概要
- 論文の詳細を見る
This paper deals with a new countermeasure against wind-induced cable vibrations called "changing vibration modes method", in which growth of the unstable fundamental vibration mode is suppressed by dissipating vibration energy in higher mode generated by a permanent magnet installed near the lower end of the cable. In this paper, first, a parameter design method for "changing vibration modes method" is proposed and we showed its effectiveness by simulation results. Second, the proof that this countermeasure was effective against rain-wind induced vibration is demonstrated by trial application to an actual bridge.
