The objective of this paper is to demonstrate the design and implementation of an Active Tuned Mass Damper (ATMD) and to determine its effectiveness experimentally and theoretically. ATMDs are damping units placed in structures where a mass is actuated to move out of phase with respect to the movement of the structure to reduce vibrations.

In this chapter Tuned-Mass-Dampers (TMDs) are explained. At the beginning the mechanical characteristics and their operation are discussed, and then the design criteria for these seismic isolation systems are defined. At the end of the chapter two practical examples of TMD and Active-Tuned-Mass-Dampers (ATMDs) are inserted.

Vibration Control Using Multiple Tuned Mass Dampers
Journal of Sound and Vibration, 1994Summary: This paper examines multiple tuned mass dampers (TMD's) with natural frequencies distributed over a frequency range. An integral form for the impedance is developed by asymptotic techniques. The result is used to analyze the vibration control capabilities of multiple TMD's for structures subjected to wide-band input.

Nonlinear Rooftop Tuned Mass Damper Frame
2012Innovative strategies driven toward improving the structural and nonstructural performance of existing buildings during large earthquakes are of paramount interest for researchers and practitioners of earthquake engineering. Likewise, strategies for enhancing performance of new structures in cost effective ways is a key issue for designers and owners ...

Recent seismic events have highlighted the vulnerability of reinforced concrete buildings, especially soft-story structures, to damage and collapse during strong earthquakes due to the ground's vibrational response. This study aims to mitigate these adverse vibrations using passive control mechanisms, particularly tuned mass dampers (TMDs ...

Seismic Effectiveness of Tuned Mass Dampers
Journal of the Structural Division, 1981Time history analysis of 1DOF systems with and without a tuned mass damper, subjected to a set of historical earthquakes, shows that the peak response ratio (ratio between the peak responses with and without damper) depends primarily on damping constants and on earthquake duration.

This chapter is concerned by tuned-mass damping systems. We start with an introductory example of a tuned-mass damper (TMD) design and a brief description of some of the implementations of TMDs in building structures. A rigorous theory of TMDs for single-degree-of-freedom (SDOF) systems subjected to harmonic force excitation and harmonic ground motion ...

This study proposes integrating the particle damping technology into multiple tuned mass damper (MTMD) to form a multiple tuned impact damper (MTID) system for suppressing the vibrations of nonlinear high-rise buildings under earthquakes. A systematic performance comparison comprising vibration damping effects and working strokes between the optimal ...
