摘要
根据工程设计中存在的大量的模糊性因素，特模糊理论与结构可靠性理论相结合，分别建立了基本空间为连续集和离散集时结构的模糊随机可靠度公式及一些特殊可靠度公式；运用模糊集合基本运算法则，获得结构安全这一模糊随机事件的隶属度表达式；通过算例形象地阐述了计算方法，并分别给出由随机模糊性、随机性和模糊性所引起的结构可靠度值。
According to be a great deal of the Fuzzy factor in engineering design, the Fuzzy theory iscombined with the reliability theory in this paper. The expressions of the Fuzzy-random reliability of thestructure are established, respectively, when basic space is continuous set and disperse set. The membership function expressions of the Fuzzy-random event of structural safety are obtained by using the basic operative law of the Fuzzy sets. The calculative method is expounded imaginatively by using the calculativeexamples, and the reliability values caused by the Fuzzy-randomness, Fuzziness and randomness are given,respectively.
