Mitigation of wind-induced response of Shanghai Center Tower by tuned mass damper

With a height of 632 m, the Shanghai Center Tower, located in Lujiazui district of Shanghai, will be the highest building in China. A tuned mass damper (TMD) system will be set in the upper part of the tower to control the structural wind-induced response. A brief description of fluctuating wind speed simulation is given first. Secondly, analysis of along-wind response of the Shanghai Center Tower was carried out in frequency domain and time domain, through which the wind-induced vibrating comfort of the Shanghai Center Tower and the TMD control performance can be evaluated. Then, the approach that a TMD is installed in the upper part of structure to control the structural wind-induced response and to increase resident comfort of super high-rise building proves to be effective through the analysis results.
