近年来，为了提高日本的地震安全性，隔震系统建筑变得普遍。然而，一般的隔震系统主要仅对水平运动有效，而对垂直运动无效。未来，我们有必要开发抗垂直运动的装置，以确保抗震安全性和居住性的提高。为此我们开发了适用于一般建筑的三维隔震系统。它由板式橡胶支座作为水平隔震装置和空气弹簧作为垂直隔震装置组成。带有油阻尼器的摇摆抑制装置可以控制摇摆振动。采用三维隔震系统的建筑于2011年3月3日竣工。本文报告了地震观测记录的观测记录、系统识别和模拟分析。并通过分析地震观测记录，证实了三维隔震系统的地震特性和功效。
The seismic isolation system building becomes general to improve the seismic safety in Japan, recently. However, the general seismic isolation system is chiefly effective only to the horizontal motion not for the vertical motion. In the future, it is necessary that we achieve developing the device against the vertical motion for securing the improvement of the seismic safety and the habitability. And so we have been developed the three-dimensional seismic isolation system for applying to a general building. It consists of laminated rubber bearings as horizontal isolation device and air springs as vertical isolation device. The rocking suppression device with oil dampers can control a rocking vibration. The building using the three-dimensional seismic isolation system was completed on March 3, 2011. In this paper, we report the observation record, system identification and simulation analysis of earthquake observation records. And by analyzing earthquake observation records, we confirm the seismic characteristics and efficacy of the three-dimensional seismic isolation system.
