This study proposes a hybrid control methodology that combines tuned liquid damper (TLD) and active mass damper (AMD) to suppress vibrations of multi-story building structure effectively. To this end, a dynamic model that can predict the vibration of multi-story building structure coupled with TLD and AMD is derived using the energy approach. The TLD that is mainly designed to suppress the main natural mode is developed with a multi-degree-of-freedom model to investigate the effect of the TLD on natural modes of structure numerically. The AMD is an active vibration controller that can suppress remaining resonant peaks, including ones resulting from the application of the TLD as well as other higher modes of interest. In this way, the proposed control can utilize the advantages of TLD and AMD simultaneously. We set up an experimental apparatus to verify the performance of the hybrid control methodology. The numerical and experimental results show that the proposed hybrid control method can successfully suppress the vibrations of multi-story building structure. The dynamic model derived in this study can also accurately predict the actual behavior of the system.

这项研究提出了一种混合控制方法，该方法结合了调谐液体阻尼器（TLD）和主动质量阻尼器（AMD）来有效抑制多层建筑结构的振动。为此，使用能量方法得出了可以预测多层建筑结构与TLD和AMD耦合振动的动态模型。使用多自由度模型开发了主要用于抑制主要自然模式的TLD，以数字方式研究TLD对结构自然模式的影响。AMD是一种有源振动控制器，可以抑制残留的共振峰，包括由TLD以及其他更高关注模式引起的共振峰。这样，建议的控件可以同时利用TLD和AMD的优势。我们建立了一个实验仪器，以验证混合控制方法的性能。数值和实验结果表明，所提出的混合控制方法能够成功地抑制多层建筑结构的振动。在这项研究中得出的动态模型还可以准确地预测系统的实际行为。
