摘要
本文在分析现有计算方法的基础上,提出了适合于多种结构系统可靠性分析的五种评价衡准.在失效概率的计算过程中,考虑了多种分布形式及随机变量间、失效形式间的相关性,从而为结构系统的最优可靠性设计提供了可靠的设计依据。
Based on the analysis for existing calculating methods,five evaluation criterions suiting to the relia-bility analysis of various structural systems are presented in this paper.The type of probability distribu-tion and the relativity of random variables and failure modes are taken into account.As a result,a relia-ble design basis for optimum structural design based on reliability analysis is provided.
