However, the SIS general is chiefly effective only to the horizontal motion, not effective for the vertical motion, by occasion of the following. #1: The maximum acceleration of the vertical motion is 1/2-1/3 smaller of the horizontal motion. #2: Even if the vertical motion is input to the building, the structure is not strongly damaged generally and does not harm the human life. #3: An effective three dimensional (3D) seismic device has not be developed. It is necessary in the future to achievine the following performance for the vertical motion for improvement of the seismic safety and the habitability. #1: The accommodations in the computer facilities, the museums, and medical facilities receive neither fall nor damage, etc. in an earthquake. #2: Comparatively small turbulence vibration should be prevented for BCP of precision equipments in such as power plants and the semiconductor factories. #3: For a residence use, the severer specification of the structure and protection of property are needed. The demand performance is the following items in a controlled device. #1: Device which is easy to maintain, and is not necessary to substitute basically #2: Device not greatly influenced at temperature #3: Device whose performance is reproducible and whose modeling for design analysis is easy #4: Device effective against the vibration from very small amplitude to large amplitude #5: Device that can be controlled against rocking motion of building We propose 3D seismic base isolation system for applying to a general building. The proposed 3D seismic isolation device consists of laminated rubber bearings as horizontal isolation device and air spring as vertical isolation device. A rocking suppression device with an oil damper is used to control a rocking vibration. In this paper, building concept of applied 3DSIS to a general building would be introduced.
