For a support that can only transfer compressive forces, tensile forces are also displayed. How is it possible?

Answer

In a result combination of your model, load cases acting alternatively ("or") are connected in such a way that they once have a positive and a negative effect. Negative factors in an RC can be problematic if the calculation is nonlinear: The failure of springs, tension members, etc. acts in the "wrong" direction and provides the corresponding results.

The RC results are combined from the existing results: if a support has compressive forces in a load case, the value is converted by the minus sign in the combination criterion and applied as a tensile force.

Remedy: Define the load cases that should act negatively in the combination criterion as new load cases with a negative load.
