CURRENT STATE OF SEISMIC-ISOLATION DESIGN
Japan has the highest number of seismic-isolation structures in the world. The number of such structures has been gradually increasing since the Hanshin-Awaji Disaster in 1995. It is the main reason that seismically isolated buildings have shown good performance during and after earthquakes. As people are becoming aware of the benefits of the seismic isolation system, it is being accepted more, in order to maintain structural safety and functionality during and after earthquakes. Items for life safety, property value, and maintaining functionality should be satisfied in the performance level of protection of buildings against big earthquakes. This system is the appropriate earthquake-resistant method in consideration of satisfying these three items, and positive in the design of structures, such as houses, hospitals, and high-rise buildings, then in retrofitting. The current state of seismically isolated structures and recent problems on the design for seismic isolation systems are discussed here.
