摘要
调谐质量阻尼器（ＴＭＤ）是结构控制中发展起来的一种较成熟的控制装置。本文将ＴＭＤ减振技术运用于高架桥梁，建立了安装有ＴＭＤ的桥梁体系的分析计算模型，获得了其动力反应计算公式；探讨了ＴＭＤ装置对桥梁减震的有效性，并分析了ＴＭＤ动力参数对桥梁减震的影响。
he Tuned Mass Damper(TMD) is a perfect device for structure control. In this paper, the TMD vibration reducing technique is applied in the bridge with high piers and the analytical model of the bridge with TMD is proposed. Based on the dynamic response analysis of the bridge, the effectiveness of the TMD for reducing seismic response of bridge is discussed. Thereafter, the influence on the seismic response of bridge is analysed with the varing dynamic parameters of the TMD.
