Question:
My results of the calculation with Torsional Warping are implausible. What could be the reason?
Answer:
First of all, it would be reasonable to check the boundary conditions for the design again. This includes, among other things, the selected load introduction, checking the transverse stiffeners, and the transitions between the members. It is also useful to check the analysis method without the second-order analysis due to large rotations.
However, it is also particularly important that RFEM requires an FE mesh distribution for the warping torsion.
You can check the FE mesh settings and the graphical display of the member FE mesh.
