Question

I have modeled a deep single-span beam as a surface. Why are there no bending moments displayed after a successful calculation?

Answer

The moments mx and my (Figure 01) refer to the local surface axis system and would therefore only occur in the case of loading in the local z‑direction of the surface.

In this case, the solution is to create a result beam in the direction of the desired single-span beam and to obtain the bending moments from the corresponding member internal forces (Figure 02).
