Name: | Hinge response when yield point changes |
Description: | Behavior of a concentrated plastic hinge when the loading applied to a nonlinear frame object causes the yield point of the interaction surface to change position. |

This test problem evaluates hinge response when the yield point on the interaction surface changes. Since the yield point is defined by coordinates which couple axial and bending behaviors, post-yield changes in loading conditions will also cause the yield point to change.
For evaluation, a concentrated hinge is assigned to the fixed end of a cantilever beam. A moment and axial-compressive force are applied to the free end. Hinge response is then reviewed for a series of several load sequences which are assigned to a time-history load case.
