Assign Moment-Curvature curve to plastic Hinge?
Good morning, In OpenSees it is possible to implement the "Plastic Hinge" concentrated plasticity model, and when doing the nonlinear analysis, the user enters the idealized moment-curvature (according to CalTrans)?

We have 2 types of lumped plasticity:
Lumped in a finite length using moment-curvature (curvature will be integrated by the FEM code in the finite length of the plastic hinge)
Lumped in a zero Length using moment-rotation (you have to input the rotation as a curvature integrated over the plastic hinge length, because now you don't have this physical length in your model)
