**3. Parametric Study**

In this section, parametric analyses will be performed to investigate the effects of CBIS parameters on structural seismic mitigation. The mitigation effect is represented in terms of the moduli of displacement and force frequency response function at the resonant frequency. Three arguments, namely the inertance–mass ratio μ, stiffness ratio κ, and additional damping ratio ξ, vary to study the control effect of a CBIS damper. The domain of these arguments is determined mathematically without considering practical aspects.
