Abstract

Recently, it becomes a large problem that bridge vibration induced by vehicles causes damages to not only the bridge but also a pole type steel structures, such as lighting poles, marker poles on the elevated bridge. Since such damage tends to cause more severe damage, the vibration problem should be solved. As a number of such poles is large enough, it is important to improve damping performance of the steel pole with cheap cast. Then the authors suggested a vibration controlling technique for a steel pole by using wire ropes. It was found through the vibration experiment that the technique functions effectively and the vibrations of the pole can be reduced.
