A sloping ceiling produces a response in the direction out of the ceiling plate surface only with horizontal force, so the mechanical properties are more complicated than with a horizontal ceiling, and quantitative grasping is difficult. Knowledge and experimental results are also limited, therefore, proper seismic design methods for sloping ceilings are not well established. The authors quantitatively grasped the mechanical characteristics of the sloping ceiling by adopting a ceiling method, that can simplify the horizontal force transmission path by using a diagonal member that directly connects the ceiling plate and the floor slab of the building.
