We detected ground springs and damping factors in a sway-rocking model using micro-tremor and earthquake records at a soil-pile-structure interaction system. We used an equivalent linearization method in order to consider non-linearity of soil ground. Additionally, we compared foundation input motion detected by observation data and FEM analysis. Finally, we made earthquake response analyses with the detected ground springs and damping factors to evaluate accuracy of the sway-rocking model.
