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

Question

Accepted Answer

The resulting surfaces displayed in RFEM refer to the smoothed internal forces. The design in RF‑CONCRETE Surfaces is based solely on the basis of the internal forces smoothed within a surface. Smoothing is not performed across the supported line. In this context, the shear force distribution shown in Image 01 may occur.
