Harnessing the concept of inertial amplification, an inertial amplifier coupled base isolator (IABI) is proposed in this paper. The seismic performance, in terms of story drift, base shear reduction, of this proposed inertial amplifier coupled base isolator has been compared with that of the classical base isolator (CBI) and inerter-based isolation system (Inerter-BI). A thorough analytical study, implementing rationals of random vibration for harmonic and Gaussian white noise is conducted to identify the performance of the inertial amplifier coupled base isolator (IABI) in the frequency domain. Further, a numerical study is conducted to determine the story drift, base shear response in time-domain for the inertial amplifier based base-isolated structure and classical base-isolated structure for twenty-two real earthquake ground motions. The results elucidate the histogram of base shear and story drift reduction percentage shifts towards higher values for inertial amplifier coupled isolator compared to CBI and Inerter-BI. From both analytical and numerical study, it is observed that the seismic performance and response reduction capacity of proposed IABI is significantly 89.38% and 72% superior to the classical base isolator and inerter-based isolation system, respectively. This finding evidenced towards the supremacy of the inertial amplifier base isolator over the classical base isolator and inerter coupled base isolator in terms of seismic vibration control.

利用惯性放大的概念，提出了一种惯性放大器耦合基极隔离器（IABI）。已将这种拟议的惯性放大器耦合基础隔离器的抗震性能（如故事层漂移，基础剪切减小）与经典基础隔离器（CBI）和基于惯性的隔离系统（Inerter-BI）进行了比较。进行了彻底的分析研究，为谐波和高斯白噪声实现了随机振动的原理，以识别惯性放大器耦合基础隔离器（IABI）在频域中的性能。此外，进行了数值研究，以确定了基于惯性放大器的基础隔震结构和经典的基础隔震结构的层间位移，时域中的基础剪力响应以及二十二个实际地震地震动的时域。结果阐明了惯性放大器耦合隔离器与CBI和Inerter-BI相比，基本剪切的直方图和楼层漂移减少的百分比偏向更高的值。从分析和数值研究两者都可以看出，所提出的IABI的抗震性能和减震能力分别比经典的基础隔震系统和基于惯性的隔震系统分别高89.38％和72％。这一发现证明，在地震振动控制方面，惯性放大器基本隔离器优于经典基本隔离器和惯性耦合基本隔离器。可以看出，建议的IABI的抗震性能和减震能力分别比经典的基础隔震系统和基于惯性的隔震系统分别高89.38％和72％。这一发现证明，在地震振动控制方面，惯性放大器基本隔离器优于经典基本隔离器和惯性耦合基本隔离器。可以看出，建议的IABI的抗震性能和减震能力分别比经典的基础隔震系统和基于惯性的隔震系统分别高89.38％和72％。这一发现证明，在地震振动控制方面，惯性放大器基本隔离器优于经典基本隔离器和惯性耦合基本隔离器。
