摘要

本文基于一个20层非线性benchmark结构,研究了优化设计的调谐冲击阻尼器(TID)系统的减震效果以及相对于传统设计的优越性。首先采用参数识别算法得到原有限元模型的降阶模型,然后基于该降阶模型,提出了基于性能的优化设计方法对TID系统的参数进行优化设计,最后分析原有限元模型附加优化的TID系统的减震效果。研究结果表明:经过优化设计的TID系统减震率相比传统设计提高了约50%;同时塑性铰数量从无控结构的86个减少到62个,而对于传统设计,塑性铰的数量不变,只是在楼层的分布发生改变。相比传统的阻尼器参数设计方法,基于性能的TID系统优化设计不仅能降低主体结构的位移和层间位移角,而且能减少非线性结构的塑性铰数量和塑性耗能,进而减少结构在大震下的损伤。

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.
