Conventional vibration absorbers, e.g., a classical tuned mass damper, may be not efficient in simultaneously controlling the seismic response of adjacent high-rise buildings. In this paper, a novel passive vibration control system, denoted as Multi-Tuned Liquid Column Damper-Inerter (MTLCDI), is developed to control the seismic response of adjacent high-rise buildings. Two different configurations of this system, namely inter-story MTLCDI (IS-MTLCDI) and inter-building MTLCDI (IB-MTLCDI), are proposed, and related mathematical models are developed to investigate the seismic performance of MTLCDI. A case study project comprising two adjacent high-rise buildings equipped with the proposed system and subjected to ten earthquake records with various frequency characteristics is considered. Performance-based parametric optimization of the MTLCDI systems is performed through two distinct constrained multi-objective optimization problems via genetic algorithms, wherein peak absolute accelerations and inter-story drift ratios of the two adjacent buildings are selected as performance indexes. The mitigation effects of optimum IS-MTLCDI and IB-MTLCDI on earthquake-induced vibrations are scrutinized, with emphasis placed on the effects of natural frequency ratios between the two host structures. The results indicate that, when the two buildings have distinct natural frequencies, both IS-MTLCDI and IB-MTLCDI outperform inter-building single TLCDI as well as other vibration absorbers in terms of seismic vibration control of absolute acceleration and inter-story drift ratios. Under most natural frequency ratios, the IS-MTLCDI achieves a larger response reduction than IB-MTLCDI. Nevertheless, when the differences between natural frequencies of adjacent buildings are significant, applying an IB-MTLCDI may be preferable due to its satisfactory mitigation effects combined with ease of installation.

传统的减振器，例如经典的调谐质量阻尼器，在同时控制相邻高层建筑的地震响应时可能效率不高。在本文中，开发了一种新颖的被动振动控制系统，称为多调谐液柱阻尼器-惯性器（MTLCDI），用于控制相邻高层建筑的地震响应。提出了该系统的两种不同配置，即层间MTLCDI（IS-MTLCDI）和建筑物间MTLCDI（IB-MTLCDI），并开发了相关的数学模型来研究MTLCDI的抗震性能。考虑了一个案例研究项目，该项目包括两座装有拟议系统的相邻高层建筑，并经受了十次具有各种频率特征的地震记录。MTLCDI系统的基于性能的参数优化是通过遗传算法通过两个截然不同的约束多目标优化问题进行的，其中选择两个相邻建筑物的峰值绝对加速度和层间漂移比作为性能指标。仔细研究了最佳IS-MTLCDI和IB-MTLCDI对地震引起的振动的缓解效果，重点放在两个主体结构之间的固有频率比的影响上。结果表明，当两座建筑物具有不同的固有频率时，IS-MTLCDI和IB-MTLCDI在绝对加速度和层间漂移率的地震振动控制方面均优于建筑物间的单个TLCDI和其他减振器。在大多数自然频率比下 与IB-MTLCDI相比，IS-MTLCDI的响应降低更大。但是，当相邻建筑物的固有频率之间的差异很大时，由于其令人满意的缓解效果以及易于安装的原因，可能最好使用IB-MTLCDI。
