| 摘 要： | 由对脆性材料组成的结构，应用马尔可夫链分析了系统在时变载荷作用下的时变可靠性问题。通过对比分析说明脆性结构在时变载荷作用下的可靠性与载荷的路径有密切的关系，忽略这些关系引起较大误差。最后以一四杆脆性结构受两个时变载荷的作用为例分析了该系统的时变可靠性。

| Abstract: | Based on the Markov chain, this paper investigates the time variant system reliability of brittle structure under multiple time varying loads. Through the contrast of analyses, it is concluded that the load paths become important and need to be considered for the brittle structural system reliability. The four bar brittle structure under two time varying loads is used for numerical examples to evaluated the time variant system reliability. |
