency on the result of reliability of system.In this paper,the method of Monte-Carlo was used to study the dependency of high-rise frame structures under minor earthquakes based on inter-bedded deformation,the inter-formational displacements as random variables and the destruction of inter-formational deformation as main failure modes.Some statistical rules of dependencies were obtained about high-rise frame structures under minor earthquakes. |
