摘要
模糊性和随机性是不同的两类不确定性 ,其产生机理和物理意义均有一定差异。文中基于可能性理论 ,提出了同时含随机变量和模糊变量时结构的可靠性计算模型。该模型可给出结构模糊失效概率的可能性分布 ,可更客观、真实地反映结构的实际安全状况。实例计算说明了文中方法的应用。
Fuzziness and randomness are two different uncertainties,and often axist in one engineering problem Based on the possibility theory,a procedure for reliability calculation of the structures that contain both random variables and fuzzy variables is presented in the paper The possibility distribution of fuzzy failure probabilily of structures can be given by the proposed model Being different from some common models,the failure probability of fuzzy-random structures is taken as fuzzy variable,which may indicate the real safety state of structures objectively The computations of examples illustrate the feasibility and application of the proposed method
