I use RF-/STEEL Warping Torsion 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?

Accepted 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 &quot;1.7 Nodal Supports&quot; of RF&#8209;/STEEL EC3 (see Image 01).After this change, the span moment becomes maximum and the boundary moments zero (see Image 02).
