A major part of bridge rating which is the kernel of bridge maintenance systemisusually performed based on the subjective judgment of experts in the related fields. By considering the shortage of experts in the expanding field of bridge mantenance and need for the exact diagnosis of bridge condition, the systematization of bridge rating to replace the subjective information of bridge engineers Suchas professional experience, knowledge on bridge rating, etc.has become an important problem. The present paper is to introduce a newely developed expert system capable not only of various infer-ences and judgments for maintenance but also of output of estimation results of remaininig life for existing bridges. Moreover, its application to some reinforced concrete T-beam bridges in service is also considered. For the construction of the knowledge base in cluding the subjective information related to bridge rating, a consept fuzzy set theory is adopted to deal with it. The final results produced by this system are represented by five elements of linguistic expressions with the fuzziness Value which is the degree of subjective uncertainty.
