Compliant Tuned Liquid Damper for Seismic Vibration Control of Short-Period Structures
A Tuned Liquid Damper (TLD) belongs to the class of passive vibration suppression devices. In the TLD, a liquid tank, typically filled with water, is connected to the primary structure. TLDs are primarily used to suppress vibrations in tall structures by tuning the structure's fundamental period with the oscillation period of the sloshing liquid. When the lateral forces excite the liquid tank, the liquid (usually water) inside the liquid tank begins to slosh. After some cycles of liquid motion, it effectively suppresses the vibration of the structure. However, adapting these types of devices for short-period structures is often not practically feasible. The present study proposes a compliant system by adopting a flexible interface between the liquid tank and the structure, to tune the liquid damper for short-period structures. The control efficiency of a compliant tuned liquid damper is assessed by subjecting the building to a set of far-field earthquake excitations. It is observed that the proposed system significantly improves the damper performance by reducing the structural responses.
