| 摘 要： | 模糊不确定性和随机不确定性一样，对结构可靠性有影响，而现行的结构可靠度理论对此无法考虑．本文用模糊数学模式来定量确定其对结构可靠度的影响．通过对某重力坝用改进ＪＣ法程序计算该坝可靠度和考虑模糊不确定性对可靠度的影响，提出了有益于可靠度计算的建议．

| Abstract: | Just like stochastic uncertainty,fuzzy uncertainty will affect the reliability of structure.At present,the method to analyse the reliability of structure is not concerned with its influence.The aim of this paper is to present the model of fuzzy set and the quantitative analysis of influence of fuzzy uncertain factors on reliability of structure.There is an analysis example of a gravity dam in this paper.Based on the result of the analysis,a simpler method of structure reliability calculation is presented. |
