Vibration Control of Wind Response of Tall Building Using TLD and MTLD

TLD와 MTLD을 이용한 고층건물의 풍응답 진동제어

Serviceability of buildings is affect by excessive acceleration experienced at the top floors in wind storms that may cause discomfort to the occupants. Tuned liquid damper(TLD) and multiple tuned liquid damper(MTLD) are passive control devices that consists of rigid tank filled with liquid to suppress the vibration of structures. This TLD and MTLD are attributable to several potential advantages - low costs; easy to install in existing structures; effective even for small-amplitude vibrations. In this paper, the behavior of TLD and MTLD are investigated analytically and wind tunnel test of high-frequency force balance.
