Abstract

Here, based on a 20-story nonlinear benchmark building, vibration reduction effect of a tuned impact damper (TID) system designed optimally and its superiority over conventional designs were investigated.A reduced-order model of the original finite element (FE) one was obtained with the parametric identification algorithm.Based on the reduced-order model, the optimal design method based on performance was proposed to do optimal design for parameters of a TID system.The vibration reduction effect of the original FE model with an additional TID system optimally designed was analyzed.The study results showed that the vibration reduction rate of the TID system optimally designed can be increased by 50% compared with that of the conventional design; the number of plastic hinges decreases from 86 of an uncontrolled structure to 62, while for the conventional design, the number of plastic hinges keeps unchanged, only their distribution in stories changes; compared with the conventional design method for parameters of a TID system, the performance-based optimal design method for a TID system can not only mitigate displacements and inter-story drift angles of the main structure, but also reduce number of plastic hinges and plastic energy dissipation of a nonlinear structure, and further reduce structural damages under a large earthquake.
