Bastian Ackermann Results RFEM RSTAB Structural Analysis & Design

I have modeled a single-span beam with several members. Why are the signs of the shear force distribution partially incorrect?

Answer

It is very likely that there will be no uniform staff orientation, see Figure 1.

Figure 01 - Shear force distribution without uniform member orientation

As soon as the member orientation is uniform (right-click on the member → "Reverse Member Orientation"), the signs of the shear force distribution also match, see Figure 2.
