Comparative Study of Multi-Storey Building with or Without Using Active Tuned Mass Dampers

Abstract

In recent decades, urban development has led to the construction of increasingly taller and more flexible multi-storey buildings. With increasing height, buildings become more susceptible to dynamic forces such as earthquakes, wind gusts, and human-induced vibrations, which may cause excessive lateral displacement, discomfort to occupants, and structural damage. To mitigate these dynamic effects, vibration control devices are widely used. Among these, Active Tuned Mass Dampers (ATMD) are advanced systems capable of adjusting their parameters in real time through sensors, controllers, and actuators, unlike passive systems that remain fixed. ATMDs significantly enhance the seismic and wind performance of tall buildings by reducing their dynamic response. This research focuses on the comparative dynamic behavior of a G+25 multi-storey building with and without ATMD positioned at different levels of the structure.
