Abstract
Tuned liquid column damper (TLCD) is more advantageous in terms of space than TLD so that it is far more advantageous when it comes to installation on the actual building. To investigate the effectiveness of a tuned liquid column damper (TLCD) in mitigation wind-induced excitation motion of a tall building, aeroelastic experiments were conducted. A 1: 200 scaled model of an aeroelastic tall building was built, and TLCD models of mass ratio of 1.5% and 3%, respectively, were designed and tested with the aeroelastic model. As such, this study has installed TLCD with different lengths of horizontal pipes at the top most floor of realistic model. This is similar to the actual structure, centred on the interval where the vortex-induced vibration of low wind speed occurs, by conducting aeroelastic model tests in suburban areas and the vibration response in across-wind direction shall be found in order to figure out the wind vibration control effect according to various types (horizontal length, mass ratio) changes.
