Parametric Analysis of Damping Performance of TLD for Seismic Design of High-Rise Building

고층건물 내진설계용 TLD의 감쇠성능 파라메트릭 해석

Many researches have been studied several vibration control device such as TMD and TLD to reduce the influence of wind or seismic waves for high-rise buildings. TLD provides some advantages such as easy installation and low maintenance cost. However, because of the difficulties in evaluating the characteristics of TLD, the dynamic characteristics of TLD must be investigated by experiment or analysis. In this study, the dynamic response analysis of structure with TLD was carried out to verify the vibration control ability of the proposed TLD for high-rise building. The parameter of interest was chosen by the height of the water level and the frequency of input seismic wave in the same shape of water tank.
