a small confusion

Hi all,
In the general-purpose program, such as abaqus adina, there are some concrete models in the material libray. if we use them in the beam element,I also can get the result. So, what is the difference between the result and that we get using the fiber model and plastic hinge model?

Thank you very much!
Could you explain a little of the reason? I have a limited knowlege about the FEM, sorry!

you might want to read up on it doing some research.
maybe study the work on the nonlinear beam-column element by filippou.
