Abstract

Since 1995, seismic isolation structures have been applied effectively to buildings whose superstructure is characterized to have a long fundamental period such as steel-framed and high-rise buildings. However, for logistics warehouses which are designed to be long span and a high floor height to create a large internal space, there is a possibility that such buildings will not deform as expected. This study proposes a response prediction formula for base-isolated building by using period ratio between the superstructure and the seismic isolation layer.
