First, define a reference point for one end of the beam and define the moment for it, and fix the other end. Select the Total forces and moments (TF) variables from the Field Output Requests in the step module. Run the job. To plot the moment-curvature diagram, plot the TF of the reference point and UR3 (the UR number depends on your moment direction). Then, use “Operate XY data” and combine the two plots.

Hello Sir, The method you suggested gives the moment-rotation angle plot. How do you convert it into moment-curvature plot? I know curvature is the derivative of the rotation angle over the arclength. But, we are specifying one reference point on the outer edge. Hence, how do I take derivative of the rotation angle to convert a moment-rotation angle plot to moment-curvature plot?
