Comparison between the interstorey drift ((a) first storey, (b) sixth storey) of structures with (solid line) and without (dashed line) TRoMaDaS. Structure subject to scaled Kobe acceleration (peak acceleration = 1.026 m/s2). TRoMaDaS oscillators are installed on the third (one ball) and the fourth floor (10 balls with equal mass) of 3% and 2% of the main structure mass, respectively.
