Seismic Design for Improvement Construction Method of Ceiling of Existing Stations

摘要

The type of structural supports used for ceilings in stations differ from those used in other buildings. In order to evaluate the seismic performance of station ceilings, it is therefore necessary to understand the function of supporting parts in the structure, and to evaluate loads acting on the ceiling during earthquakes. Shaking table tests and analytical studies of existing suspended station ceilings were conducted, focusing on the function of supporting parts in the structure. Seismic design to be applied to the method of improving the ceiling of the existing stations so as to make it safer during earthquakes is proposed.
