Abstract

Swimming pools in a skyscraper are not only an entertainment facility but also a boon of a structural design engineer to curb the impact of lateral forces such as wind, earthquake, etc. The usage of swimming pools as liquid tuned damper is a cost effective alternative without having any additional component within the structure. Much of the research to damp the vibration of the structure like base isolation, bracing, in-fills and dampers is available the literature.In this experimental study, it is intended to perform a parameter study of tuned liquid damper by changing aspect ratio**, i.e., the depth of water to the length of the container and by changing the mass ratio, i.e., mass of the tuned liquid to the total mass of the frame unit. This study revealed the aspect ratio of 0.25 has better efficiency and the increase in mass ratio provides the improved efficiency and consistency.
