AbstractIn view of the situation that the bearing capacity of bridges become lower with the development of economy and trafficthe specific reasons for reinforcement and reconstruction of the reinforced concrete beam bridge are analyzed. Considering the various methods and applicability and characteristics of the reinforcement and reconstruction, that the whole stress status of old and new elements, the structure improvement factor, and the cost and benefit coefficient should be calculated and analyzed. These results provide references for reinforcement and reconstruction of the reinforced concrete beam bridge.
