title = "Effectiveness of variably tuned liquid damper in suppressing dynamic excitation",
abstract = "Tuned liquid damper (TLD) is a special type of auxiliary damping device which relies on the sloshing of a liquid (water) in a container to counteract the forces acting on the structure. In this paper a new kind of TLD with some movable baffles is experimentally studied. These movable baffles change the dynamic characteristics of the TLD, specially frequency and damping. Response of a five storey benchmark building was utilized to investigate the efficiency of variably tuned liquid damper (VTLD) under dynamic excitations. By observing the performance of VTLD this study investigates the effects of probable mistuning by changing the depth of water and frequency ratio as well. The damping ratios of the building in several conditions of baffles angles were evaluated using logarithmic decrement technique. The results show that one can enhance the performance of TLDs by installing some movable baffles and overcome probable mistuning of the TLD.",
