In case of an earthquake, an electric-railway pole that supports overhead contact lines oscillates. Especially, when natural frequency of a viaduct and that of a pole coincide with each other, resonance occurs, and there is a possibility that a pole collapses. A damping device for electric-railway pole has been invented in order to reduce the vibration caused by an earthquake or passing train. The authors conducted theoretical analyses of pole response equipped with the damping device and vibration test of real scale pole. The damping device is a sandwich structure consisting of a steel plate and a visco-elastic body, which has damping effect even for minute displacement. The result of theoretical analyses has been found to be almost identical to the result of vibration test. Moreover, as the result of vibration test, damping effect of the device has been verified.
