Fuzzy Reliability Evaluation of RC Rigid-Frame Arch Bridge in Service

Abstract:

According to the basic principles and methods of the fuzzy reliability assessment to the existing bridge, RC rigid-frame arch bridge with Fuzzy reliability evaluation of a judgment factor sets of class I and class Ⅱare identified in this paper, aiming at the existing disease in this kind of bridge. Then, the fuzzy reliability comprehensive evaluation model of RC rigid-frame arch bridge is established. Meantime, the paper raises the membership function of each evaluation index; uses Analytic hierarchy process (AHP) to determine the weight vector of each factor. At last, a reliable practical analytical method for the evaluation of the existing RC rigid-frame arch bridge’s bearing capacity is obtained.
