摘要
提出了其单元具有“安全 中介 失效”工作模式的各种系统的可靠性分析方法。这时 ,系统及其单元均具有安全、中介、失效三种工作状态。可靠性分析的结果是求出系统的安全概率PR、中介概率PM 和失效概率PF。它们联合起来构成可靠性向量 [PR,PM ,PF]。
An attempt is made to distinguish a civil engineering system with other systems from the viewpoint of their work states We regard a civil engineering system and its elements all have three work states but not two states The three states are the safety state,intermediate state,and failure state A method of reliability analysis for a civil engineering system is proposed in the paper The civil engineering system is considered with the intermediate state The result of reliability analysis is the set of the safety probability P R,the intermediate probability P M,and the failure probability P F of a system It is so?called the reliability vector[ P R, P M, P F] of the system Then the randomness and fuzzy iness of the work states of structures can be completely estimated In the study,the failure dependence between elements is considered
