In Japanese moment resisting steel frames, H-shaped beams are rigidly connected to the box sectional columns which have high fork restraint against lateral buckling deformation of beams subjected to flexural moment. On the other hand, most of beams in frames are connected with continuous braces which are effective to prevent the lateral buckling. In this paper, the equation of the elastic lateral buckling load for H-shaped beams with fork restraint and continuous braces are developed. Elasto-plastic lateral buckling stresses and lateral stiffing force and rotational stiffing moment of continuous braces are evaluated by the energy method and numerical analyses.
