The tuned mass damper inerter (TMDI) is an enhanced variant of the tuned mass damper (TMD) that benefits from the mass‐amplification effect of the inerter. Here, a multi‐TMDI (MTMDI) system (comprising more than one TMDI) linking two adjacent high‐rise buildings is presented as an unconventional seismic protection strategy. The relative acceleration response of the adjacent structures triggers large reaction forces of the inerter devices in the MTMDI, which in turn efficiently improve the seismic performance of the two buildings. By addressing a real project of two adjacent high‐rise buildings connected by two corridors equipped with the proposed MTMDI system, the displacement‐, interstory drift‐, and acceleration‐based parametric optimizations are separately performed by employing Nondominated Sorting Genetic Algorithm II (NSGA‐II) under 44 ground motions from the FEMA P695 far‐field record set. It is found that the frequency content of the seismic input has strong impact on the MTMDI mitigation performance. Adopting realistic mass ratio constraints, the optimally designed MTMDI outperforms both conventional MTMD and single TMDI in acceleration control, while it is not much effective in mitigating the displacement response due to the highly flexible nature of the high‐rise buildings, in contrast to other literature studies generally focused on low‐to‐medium rise buildings.

应用于邻近高层建筑的多调谐质量阻尼器（MTMDI）的最佳设计和抗震性能

调谐质量阻尼器惰化器（TMDI）是调谐质量阻尼器（TMD）的增强型变体，得益于惰化器的质量放大作用。在此，提出了一种将两个相邻的高层建筑连接起来的多TMDI（MTMDI）系统（包含多个TMDI），这是一种非常规的防震策略。相邻结构的相对加速度响应会触发MTMDI中惰化装置的较大反作用力，从而有效地提高了两栋建筑物的抗震性能。通过解决一个实际的项目，即两个相邻的高层建筑之间通过两个配备了建议的MTMDI系统的走廊相连，位移，层间漂移，通过基于FEMA P695远场记录集的44次地面运动，采用非支配排序遗传算法II（NSGA-II）分别执行基于加速度和基于参数的优化。发现地震输入的频率内容对MTMDI减震性能有很大影响。与其他文献相比，采用现实的质量比率约束，优化设计的MTMDI在加速控制方面优于传统MTMD和单个TMDI，但由于高层建筑的高度灵活性，在缓解位移响应方面效果不佳。研究通常集中在中低层建筑上。
