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

Figure 11

Comparison of displacement responses between controlled (dashed line) and uncontrolled (solid line) structures subject to different samples ((a) first sample, and (b) second sample) of Gaussian white noise with power spectrum strength  m·s⁻³. The frequency of the oscillator balls with a 5% mass ratio is tuned to the frequency of the main structure.
