A Tuned Mass Damper with Nonlinear Magnetic Force for Vibration Suppression with Wide Frequency Range of Offshore Platform under Earthquake Loads

<div>Experimental results for the evaluation parameters under two earthquake conditions. Evaluation indices of acceleration results under the (a) El-Centro NS seismic wave with various frequencies, (b) Taft EW seismic wave with various frequencies; evaluation indices of displacement results under the (c) El-Centro NS seismic wave with various frequencies. (d) Taft EW seismic wave with various frequencies.</div>
