摘要
Chiba Port Tower is 125 m high with a rhombus-shaped plan. On the top of the tower, a 'Tuned Mass Damper' (TMD, hereafter) was installed in order to reduce the vibration caused by strong winds and earthquakes. A lot of data during strong winds has been recorded since August 1987. From this data, it was found that the TMD works effectively when the response of the tower exceeds 0.5 cm/sec2 and that the TMD can reduce the wind-induced response of the tower by nearly 50 percent for all wind directions.
