Many buildings in the Tohoku and Kanto area were strongly shaken during the Great East Japan Earthquake, March 11, 2011. These results are precious data, since the response-control technologies are relatively new and very few systems have been validated through actual earthquakes, there has been some desire to determine their true capabilities. In this paper, dynamic properties of a high-rise base-isolated building are focused. Modal properties of vibration period, damping ratio, and participation vectors are identified, by using the linear and nonlinear system identification techniques. The responses are compared with the hypothetical case that the superstructure had been fixed to the ground, and benefit of base-isolation is clearly demonstrated.
