鉄骨充腹ばりの横座屈に関する研究(その4) ―塑性設計ばりの均等モーメント下での横補剛間隔と回転容量の関係および補剛材の効果―

Abstract

In plastic design, it is essentially required that the structural components in a structure sufficient-ly deform sustaining their expected load until the structure reaches the overall failure. In thisreport, inelastic lateral buckling behavior and post-lateral buckling behavior of H-shaped beamsare discussed. Relationships between the spacing of lateral braces and rotation capacity underuniform moment are obtained experimentally and theoretically. Also discussed are relationsbetween bracing methods and positions in the cross-section to which braces are attached, and theeffects of the rigidity of braces on the rotation capacity of beams.
