提出了高层建筑在长周期地震作用下的外伸调谐惯性质量电磁换能器(TIMET)系统。建议的支腿TIMET系统由支腿和TIMET部件组成。支腿阻尼器是一种新型的高层建筑消能减震方法，它将控制装置垂直安装在支腿和周边柱之间，以实现较大的耗能效果。而TIMET是基于调谐粘滞质量阻尼器(TVMD)的机理而发展起来的，它可以利用共振效应来提高吸能能力。然而，与粘性材料不同的是，TIMET的减振由电机提供，电机可以将机械能转换为电能。本研究的重点是通过数值模拟来研究高层建筑在长周期地震作用下支腿TIMET系统的结构控制性能和能量收集效率。
This paper proposes outrigger tuned inertial mass electromagnetic transducer (TIMET) systems for high-rise buildings subject to long period earthquake excitations. The proposed outrigger TIMET systems consist of the outrigger and TIMET parts. The outrigger damping systems have been proposed as a novel energy dissipation approach to high-rise buildings, in which control devices are installed vertically between the outrigger and perimeter columns to achieve large energy dissipation. While the TIMET has been developed based on the mechanism of the tuned viscous mass damper (TVMD) which can improve energy absorbing capability by taking advantage of resonance effect. However, instead of a viscous material, the damping of the TIMET is provided by a motor which can convert mechanical energy to electrical energy. The focus of this study is to investigate the structural control performance and energy harvesting efficiency of the proposed outrigger TIMET system for high-rise buildings subjected to long period earthquakes through numerical simulations.
