【Abstract】 This paper describes the results of loading test for detecting the load-carrying capacity of continuous curved girder bridge.The load effect of girder at the stage of service was simulated with vehicle loading system to determine the unfavorable position of testing loads.Based on the computation of stress,deflection and crack width,it provided a theoretical basis for evaluating the capacity of testing girders.更多还原
