H-shaped beams connected to steel dampers are subjected to the compressive and tensile forces in addition to the flexural moment, and then the buckling behavior of H-shaped beams under axial force and flexural moment is more unstable than that under only flexural moment. The previous studies clarified the local buckling behavior of H-shaped beams, and the maximum strength and the plastic deformation capacity of the beams are evaluated. In this paper, the lateral buckling behavior for H-shaped beams with the lateral bracing under flexural moment and axial force is clarified, and the lateral buckling stress is evaluated by the equivalent slenderness ratio.
