| Abstract: | Aiming at the defects in the current bridge evaluation parts of maintenance codes,for instance,the imperfect classification of components and rough calculation of weight,a hierarchical structure model of CFST arch bridge is established,and the analytic hierarchy process method based on exponential scale is used to calculate components weight.The designing load-bearing capacity and distress condition are used as indexes of safety evaluation and the index system for CFST(concrete filled steel tubular) arch br... |
