Earthquake observation on a five storied RC building was carried out. Seismometers were set on each side and center of the first floor, fifth floor and soil. Using earthquake observation records obtained by the above seismometers, a parameter identification of a sway-rocking model was carried out. After identifying of stiffness and damping of this model, the following results are obtained. An identification process have a large effect on the estimation of stiffnesses and dampings of soil. Stiffnesses are identified fairly well but dampings, especially damping of rocking are estimated rather large. After investigating the reason of this discrepancy, it becomes clear that the further study should be required on the earthquake and soil-building characteristics.
