Robustness study of the pounding tuned mass damper for vibration control of subsea jumpers
Smart Materials and Structures, 2015A previous study by the authors proposed a new type of damper, the pounding tuned mass damper (PTMD), which uses the impact of a tuned mass with viscoelastic materials to effectively dissipate vibration energy, for structural vibration control. However, the control performance is unknown if the PTMD is not tuned to the targeted frequency of the primary

To explore the application of traditional tuned mass dampers (TMDs) to the earthquake induced vibration control problem, a pounding tuned mass damper (PTMD) is proposed by adding a viscoelastic limitation to the traditional TMD. In the proposed PTMD, the vibration energy can be further dissipated through the impact between the attached mass and the ...

AbstractThe purpose of this paper is to present an innovative insight into the behavior and energy dissipation mechanism of a single‐degree‐of‐freedom (SDOF) structure controlled by pounding tuned mass damper (PTMD). In this study, a shake table test was conducted to investigate energy response of the SDOF structure incorporated with PTMD and subjected

Abstract The production of intelligent materials in the design of vibration control devices have made significant progress in the past two decades. Since the shape memory alloy (SMA) is a superelastic intelligent material highly capable of dissipating energy, use has been made in this research of the SMA pounding tuned mass damper (SMA-PTMD) to ...

Use of a shared tuned mass damper (STMD) to reduce vibration and pounding in adjacent structures
Earthquake Engineering & Structural Dynamics, 2001AbstractThe dynamic response of tall civil structures due to earthquakes is very important to civil engineers. Structures exposed to earthquakes experience vibrations that are detrimental to their structural components. Structural pounding is an additional problem that occurs when buildings experience earthquake excitation.

Failures of transmission tower-line systems have frequently occurred during large earthquakes. It is essential to control the excessive vibrations of transmission tower-line systems to ensure their safe operation in such events. This paper numerically investigates the effectiveness of using a novel bidirectional pounding tuned mass damper (BPTMD) to ...
