N2 - This paper clarifies the flexural buckling load of H-shaped compression members with lateral support at their half length and the required rigidity of the lateral supports. In this study, the braces used as lateral supports are eccentrically jointed to the compression members in their sections. The buckling load of the members with eccentric support is calculated by the energy method and the elastic eigen-value analysis, and then the braces are replaced by lateral and rotational springs. This paper evaluates the rigidity demand equivalent to immovable lateral supports and also confirms its effect using inelastic large deformation analysis.
