ANALYSIS OF ANTI-SEISMIC PERFORMANCE OF BEIRAOYANG RIVER BRIDGE REINFORCED WITH CFRP

There is a dangerous bridge over Beiraoyang River in Fuxin city,carbon fiber reinforced polymer(CFRP) reinforcement plan is presented combining with this project case.To verify the reinforcement effect,finite element analysis of both reinforced and unreinforced triple-rib arched girder with static loading is completed.The results of stress and deformation show that CFRP can reduce deflection and increase bearing capacity of the bridge.The analysis of principal stress and displacement response of both reinforced and unreinforced bridge show that both strength and stiffness of the structure can be increased by sticking CFRP,and anti-seismic performance of the RC bridge is improved remarkably.
