In the Great East Japan Earthquake, many suspended ceilings were damaged and fell down. If ceiling systems are attached to its surrounding walls and beams, in-plane compression strength of ceilings can be a primary factor of seismic design. By the results of compression tests, the strength is often limited by the buckling of ceiling as a composite plate. In this case, bending mechanical properties of ceiling system can be major factors of fragility against earthquakes. In this paper, bending stiffness and strength of steel furring suspended ceiling system are clarified by static bending tests.
