This research is concerned with plastic deformation demand of energy absorption members in strong column type steel moment frames with eccentricity. In this paper, equivalent single mass and tri-degree of freedom system, which is based on generalized hardening hinge method, are proposed. And it discusses whether the system is available according to comparison with earthquake response of the systems and that of space frame models using fishbone-shaped frames.
