Experimental Study on Vibration Control of Steel Poles Using Chloroprene Rubber

Recently, it is pointed out that the bridge vibration caused by the traffic causes damage to a pole type steel structures such as lighting poles or marker poles on elevated bridges. Some damages induce collapse in the severe case and its collapse may cause secondary accidents. Therefore, vibration problem of the pole type steel structures should be solved as soon as possible. As the number of such steel poles which should be maintain sufficiently is very large, it is important to avoid resonance and to improve damping performance of them economically. The presented herein are discussed a proposed vibration controlling technique for steel poles by using chloroprene rubber base and the effectiveness of this method based on the experimental results. .
