The inerter-based damping system, renowned for its superior mechanical properties such as mass amplification and damping enhancement, has garnered significant research attention, resulting in diverse configurations. Differences in frequency dependence among these configurations yield complementary characteristics in response control. By leveraging the frequency dependence, damping enhancement can be maximized for diverse control demands. In addition, analytical studies reveal that conventional theoretical models underestimate control performance by neglecting the physical mass of the inerter. An improved model accounting for this effect is developed and its effectiveness verified through shaking table tests.
