Study on Vibration Reduction Control of Distributed Multi⁃tuned Impact Dampers
To improve the multi-mode control performance of particle dampers for high-rise structures, a type of multiple tuned impact damper (MTID) is proposed by combining particle damper with multiple tuned mass damper (MTMD). The superiority of the multi-objective optimal MTID over the single tuned mass damper (STID)is verified, and the performance of various distributed MTID systems is investigated. The results show that the optimal MTID performs better in reducing dynamic responses, nonlinear deformation and plastic damage of the structure as compared to STID. It is very effective to determine the location of TIDs in MTID system based on the modal characteristics of the structure, and the optimal vibration control performance can be obtained when each TID is attached to the floor with the largest mode amplitude.
