RESEARCH ON BRIDGE STATE EVALUATION BASED ON ANFIS
An evaluation index system for durability capacity of existing reinforced concrete short/medium span bridges was established. The grading standard of evaluation index was defined, and a durability evaluation system for main girders of existing bridges based on ANFIS was constructed. Using statistics analysis, a method to simulate the investigation of expert was brought up based on bridge inspection and experts attitude. The feasibility of this method was validated by-some instances. The results demonstrated the agreement between evaluation results from the system after training and bridge experts, the learning ability and practicality of the system is proved to be good. The nonlinear fuzzy inference process of bridge experts can be imitated fast and accurately. By establishing corresponding evaluation index system, this system can be used to evaluation not only the durability of RC girder bridges, but also the performance of PC and steel bridges.
