(1 Department of Civil Engineering, Tianjin University, Tianjin 300072, China; 2 Tianjin Key Laboratory of Civil Engineering Structures and New Materials, Tianjin 300072, China)Abstract: An improved Analytic Hierarchy Process (AHP) method is provided to optimize strengthening method for existing structures. The weigh of different method can be calculated by the improved AHP method without adjustment of judge matrixes. Moreover, experts in group decision-making are classified by cluster analysis method. Based on one's class, each expert is given a certain weight, which can eliminate the inconsistency among the experts. With the improved method, strengthening method can be reasonably selected in a more scientific way.
Keywords: improved AHP method; group decision-making; cluster analysis; weight; existing structures
