Due to Faraday’s Law of Induction and Lenz’s Law, a new application is created incorporating eddy current damping which consists of the permanent magnet and metal conductor into a large-scale, pendulum-based TMD in tall buildings to mitigate the structural vibration under wind or seismic scenarios. A shaking table test of a five-story steel frame with eddy-current TMD was performed and the results are presented to evaluate the earthquake-induced vibration control performance. The results indicate that the earthquake-induced acceleration and displacement response of the steel frame can be effectively reduced by the TMD. A 1000 ton eddy-current TMD was installed on the top of Shanghai Center Tower (SHC), a 632m-height building in China. Numerical analysis of the SHC structural model with the TMD was conducted and the results indicate that for SHC the eddy-current TMD was able to reduce wind-induced structural acceleration by 45%60% and earthquake-induced structural displacement by 5%-15%.
