A review of representative research on tuned massed dampers (TMD) reported in journals in recent years is presented. TMDs are divided into four categories: conventional TMDs, pendulum TMDs (PTMDs), bi-directional TMDs (BTMDs), and tuned liquid column dampers (TLCDs).

Smart Materials and Structures, 1992
A new control strategy to improve a tuned mass damper (TMD) is developed for the vibration control of a large structure subjected to external disturbances. The feedback gain of the proposed algorithm is linear to the response acceleration of the primal system and it is optimized in the frequency domain under a harmonic excitation.

Series-Type Pendulum Tuned Mass Damper-Tuned Sloshing Damper
Journal of Vibration and Acoustics, 2019Abstract A pendulum-type tuned mass damper (TMD)-tuned sloshing damper (TSD) system is proposed as a cost-effective device to reduce wind-induced structural motion. Lagrange's principle is employed to develop an equivalent mechanical model for the system.

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.

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.
