H-shaped steel beams connected to steel dampers are subjected to compressive axial forces in addition to flexural moment, so that its buckling behavior is
more unstable than that to only flexural moment. On the other hand, it is effective for continuous braces to prevent the lateral bucking of H-shaped beams. In
this paper, the lateral buckling behavior for H-shaped beams with continuous braces under flexural moment and compressive axial force is clarified, and
elasto-plastic lateral buckling stresses of the beams or lateral stiffing force and rotational stiffing moment of continuous braces are evaluated by the energy
method and numerical analyses.
