【摘要】 本文提出了不同于文献［１］的关于考虑结构抗力模糊性与随机性的结构可靠度实用计算模型，给出了其图形解释及应用算例，并对单纯考虑抗力的模糊性或随机性以及考虑抗力的模糊随机性对结构可靠度的影响大小作了初步分析。结果表明：对其模糊性应引起足够的重视。在抗力同时存在模糊性和随机性时，对结构可靠度应综合评定。更多还原

【Abstract】 In this paper,the practical calculating model of structural reliability considerring both fuzzy porpety and rrandom effect of structural resistence is proposed. It is different from reference[1]. And presented its graph explanation,and an example is given for practical purpose. This paper describes the effect of the fuzziness of the randomness and both properties on the reliaility. This results show that the fuzziness con not be neglected. When the fuzzy property and random effect exist simultaneously,it must be comprehensive assessed.更多还原
