Research on Evaluation for Bearing Capacity of Reinforced Concrete Bridges Based on Extension of Crack Width

GUO Hong  
With the rapid development of bridge industry in China,the evaluation for structural states of the existing bridges appears more and more important.Based on load test,this paper proposes a method to evaluate the bearing capacity of reinforced concrete bridges according to the extension of crack width,and verifies this evaluation method by means of model test for one group of reinforced concrete rectangular section beams.With the help of analysis and calculation for test data,the paper probes into the value range of safety evaluating class in the method of evaluating the bearing capacity of reinforced concrete bridges according to the extension of crack width,and verifies the feasibility of this method in practical projects.
