The governing equations for the analysis of the steel frames with local deformation of beam-to-column connections, that is, the out-of plane deformation in the column plates caused by the forces from the adjacent beams, are derived from the principle of hybrid potential energy. The local deformation can be dealt with independently of the shear deformation in the joint-panel. To demonstrate the applicability of this method to steel frames, two examples were analyzed. In addition, it is shown that to employ the different form of panel moment definition leads to the different form of compatibility condition around the connection. The basic equations of the plastic hinge method can, also, be derived from introducing the plastic condition at the plastic hinge through the Lagrangian multiplier technique.
