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.
