Question

I design an eccentrically modeled wall beam in RF‑/STEEL Warping Torsion, which is loaded transversely with a distributed load. While the bending moments in the main program result in zero at the member start and member end due to the hinges, the RF‑/STEEL Warping Torsion add-on module displays moments at these locations, which incorrectly reduces the span moment.
How do I get the boundary moments equal to zero at this point?

Answer

Since the RF‑/STEEL EC3 or RF‑/STEEL Warping Torsion add-on module has its own solver, the eccentricities must also be considered here.

Therefore, it is recommended to adjust the support eccentricities within the add-on module, see Image 01.

Thus, the span moment becomes maximum and the boundary moments zero, see Image 02.
