摘　　要：在建筑结构的设计与分析中,结构体系可靠度的概念和思想已日益为人们所接受,但它的计算却一直是一个难点问题.特别是在体系可靠度的计算中涉及到了失效约束或者失效模式间的相关性问题.本文以层间位移为分析对象,采用蒙特卡罗方法,对多高层剪力墙在小震下的结构反应进行了失效相关性的分析研究,得出了多高层剪力墙结构在小震作用下的部分失效相关性规律.The concept and idea of reliability of system has been accepted in the design and analysis of building structures, but its calculation is a difficult point all the while. The failure dependency of failure constraints or modes is involved during the calculation of reliability of system. In this paper, the method of Monte-Carlo was used to study the dependency of multi-layer and high-rise shear walls under the action of minor earthquakes based on inter-bedded displacements, and some rules of dependencies were obtained about multi-layer and highrise shear walls under the action of minor earthquakes.
