    Abstract

    In this study, the oscillation behavior and the seismic reinforcement effect of an existing bridge with high pier are investigated by dynamic analysis method. The bridge pier is retrofitted by ground anchor and damper. The PC cables and the dampers are assumed to be strung between the column of the pier and the ground anchors. Focusing on whether to introduce an initial tension and a damper, the analysis is conducted and, the analysis results show that this reinforcement method has a significant positive effect in improving the aseismicity of the bridges with high piers.
