Abstract :This paper is focused on the implementation of various tuned dampers for mitigation of structural response for vibration control due to earthquake effect. Although there are various conventional methods for earthquake resistant building, like using ductile detailing provided by IS 13920-1993, there are certain limitation for the same as the past earthquake depict the failure of these structure. Hence, there is a need for modern techniques for earthquake resistant building which includes the dampers and base isolation techniques. The main focus is on passive dampers which are tuned mass damper, tuned liquid damper with and without baffle wall and tuned liquid column damper. A model is designed as a three storey building acting as conventional building. Four different types of damper arrangement are later provided on this model, functioning as TMD, TLD without and baffle wall and TLCD. These models are tested on a servo shake table to find out the displacement and acceleration of each for natural frequencies of conventional building and natural frequencies of individual dampers. Later the dampers with least displacement are tested for Koyna earthquake. Finally, comparing all the results obtained i.e., among TMD, TLD without and with baffle wall and TLCD model having maximum vibration control due to earthquake effect is found out.
