Tuned Sloshing Damper in Response Control of Tall Building Structure

Abstract

The paucity of space and requirements of building infrastructure has driven us to explore for taller building systems. Also a large number of construction materials has emerged and are being used extensively in buildings. The usage of light weight high strength materials reduces the space requirement and also becomes economical. However, such structures have structurally become susceptible to the lateral loading generated due to wind or earthquake. Attempts are made to control the response of tall building systems by introducing control mechanisms in the form of active, passive or hybrid system. Usage of liquid storage tanks in tall building system in the form of a passive control device proves effective. Several works have been carried out in the past to understand the efficacy of such system, which popularly is known as tuned liquid dampers or tuned sloshing dampers (TSD). The present paper deals with the development of a numerical code to demonstrate the efficacy of such tuned sloshing damper considering fluid structure interaction effect.
