Seismic Response Reduction of Structures Equipped with a Voided Biaxial Slab-Based Tuned Rolling Mass Damper

<div>Comparison between interstorey drift ((a) first storey, (b) sixth storey) of structures with (solid line) and without (dashed line) TRoMaDaS. Structure subjected to scaled El Centro acceleration (peak acceleration = 1.026 m/s<sup>2</sup>). TRoMaDaS oscillators with a mass ratio of 5% are installed on the third (one ball) and fourth floors (10 balls with equal mass) of 3% and 2% of the main structure mass, respectively.</div>
