Abstract
Full-scale measurements of the wind-induced responses of four buildings (two airport towers, an observatory tower and a highrise hotel) were conducted to prove the efficiency of tuned liquid dampers (TLDs). The damping ratios of the buildings with and without TLD were evaluated by both the run-down test technique and the random decrement technique. The wind-induced responses of the buildings were measured before and after installation of TLDs. The exceedance frequency of the response over the human perception thresholds was also examined. The results obtained in this study demonstrate that the TLDs could significantly improve the serviceability of the buildings.
