| Research Abstract |
A seismic peak response evaluation method for slip-hysteretic structure having a linear/nonlinear viscoelastic damper is proposed. Formulations to estimate equivalent vibration period and equivalent damping ratio of the slip-hysteretic structure subjected to random excitation are presented. The peak response evaluation method is based on equivalent linearization as well as spectrum modification and reduction, reflecting increase in equivalent vibration period and equivalent damping ratio.
