摘要
结构系统的可靠度不仅与其影响因素的随机不确定性有关,而且与安全准则的模糊不确定性有关。考虑到以上两种不确定性的影响,对结构可靠度概念内涵进行了深入地剖析。并导出了相应的计算公式,同时给出了算例。
The reliability of structural system is not only related to its affective factors' probability, but also to its safe criteria' fuzziness. Considering the effect of these two kinds of uncertainties, this paper discusses the connotation of the concpet of structural reliability. The formulae of the present theory are derived and examples are also provided.
