Abstract

Abstract

In order to improve the safe evaluation reliability of bridge, a fuzzy reliability evaluation model of defective RC beam bridge was put forward by fuzzy evaluation theory, analytical hierarchy process method and probability method. Through establishing fuzzy evaluation criterion, determining item level factors, index level factors and their weight coefficients, constructing probabilistic matrix of membership degree, the score of fuzzy reliability evaluation of defective RC beam bridge was calculated by weighted average method. The score was switched to fuzzy reliability index by the bounds of target reliability index and lowest reliability index. An existing multi-span RC beam bridge with 25 years was evaluated by the method. Its fuzzy reliability index is 3.769, which accords with the bridge condition. The evaluation result indicates that the method is feasible.
