The techniques for seismic design and seismic reinforcement of structural members in Korea have beendeveloped in a wide variety of ways, but research and technology on seismic retrofitting methods of nonstructural materials are very inadequate. In this study, we analyze ceiling system products of Japan which have seismic performance as a basic study on the development of non-structural ceiling system.
