We compared earthquake vibration at various points of a seismic isolated building, and clarified its response characteristics, in the following way. l) Isolation system was effective for the base acceleration 5 gal or higher, suppressing the amplification of acceleration response (top) below O.6. 2) Lead dampers in the system were effective, even for low level of differential movement across the isolation floor (2.2mm). 3) The building's motion as observed was sufficiently simulated by introducing horizontal and vertical vibrations to a three-degree of freedom rigid-body model. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
