After a suspended ceiling was damaged by great earthquake, a lot of people have been casualties by falling ceiling board, lighting fixtures and air-conditioning equipment, etc. Because damping ratio of iron anchor bolt is small and vibration of the suspended ceiling is not reduced in a short period of time, such an accident has happened. Currently, countermeasures to improve the earthquake resistance of the suspended ceiling is to fix the parts in the bolt and to install a reinforcing material in four directions of the hanging bolt. Then, there is a need for development of a using the new material, which is a lightweight, flame retardant, high heat resistance and high damping suspended ceiling having a seismic resistance and a seismic base isolation. The purpose of this study is to develop a ceiling by using the basalt fiber material hanging having the seismic resistance and the seismic base isolation. Basalt fiber material made of volcanic rock is the environment recycling material and, has a light weight, flame retardant, high heat resistance and high attenuation. In this study, using the new material, the design, analysis, testing and verification of the ceiling having the seismic resistance and aseismic base isolation.
