We presented the suggestion concerned with bracing method for the improvement of the plastic deformation capacity of H-shaped beam. The primary concept of this bracing is attachment to beam, and non-sharing inner stress of beam, the control of the deformation of flange or web after buckling as elastical bracing. Then, the subject was local buckling behavior mainly. On the other hand, there is the case that the buckling behavior of H-shaped beam is local buckling consistented with lateral (torsional) buckling, and the lateral buckling produces a larage effect on plastic deformation capacity. In this paper, under the condition affected by local buckling and lateral buckling, the plastic deformation behavior of H-shaped beam with the presented bracing is investigated. This bracing is based on the above concept. And experimental and numerical analytical researches clarify the primary properties of this bracing.
