Abstract

Wind-induced response analysis of Hefei TV Tower of 339m high is performed and the serviceability design criterion of human comfort is discussed. It is found that the acceleration response of the upper turret of the tower is much larger than the allowable acceleration of human comfort. Therefore, the water tank of 60 tonnes on the tower which is used for daily water supply and fire protection of the tower is designed as a tuned mass damper in addition to its original functions. After extensive parametric studies in frequency domain, the optimal design parameters of tuned mass damper are determined. With the optimal tuned mass damper installed, the serviceability performance of the tower is improved significantly. Especially, the acceleration response of the upper turret is reduced by as much as 49%. A graphical approach of selecting the optimal TMD parameters is provided.
