摘要
为了简化结构体系可靠度的计算,有必要研究失效相关性问题。文中以层间变形失效为主要失效模式,采用Monte-Carlo方法,在中震作用下对RC高层框架结构进行了失效相关性研究。研究结果表明:钢筋混凝土高层框架结构在中震作用下,各层之间的失效既不是完全统计相关的,也不是完全统计独立的;失效相关的层间数约占总层数的1/2,失效相关的层间主要集中在结构的中下部。
In order to simplify the calculation of structural system reliability,it is necessary to study the problem of failure dependence.In this paper,the failure dependences of RC high-rise frame structures are studied by using Monte-Carlo method under moderate earthquakes based on storey drift.The study results indicates that the failures of different stories of reinforced concrete high-rise frame structures are neither absolutely independent nor absolutely dependent.The number of failure dependent stories of frame structures accounts for one-half the number of total stories under moderate earthquakes,which concentrates on the middle and lower part of structure.
