摘　　要：为了简化结构体系可靠度的计算,本文采用蒙特卡罗法,对RC整体剪力墙在小震作用下进行了失效模式相关性研究．研究结果表明:不同层之间的失效既不完全独立也不完全相关,而是介于两者之间．下部楼层(约占总层数的1/2)各层的失效是独立的,上部楼层(约占总层数的1/2)各层的失效是相关的．In order to simplify the calculation of structural system reliability, the dependence of RC Non-coupied shear walls were studied by using Monte-Carlo method under minor earthquakes in this article. The study results indicats that the failures of different storeys of RC holistic shear walls are neither absolutely independent nor absolutely dependent. The failures of the lower storeys （approximately accounting for half of the total storeys） are independent. The failures of the top storeys （approximately accounting for half of the total storeys） are dependent.
