Response Behaviour of a Three Storied Framed Structure with Tuned Liquid Damper

Abstract

Tuned liquid damper is a passive damper used to control the structural vibration in structures. It is properly designed, partially filled with liquid (mostly water) is either a rigid rectangular or a cylindrical tank which is rigidly connected to the top of structure and is used as a vibration absorber. The container may be a large tank or a combination of many small tanks. Their main function is to absorb portion of the input energy associated with external dynamic excitation acting on the structure. In this paper, a water tank is been designed which acts as tuned liquid damper. This tank is been placed at the top of a three storied framed model. The model is been experimented with tuned liquid damper and without tuned liquid damper on shake table set-up along with accelerometers connected to it. The experiment is conducted with the help of sine vibration control software. The following readings are obtained in the entire three axes. Considering the displacements in all the three directions graph has been plotted. Further, a comparison is been carried out of displacements of framed model with and without water tank at the top floor.
