Study on the loading test of the reinforced concrete bridge lack of technical data

The key points of loading test and method to accurately evaluate the bearing capacity of simple-supported reinforced concrete bridge lack of technical data are introduced in this paper. The curve of measured load transverse distribution coefficients was used to assess the transverse connections among plate girders; and the displacement ratios of all loading levels at the midspan to the first loading level were defined to evaluate the elastic behavior of plate girders under the test loads.
