This paper addresses enhancement of accuracy for the practical Kelvin-type modeling of a viscoelastic damper under seismic loading. The original rule to assign Kelvin-body's stiffness and viscosity was previously proposed by the writers. A new rule considers a case where the viscoelastic-damped structure possesses a high resonance frequency, and frequency contents of its response are close to those of the ground motion, rather than its resonance frequency. The performance of the model is examined by comparing the analytical results with those obtained from the accurate fractional-derivative constitutive rule. The new rule appears to substantially improve accuracy of the Kelvin-type modeling.
