000021915 520__ $$2eng$$aA newly developed eddy-current tuned mass damper (TMD) was used for the vibration control of Shanghai Center Tower, which is a superhigh-rise landmark building in China with a height of 632 m. In order to mitigate its vibration during wind storms, a new eddy-current TMD was installed at the 125th floor. Special protective mechanisms were incorporated to prevent excessively large amplitude motion of the TMD under extreme wind or earthquake scenarios. Results of reduced-scale laboratory tests and field tests are presented in this paper to characterize the dynamic properties of the damping device and validate the fidelity of the numerical results. Results of structural analyses for the tower indicate that the eddy-current TMD was able to reduce wind-induced structural acceleration by 45%–60% and earthquake-induced structural displacement by 5%–15%. The installation of the TMD was completed in December 2014 and the site measurements were conducted in July 2015 during the wind season of Shanghai. The response observed to date validates that the vibration control system performed quite well and the dynamic behavior of the system is very stable.
