[SAP2000] how to make Moment-Curvature diagram?

[kusumoaji]

i make a model using SAP2000, analyzed by Time History - Nonlinear case.
after that, i want to make Moment vs Curvature diagram of Beam and Column.

my question: how to make moment - curvature of beam/column?

can i use "Display> Show Plot Function " and take Moment (M33) of frame (beam/column) for Y axis, and take Joint rotation (Displ - RY) as X axis?
can we assume rotation of end joint as curvature?

Your comment is very appreciated..

No.

For more information how to solve it look at chapter 6 in this book

I research this topic for a master class, in SAP2000 v14
You can use easily the models of Hognestad or Mander to do
the diagram Moment-Curvature or even define a new model of
stress-strain.

I made a short guide in this topic taking the model of Hognestad, but
now I added some steps for Mander.

Heres the file :
