Joint modeling with embedded rebars

Post by Lucy2012 » Sat May 22, 2021 1:22 pm

Dear STKO,
I am a new member and I am trying to model an RC joint. I saw the embedded rebar option and I tried to use it.
Unfortunately, the analysis does not run and I can't understand the reason. I need this model for my research, could you please check it? I know it is Saturday but I really need to get it done asap.
Thank you!

The main error comes from the beam-element type: it is an ElasticForceBeamColumn, while it should be a forceBeamColumn.

The other issue is that, in the first stage, the model is singular in the RotationY DOF. While in the second stage it is fine because the UX DOF is fixed with the applied displacement on top.
