  • The research of structural fuzzy reliability theory is to set up a model for structural fuzzy reliability analysis just considering the defining fuzzy safety state. Based on the existed theory for structural fuzzy reliability analysis, a model for structural fuzzy reliability analysis accounting interval fuzziness of random parameter was presented. Thinking about the randomness and the interval fuzziness of structural parameter, the conception and expression of fuzzy probability density function was put forward. The type and method of selecting membership function of random parameter was given. A model for structural fuzzy reliability analysis accounting both interval fuzziness of random and defining fuzzy safety state was set up. The compatibility between the model for fuzzy reliability analysis and the random reliability analysis model was discussed. A example was given to verify the validity of the method. The result of the research shows that the method for structural fuzzy reliability can more completely utilize the structural parameter information.
