We present a prop-type damper that can control the undesired vibration of a bridge girder. The damper consists of a prop and a damping material, and was placed between the pier and the girder of the bridge at a suitable angle. During the vertical vibration of the bridge girder, the damping material at the tip of the prop converts the vertical vibration into horizontal vibration. Owing to the horizontal motion of the damping material, the vibration of the bridge girder can be decreased effectively. We apply the prop-type damper to a three-span continuous bridge to attenuate the vibration caused by a live load. TDAP III LT (3D software for framework analyses) is used to elucidate the effects of the prop-type damper.
