Research on Fuzzy Comprehensive Evaluation of Cable-Stayed Bridges

Abstract:

As bridge span increases, people have growing concern on bridge safety and durability. The fuzzy comprehensive evaluation was introduced to assess complicated cable-stayed bridges. The calculate approach of fuzzy comprehensive evaluation was introduced first. Using the representation proposed by Professor Zadeh, the membership degree of the bridge technique status was described. The membership function of comprehensive evaluation for cable-stayed bridges was established by fuzzy statistics method. The application problem of model in the comprehensive evaluation for cable-stayed bridges was discussed, and the model was established in the composite calculation procedure of fuzzy sets. The fuzzy comprehensive evaluation theory was applied in the evaluation of the Sifangtai Cable-stayed Bridge as an example and the final results was basically consistent with that of the uncertain AHP method. It can be concluded that the theory can apply to the comprehensive evaluation of cable-stayed bridges.
