Good morning everyone,
I am working on a beam-column joint in reinforced concrete using ANSYS with a nonlinear concrete model. I am following the example provided in the ANSYS manual, "Chapter 54: Reinforced Concrete Joint Analysis," where a force-displacement graph is shown, highlighting both the hardening and softening phases.

My goal is to achieve a similar result for my specimen. However, I am unable to reproduce the softening phase, even though I have used the same settings as described in the example.

Could anyone provide some advice? I’m attaching my results: the blue curve represents the experimental data.

Thank you very much in advance!
