Conversion moment-rotation to moment-curvature.

[parasismique]

Dear colleagues,

how to convert a graph from moment-rotation to moment-curvature.

I appreciate your help.

Curvature = Rotation / Lp, where Lp is the length over which the rotation occurs. This assumes the rotation is constant over Lp.
You can read any of the many publications in the equivalent plastic hinge length for columns, walls and beams to have a better idea
