I have modeled a steel frame with fiber elements.
I need to find the plastic hinges length. I think the only way is to get the stress at both ends of the fiber and do some math calculations based on the distribution function. I appreciate if someone could help me with the theory, introducing references.
Is there any way to do it directly as an output or something?
Thanks in advance
no. and you are probably have to use some finer discretization of the elements using displacement beam column elements or continnum elements to find the hinge length.
