| Abstract: | In city development of economy and structre bring traffic and carrying capacity of vehicle on increasingly. The reinforced concrete beam of the YaAn Bridge couldn’t bear actual load. In order to improve bearing capacity of the YaAn Bridge,augment the steel ratio of the reinforced concrete beam. In this paper ,the project design for repairing and strengthening of the reinforced concrete beam is introduced. |
