contact with the substructure and is
only supported at its ends over the support length C, see equation 16 (figure
12 right). In this case the concrete beam at the edge or crack is loaded by its
deadweight and the flexural tensile stress σt at the bottom of the concrete slab
in the center of a slab edge or crack can be calculated by means of the
equations (in which a volume weight of 24 kN/m³ has been assumed for the
concrete):
