摘要：

The objective of this study is to clarify the relations between the effective length of a flange portion and bracing stiffness of beam-columns subjected to axial force and bending moment. The member is restrained against sway and rotation at the center. The buckling equations are derived by using the Rayleigh-Ritz method, and the effective lengths of members are calculated, taking the bracing stiffness ratio, loading condition and coefficient R as analytical parameters. After discussing the relations between the effective length and bracing stiffness, the effects on the effective length of loading condition and coefficient R are described.
