This paper is concerned with the study on dynamic behavior of actual building during earthquakes. The actual building consists of two structures. One of them is base isolated structure. Another is coventional structure. They are 3-storied reinforced concrete buildings with same scale and structure in order to compair the eqrthquake response. To find the difference of char acteristics response, We have carried out earthquake observations. The following results are mainly obtained from this study. 1) In the base isolation building, earthquake maximum response acceleration is reduced 1/5 at roof floor in comparison with the conventional building. 2) In the base isolation building, earthquake response acceleration at 1st floor is reduced to 50〜60% in comparison with the basement. 3) The value of stiffness and damping coefficient at base isolation story which was obtained from earthquake observation corresponde with the value of empirical formula.
