Failure of large ceilings in large roof buildings during earthquakes is repetitively reported and intensive researches are now going in order to investigate the structural behavior of large suspended ceilings. In this article a simple numerical approach, in which the general behavior of ceilings are regarded as large panels in plane stress state, is proposed. The recursive effects, which stabilize the spatial position of the suspended ceiling, due to the gravity force are simply evaluated as a set of springs and superimposed to the plane stress stiffness matrix. Eigenvalue analyses and dynamic response analyses are carried out based on the formulation and validity of the formulation is discussed considering the numerical results.
