We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi! Thanks for your suggestion. I will try it. For the meantime, I am encountering another problem. I hope you could help here also.

Although my load-deflection curves are somewhat similar to that of my reference study, I am not sure how I can know if my beam has crushed or not. Am I the one to set my own criteria to decide whether the beam fails? Right now, I can only think of steel rebar yielding as a criteria -- that is, if the steel rebar reaches its yield strength (400 MPa), then I will assume that the beam fails. The problem here is the steel rebar yields at around 49 mm in my model while it should yield at 35 mm based on my reference study. Because of this, I am unable to accurately determine the maximum deflection that my beam can experience.

What can I do to correct this? Do you have suggestions on how I can know when my beam fails? I have read something about utilizing stress tools but I do not quite understand how I can use them to know if my beam fails.Â
