How can I model a plane frame that is self-rigid and hinged to columns?

Answer

In this case, it is recommended to use nodal releases. They allow for a transfer of bending moments in the frame plane as a transfer of axial and shear forces to the columns.

The nodes to be released are the respective corner nodes with a moment hinge as a member hinge. The released objects are the horizontal members in the frame plane that are connected to the corner nodes.
