An evaluation method of bending stiffness of existing simply supported RC bridge beams is suggested.Reinforcement bond factor is adopted to reflect the influence of durability deterioration on the bending stiffness of RC bridge beams.Three plate type RC beams that had been in service in a bridge for 33 years and had various degrees of durability deterioration were tested.The evaluation results are in good agreement with the test results.Thus the basis is provided for the relevant bridge supervision department to perform applicability appraisal on the simply supported RC bridge beams.
