Abstract: Fukuoka Tower, which was built in 1989, was projected as a monument, a observation tower and a broadcasting antenna with 234m high. In this tower, a Tuned Mass Damper(TMD) was set, in order to reduce the wind induced vibration. The TMD has approximately 1.5% mass of effective mass of the lower. In this paper, the structural design of the tower and the TMD is described. And the wind and wind induced vibrations on full scale measurement are discussed. As the result, standard deviations of response acceleration with the TMD was reduced to approximately 55% of the values without the TMD.
