“…In the PTMD system, the damper could not only reduce the vibration through particles and container wall collision, but also by the tunning effect as well. The current research shows that PTMD could significantly reduce the vibration induced by the seismic or wind 3,4,6,8 . The schematical illustration of PD is shown in Figure 1.…”

The particle damper made of steel balls has a great capability of vibration attenuation. However, its noise causes serious problems in the comfortability of structures. In this study, waste concrete aggregates and powders are utilized as particles in particle dampers, aiming to reduce the generated noise and achieve comparable performance as well as better environmental and ecological benefits.The parameters, including damper type, particle materials, earthquake waves, particle number, and tunning frequency on the damping performance, are investigated through free vibration test and shaking table tests. The results show that the damping ratio and seismic performance of this novel damper are comparable to those of the steel particle dampers. Moreover, simulation was conducted based on theoretical analysis. Finally, the generated sound is tested and proved less than the commonly adopted steel ball damper. This study can encourage the application of particle dampers by reducing noise and cost, besides, promotes the environmental benefits by extending the usage of recycled building materials.

Particle tuned mass damper has received considerable attention on mitigating structural seismic responses recently. However, soil-structure interaction effects have not been considered for the optimization design of particle tuned mass damper in the previous studies yet, which may play significant roles in particle tuned mass damper’s effectiveness. This paper investigates the seismic control performance of particle tuned mass damper for tall buildings considering SSI effects. A 40-story benchmark structure is adopted as the primary structure, and different soil conditions including soft, medium, dense soil, and the fixed-base case are considered. Based on the Cuckoo Search algorithm, an optimum design approach for the particle tuned mass damper implemented in SSI system under earthquake excitations is proposed, and the optimum parameters of particle tuned mass damper are obtained from the optimum design process. The optimum results indicate that the optimized particle tuned mass damper can effectively decrease the displacement response without the increase of peak acceleration, and the reduction rates could exceed 30% in some cases. Compared with other soil type cases, under soft soil condition, the optimum parameters of particle tuned mass damper are especially different, and the mitigation effects of the optimized particle tuned mass damper on maximum displacement weaken. Hence, it is necessary to consider the SSI effects for particle tuned mass damper’s seismic design. Furthermore, the interaction effects between the primary structure and particle tuned mass damper in SSI system are also evaluated through energy analysis. The results show that considering SSI effects, the optimized particle tuned mass damper device dissipates the overwhelming majority of the input energy, and it greatly decreases the structural energy, displaying excellent energy dissipation performance on seismic vibration control of structure.
