摘　　要：本文建议用条件概率来考虑工程系统中各结构失效的相关性。为此,提出了条件关联系数的概念和影响条件概率的各种因素,并以抗震工程系统为例给出了具体的估算方法。从而得出了计算失效相关工程系统可靠度的方法。This paper uses the concept of conditional probability to consider the structural failure dependence in an engineering system. To realize this idea, the conditional dependence coefficient is defined and the various factors which influence the conditional probability are evaluated. As an example, the estimation procedure for the conditional dependence coefficient is given in the case of aseismic engineering systems. This provides an evidence that the reliability of the failure-dependent engineering systems can be calculated with present procedure rationally.
