Vibration caused by running vehicles on a highway bridge is spread to the superstructure, substructures and ground. The ground vibrates both in horizontal and vertical direction. When vehicles load at the tip of the cross beam in the T-shaped pier, rocking vibration of the pier occurs. Its ground vibration in transverse direction is the biggest. In the two-box girders bridge, which bearings are installed at the tip of the cross beam of the T-shaped pier, the ground vibration has greatly occurred due to the rocking vibration of the pier. Two measures to mitigate the vibration are proposed in this study. The evaluation the change of the vibration characteristics and effects of the measures to mitigate the vibration are also discussed in the study.
