Abstract During the 2011 off the Pacific coast of Tohoku Earthquake, many suspended ceilings and other suspended equipment fell down causing fatal accidents even in Tokyo, while relatively minor damages were observed to the structures. To mitigate such severe damage to the ceilings during earthquakes, new seismic design code for suspended ceiling system was issued by the Ministry of Land, Infrastructure, Transport and Tourism. However, the mechanism has not yet been understood clearly yet why and how the ceilings fell down due to the earthquake motion. A new research project started to clarify the collapse mechanism of wide-area ceiling system and to develop its countermeasures. Full-scale shake-table experiments of the wide-area ceiling system in a steel gymnasium was conducted as the first phase in 2014. This paper outlines the test plans and the observed global responses of the structural members and the ceilings.
