The object of the invention is to provide a building (2), which prevents by its structure, a transmission of high-frequency oscillations, which are induced by a plane crash in the building interior or at least attenuates. This object is achieved according to the invention by a building (2), in particular a power plant building of a nuclear power plant, comprising at least one reinforced concrete side wall (4) and at least one reinforced concrete ceiling slab (12), wherein the ceiling slab (12) is mounted on a bracket (10). rests, which protrudes from the side wall (4), • the ceiling plate (12) from the side wall (4) by a gap (16) is spaced, • the cover plate (12) by at least one connecting anchor (20) shear-resistant with the console ( 10) is connected, and • the connecting anchor (20) is such that it withstands the associated loads in the static load case and earthquake load case, and that he crashes in the event of a load plane so that the ceiling plate (12) sliding on the console (10).
