Evaluation of a pendulum pounding tuned mass damper for seismic control of structures
Engineering Structures, 2021Abstract The pendulum pounding tuned mass damper (PPTMD) is an effective passive control device for structures under harmonic excitations. The primary objective of this study is to evaluate the performance of PPTMD for vibration control of SDOF and MDOF structures subjected to ground motions.

Pounding tuned mass dampers (PTMD), which relies on impact to dissipate vibration energy, have shown remarkable performance in suppressing structural vibrations with its modest design. However, the optimum design of PTMDs is computationally expensive due to non-smooth contact-impact behavior. This study provides a computationally efficient approach to

Parametric study of pounding tuned mass damper for subsea jumpers
Smart Materials and Structures, 2015In previous study, a pounding tuned mass damper (PTMD) was proposed to reduce the undesired vibration of a subsea jumper. Both experimental and numerical results verified the effectiveness of the PTMD. This paper aims to enhance the understanding of the PTMD through a parametric study.

Vibration Control of a Pipeline Structure Using Pounding Tuned Mass Damper
Journal of Engineering Mechanics, 2016AbstractPipeline structures are often very flexible and susceptible to vibrations induced by many sources, such as vortex, external flow, and internal fluid flow. The pounding tuned mass damper (PTMD) is one device that may be employed to absorb and dissipate these undesired vibrations.

Numerical modeling and experimental study on a novel pounding tuned mass damper
Journal of Vibration and Control, 2017Owing to its easy implementation and robustness, the pounding tuned mass damper (PTMD), which uses viscoelastic materials to cover the pounding boundary to increase the energy dissipation during impact, has been studied in recent years. The conventional PTMD design includes a gap between the pounding mass and the viscoelastic material; the value of ...

Practice Periodical on Structural Design and Construction, 2023
Pounding between adjacent buildings subjected to ground motion excitation is one of the most dangerous phenomena for building safety. In this paper, three novel configurations are proposed (two of them are uncoupled, and one of them is coupled), and two different passive devices are used, namely, tuned mass damper inerter (TMDI) and tuned inerter ...

Optimum design of a novel pounding tuned mass damper under harmonic excitation
Smart Materials and Structures, 2017In this paper, a novel pounding tuned mass damper (PTMD) utilizing pounding damping is proposed to reduce structural vibration by increasing the damping ratio of a lightly damped structure. The pounding boundary covered by viscoelastic material is fixed right next to the tuned mass when the spring–mass system is in the equilibrium position. The dynamic
