Institute of Solid Mechanics, Beihang University, Beijing 100191, P.R.China

摘要

摘要: 相对概率可靠性模型和模糊可靠性模型，基于区间分析的结构非概率可靠性模型对数据的要求低，因此在实际工程中对非概率可靠性模型的研究越来越重要．近年来，非概率可靠性理论得到了很好的发展和完善．该文综述了已有的4种主要的非概率可靠性模型，针对线性结构功能函数，分别从度量原理、可靠性指标物理意义、适用范围和结果精度等方面对各可靠性模型进行比较与总结；针对非线性结构功能函数，对各可靠性模型的适用性进行了初步的讨论，从而对非概率可靠性模型有更加全面和深刻的理解，为实际工程中非概率可靠性模型的选取提供重要的理论依据．

Abstract: Non-probabilistic models for structural reliability, which are based on interval analysis, are much less demanding in data when compared with probabilistic reliability models and fuzzy reliability models. Therefore, study of non-probabilistic models for structural reliability becomes more and more significant in practical projects. Theory of non-probabilistic models for structural reliability was well developed and improved in recent years. The existing four main non-probabilistic models for structural reliability were reviewed. With regard to the linear performance function, comparison and summary were made in aspects of measurement principle, physical significance of indicators, scope of application and result accuracy. As for the nonlinear performance function, the four models’ feasibility was discussed. Hence, a more comprehensive and thorough understanding of non-probabilistic models for structural reliability is achieved a theoretical base for choice of non-probabilistic models in practical projects provided.
