I have calculated a pre-deformed structure according to the second-order analysis with RF‑STABILITY and RF‑IMP. Why are the deformations of the CO smaller than the applied pre-deformation?
I have not succeeded in visualizing the pre-deformations in the rendering mode in FE‑LTB.I only see either the undeformed system or the stress distribution, but never the pre-deformation!
I am designing a two-hinged frame using FE‑LTB. I have defined the columns and the beam as sets of members.Why is the restraining moment of the beam in the columns not taken into account?
