When modeling nonlinear frames, should I utilize nonlinear material properties or define frame hinges? What are the advantages and disadvantages of either approach?

Using "Display > Show Hinge Results" menu command, you can display moment-rotation curve for the entire section or stress strain-curves for individual fibers as shown in the figure below. For coupled P-M2-M3 hinges, the shape of the moment-curvature curve is defined by specifying the coordinates of critical points A, B, C, D, and E on the curve. This is not required for fiber hinges, because the moment curvature curve is obtained by integrating the response from individual fibers.
