“…Passive linear TMDs are well understood and have been shown to be very effective and reliable in practice [3]. In the case of fixed-base structures, tuning of the natural frequency of the TMD to the pre-dominant modal frequency of the structure is desired to ensure the damper's optimum operational efficiency [4]. In reality however, inclusion of soil flexibility is expected to result in an overall decrease in stiffness and a different natural frequency of the soil-structure system in comparison to the fixed-base structure [5].…”

a b s t r a c tTuned mass dampers (TMDs) are widely used to reduce vibrations in structures. However, very little research is available on the experimental investigation of TMDs and their performance in soil-structure systems. In this paper, a series of geotechnical centrifuge tests was conducted to investigate the effects of TMDs on the response of a multiple-storey sway frame structure undergoing dynamic soil-structure interaction (SSI). Structural responses were recorded for a wide range of input motion characteristics, damper configurations and soil profiles. The practicality associated with the use of TMDs in the damping of resonant structures in light of unexpected earthquake characteristics different from design earthquakes was experimentally demonstrated. Tuning a TMD to soil-structure system properties rather than fixed-base structural properties was found to double the improvement in damping and reduce the original peak response by nearly half. The potential effectiveness of a de-tuned mass damper in light of significant SSI was also demonstrated.

“…Control designs considering nonlinearity of structures have been investigated [3,20]. A novel semi-active friction-type multiple tuned mass damper for vibration control of seismic structures has been proposed to keep all of its mass units to be activated in an earthquake with arbitrary intensity [14]. The effects of actuator dynamics and control-structure interaction for an electric motor, namely he impact of the mechanical design to actuator power consumption has been studies [25].…”

“…The foremost TMD device developed by Frahm in 1909 does not include the inherent damping and only works in a narrow frequency range around the resonant frequency . To increase the robustness and control performance of TMD devices, damping units were introduced in TMD systems, which can be supplied by magneto‐rheological dampers, particle (or impact) dampers, eddy current dampers, and friction dampers . Moreover, pendulum TMDs were proposed to enhance the control performance of traditional TMDs by employing the nonlinearity of the pendulum mass, and several applications in vibration control of civil structures have been reported in Roffel et al, Shu et al, and Sun and Jahangiri .…”

Summary This paper proposes a new passive control device, pendulum‐pounding tuned mass damper (PPTMD), to mitigate the response of lightly damped structures under various excitations. The proposed PPTMD consists of a tuned pendulum mass and a pounding boundary next to the equilibrium position of the pendulum mass. Moreover, a layer of viscoelastic materials called high energy‐dissipation rubber is attached on the pounding boundary to dissipate the vibration energy through impacts. A simplified impact force model was developed for modeling the pounding behavior of the high energy‐dissipation rubber pounding layer, and parameters in the simplified model were identified from free pounding experiments. The validation of the numerical method to simulate the dynamic behavior of the PPTMD was provided. The effectiveness of the PPTMD to control a single degree‐of‐freedom structure was numerically and experimentally studied under free vibration and forced vibration. The effects of the frequency tuning ratio, the coefficient of restitution, the excitation force amplitude, and the mass ratio were studied, respectively. Finally, the control performance of the PPTMD was compared with the classic tuned mass damper under free vibration, forced vibration, and several earthquake records. It is shown that the PPTMD can significantly increase the damping ratio of the controlled structure and effectively reduce the response of the controlled structure around the resonant frequency range. Furthermore, the PPTMD still achieves considerable control performance even if the frequency of the controlled structure varied in a wide range. Due to the different vibration control mechanism, the PPTMD outperforms the classic resonant frequency range in controlling the structural displacement response.
