I use RF-/STEEL Warping Torsion for RFEM 5 / RSTAB 8 to design an eccentrically modeled wall beam, which is loaded transversely with a distributed load. While the bending moments in the main program are zero at the member start and member end due to the hinges, RF‑/STEEL Warping Torsion outputs moments there. Thus, the span moment is reduced incorrectly. How do I get the boundary moments to zero?
Answer:
Since the RF‑/STEEL EC3 and RF‑/STEEL Warping Torsion add-on modules have their own equation solvers, the eccentricities of supports also play an important role in this case.
Therefore, we recommend adjusting the support eccentricities. You can do this in Window "1.7 Nodal Supports" of RF‑/STEEL EC3.
After this change, the span moment becomes maximum and the boundary moments zero.
