摘要：

研究了用区间变量描述不确定参数时，结构安全系数和非概率可靠性度量及其相互关系．讨论了中心、非概率及区间三种安全系数的关系．对可靠性指标、集合可靠度两种非概率可靠性度量进行了对比分析．最后建立了安全系数和非概率可靠性度量的函数关系．研究结果拓展了结构非概率设计理论．

关键词: 安全系数, 非概率可靠性, 可靠性指标, 集合可靠度, 区间变量

Abstract:

The safety factors, the non-probabilistic reliability measures and their interrelations are investigated, when interval variables are utilized to describe the uncertain parameters of structures. First, three kinds of safety factors named central, non-probabilistic and interval factors are discussed. Then a comparison between two kinds of non-probabilistic reliability measures, which are reliability index and set-theoretic reliability measure, is made. Finally, the functions of the safety factors and the non-probabilistic reliability measures are established. The results extend the non-probabilistic design theory of structures.

Key words: safety factor, non-probabilistic reliability, reliability index, set-theoretic reliability measure, interval variables
