In the design in Völbkrafttorsion I receive tensile forces instead of compressive forces in a support. Where is the problem?

Answer

The preset bearings in warp torsion need to be controlled and adjusted as they hold the respective set of bars at the start and end nodes in the local x-direction. Thus, the support "hangs" in the upper bearing and it is calculated a tensile force and possibly found no stability problem. Please release the bearing at the head of the column in local x-direction.
