Observation of the earthquake response of a base isolated building has been carried out for seven years. This building is a four-story reinforced concrete structure equipped with 25 natural rubber bearings and 12 steel dampers. More than 100 earthquake responses have been recorded. From the statistical study based on these records, the following results are concluded: (1) The response acceleration is sufficiently reduced; (2) The response reduction effect depends on the frequency characteristics of the basement; and (3) The maximum response of the base isolated building can be well predicted by the maximum velocity or the velocity response spectrum of the basement.
