FUZZY RELIABILITY ANALYSIS BASED ON GENERALIZED FUZZY RANDOM STRENGTH

Abstract

Abstract: Determination of the membership function of fuzzy safety state is the key of fuzzy reliability analysis of structure. The fuzziness and randomness of generalized stress and generalized strength are simultaneously considered, two main characteristic factors that influence the value of fuzzy number are analyzed, the calculation theory of the membership function of fuzzy safety state is developed by using the information obtaining from fuzzy number, and structural fuzzy reliability analysis method based on defining fuzzy safety state by generalized fuzzy random strength is presented. An example is given to illustrate the method.

Key words: Fuzzy number, Fuzzy reliability, Fuzzy safety event, Generalized fuzzy random strength, Membership function, Base iron, Ductile iron, Dynamic adjustment and control, Grey correlation, Nodularization and inoculation
