本文讨论了两节点表观质量装置在隔震结构中的应用，该装置称为惯性器，它产生的惯性阻力与两节点之间的相对加速度成正比。本研究采用一种由惯性元件与黏性元件并联组成的黏滞阻尼器。虽然使用VMD可有效降低相对响应，但由于惯性器直接将地面加速度传输到上部结构，因此之前的研究中出现了过大的地板响应加速度。这项工作检查的加速度降低效果的粘弹性元件串联VMD过滤掉地面运动加速度的高频分量。
This work discusses the application of a two-node apparent mass device, designated as an inerter, which generates inertial resistance forces proportional to relative accelerations between its two nodes, to seismic isolated civil structures. This study employs a viscous mass damper (VMD) consisting of an inerter and a viscous element in parallel arrangement. Although the use of a VMD is effective in reducing relative responses, previous studies have experienced excessive floor response accelerations because the inerter directly transmits ground accelerations to the superstructure. This work examines the acceleration reduction effect of a viscoelastic element arranged in series to the VMD for filtering out the higher frequency components of the ground motion accelerations.
