Research on Damage Detection and Calculation for Reinforced Concrete Bridge Piers

In order to reduce the potential threat to the Guanyindian highway bridge caused by the damaged RC bridge pier, some damage detection methods including surface inspection, core-drilling test, ultrasonic-rebound test and verticality measurement are used to assess the bridge's damage condition. The finite element analysis software is employed to simulate the damaged bridge pier and to calculate its bearing capacity, thus providing technical data for the repair and future maintenance of the bridge pier. According to the results of damage detection and calculation, the verticality, the concrete strength, the bearing capacity and the crack width of the damaged No.1 bridge pier could meet the code's requirement but the damaged regions on the bridge pier need to be repaired.
