| 摘 要： | 结构模糊可大度分析是同时考虑结构变全的随机性和模糊性评估结构可靠度的方法。目前已提出的方法需进行高维积分，当随机变量的数目较多时计算量较大，难以直接应用。根据不同的精度要求，本文提出结构模糊可靠度分析的一次二阶矩和四阶矩方法，为模糊可靠度方法的实际应用开辟了新的途径。

| Abstract: | Structural fuzzy reliability an alysis is to calculate the reliability of structureconsidering random and fuzzy of structural variables simultaneously.The method used needs multi-dimensional integration,the qtiantity of calculating is too large when there are more random vari-bles,so that not easy to use in practice. This paper presents the firstorder second -moment method andfour-moment method for structural fuzzy reliability analysis and provides favourable factors for ap-plication of fuzzy reliability methed. |
