Abstract
Japan has two decades of experience in designing and constructing baseisolated building structures. Construction has increased significantly since the 1995 Hyogoken-Nanbu (Kobe) earthquake, having reached over 150 annual construction projects. Many new developments and refinements have been made in the material, device, design, and construction of these structures. This paper summarizes recent design and construction of base-isolated building structures in Japan, including statistical data with respect to the common usage as well as the number of new projects.
