Application of the Analytic Hierarchy Process in Performance Evaluation of Existing Concrete Cable-Stayed Bridge

The performance assessment of existing concrete cable-stayed bridge is discussed in this paper. These assessment indexes are classified into qualitative indexes, quantitative indexes and measurable group indexes. Analytic hierarchy process method is adopted to evaluate the qualitative indexes. Based on the experts' investigation, the judgment matrix of multiple comparisons is carried out, and the weight of single element is figured out and judgment consistency is checked, then group decision method is employed to calculate the judgment results of all experts. The corresponding assessment software is complied on the net framework 2.0 aided by the powerful development tool of visual studio 2005 C#. One certain concrete cable-stayed bridge with single pylon is inspected and assessed by the proposed method in this paper. The result suggests that the proposed method can be applied in the real bridge performance assessment.
