The static design of reinforced concrete ceilings is mostly based on finite element calculations. If the calculated deformation is too big, a superelevation is carried out in order to optimize the thickness of the ceiling. The superelevation is achieved by setting parts of the formwork a fixed amount higher than the edge areas of the ceilings before concreting. In this contribution, a validation of various numerical methods and a new load approach for the deformation of concrete slabs by means of measurement results is shown whereas the focus is on the multistory support of ceilings, which have not arrived the full Young's modulus.
