Why do I get a discontinuous zone in the distribution of internal forces? In the area of the supported line, the shear force VEd shows a jump, which does not seems to be plausible.

Answer

The outputs of surfaces in RFEM refer to averaged internal forces. The design in RF-CONCRETE Surfaces is based exclusively on the internal forces, which have been averaged within a surface. Smoothing is not performed across the supported line. In this context, the shear force distribution shown in Figure 01 may occur.
