Dear colleagues,
For modelling the RC column considering inelastic buckling of reinforcement. Authors use force-based Frame Element (two force-based elements).
Are these two force-based elements modeled by distributed plasticity (nonlinear beam column) or the combination of two formulations (distributed plasticity and concentrated plasticity) ?!
I appreciate your help my colleagues.
Force-based Frame Element ?!

Re: Force-based Frame Element ?!
The force-based element is based on a distributed plasticity approach. You can find more detailed information about the formulation here:'
