Research development on the estimation of dynamic characteristics of multi-storied buildings considering soil-structure interaction have been made based mostly on either earthquake response observations or forced vibration experiments with very little on microtremor measurements. Stable parameter identifications using microtremor measurements are considered to be difficult, because the elastic deformation is insufficiently developed for low rise buildings. An identification method is proposed in order to estimate the dynamic characteristics of multi-storied buildings separately from the soil characteristics using the sway and rocking model. The proposed method was successfully applied on the estimation of dynamic characteristics, as well as the sway and rocking parameters of ten different buildings. Results were consistently stable, and the applicablity of the method was confirmed.
