Damping is a phenomenon in which the energy of the system is gradually reduced and finally the vibration of the system is completely eliminated and the system is brought to rest. Several technologies are available to minimize the vibration of structures, of which, use of Tuned Liquid Damper (TLD) is a recent development. TLD is traditionally made of rigid tank filled with water. Once excited, the water inside the tank experiences sloshing motion as a result of building vibration and dissipates energy through the sloshing and wave-breaking of the liquid. This paper aims to study the effectiveness of TLD in reducing seismic vibration of a two-storied building frame when it is subjected to horizontal excitations. Analytical study of the undamped frame was carried out in ANSYS WORKBENCH software. Based on modes and frequencies obtained from analytical study, dimensions of steel building frame were fixed and experimental study was carried out by shake table experiments. Also various parameters that influence the effectiveness of TLD are studied.
