KBES for evaluating R.C. framed buildings using fuzzy sets

Abstract A methodology for developing a knowledge-based expert system for assessing the structural condition of existing reinforced concrete buildings is proposed in this paper. The procedure incorporates the results of field observations and, if necessary, strength computations of individual members and combines these using weighting factors to obtain the overall structural condition of the building. The lack of precision associated with verbal descriptions used in recording some field observations is expressed using fuzzy set notation. Elements of fuzzy set theory are also used in the reasoning process. A KBES incorporating this methodology and using expertise based primarily on the experience of a team of investigating engineers at Tongji University, China, is described.
