Abstract

When performing dynamic design, it's necessary to set an appropriate damping model. In the linear region, the setting of initial damping model affects the response. In the nonlinear region, the combination of initial damping model and hysteresis model affects the response. In this regard, we consider that its characteristics are unclear in the nonlinear region. In this paper, we study the effect of the difference both initial damping model and hysteresis model on the dynamic characteristics of the structure. We use the ARX model for calculate the natural frequency and damping ratio. The results showed the difference of response due to difference of damping model. Also the difference of variation of the natural frequency and damping ratio are shown.
