Abstract: A tuned mass damper (TMD) is a passive energy dissipating device which is comprised of a mass, spring and a damper. The idea behind this type of dampers is that if a smaller mass is attached to the multiple degrees of freedom system and its parameters are tuned precisely, then the oscillation of the whole system can be reduced by this smaller mass. In this work, different dampers of different frequencies were designed and integrated with the three-storied building frame model to minimize its first mode of vibration along x-axis at a frequency of 3Hz. The best suitable damper was determined through the numerical analysis was then fabricated and tested for the validation of the result. It was found that for the TMD of 3Hz the reduction in the response of the structure was found to be around 83.72%.
