摘　　要：为提升调谐液体阻尼器(TLD)的有效性和鲁棒性,提出一种基于双模态控制的双调谐隔震液体阻尼器(ITLD)设计方法。针对两自由度结构,以双模态为控制目标,建立了附加ITLD的结构简化力学模型,并基于该力学模型进行结构模态分析,提出了具有双模态控制优势的ITLD空间位置确定方法。并对该模型进行了参数分析和频率响应分析,分析表明ITLD在控制效果和鲁棒性方面具有显著优势。基于以上参数分析结果,结合主结构的模态特征,进一步提出了基于双模态控制的ITLD参数设计方法。以安装ITLD的典型高层建筑为例,对该结构进行了动力时程分析。结果表明:所提出的ITLD装置位置确定方法与多模态设计理论可以实现对高层结构的双模态控制,并有效抑制结构的位移和加速度地震响应;相比于传统的TLD,采用ITLD可以为结构提供一种强鲁棒性的减震措施。To improve the effectiveness and robustness of tuned liquid damper(TLD),a dual-isolated tuned liquid damper(ITLD)design method by employing dual-mode control was proposed.Oriented by the dual-mode control target,the simplified structural mechanical model with additional ITLDs was established,based on which the modal analysis was carried out and the corresponding installation method with the advantages of dual-mode control was proposed.The systematical parametric analysis and frequency response analysis were performed.The analysis shows that ITLD has significant advantages in control effect and robustness.Based on the analysis results and combined with the modal characteristics of the primary structure,the dual-modal-based parameter design method for ITLDs were further established.Finally,taking a typical high-rise building with ITLD as an example,the dynamic time history analysis was carried out.The results show that the proposed installation method and design theory of the ITLD can realize dual-mode control of high-rise structures and effectively suppress the structural seismic responses of displacement and acceleration.Compared with the traditional TLD,ITLD can provide a strong robust solution to the seismic response control of high-rise buildings.
