yes John,
I know of the *release option. But this option completely release the chosen force component.

I am trying to model compressed steel columns with partial continuity connections at mid-height.
I guess that a proper modeling scheme may be two elastic beam elements linked by a "hinge" connector with non-linear behavior. Displacement of the hinged node can then model imperfection.
Anyone...
