Optimisation Design and Damping Effect Analysis of Large Mass Ratio Tuned Mass Dampers

<div>The damping effect of different mass ratio TMDs on the displacement-time history of the main structure (<i>T</i> = 2.0 s) and the relative displacement-time history between the TMD and the structure (w.o. denotes the displacement of a structure without a TMD).
