ELASTIC BUCKLING STRENGTH OF H-SHAPED BEAM-COLUMN WHEN BRACING IS ATTACHED AT MIDSPAN OF THE MEMBER
Relation between elastic buckling strength and bracing stiffness of H-Shaped member simply supported at both ends (Part 1)

Abstract

 This paper is concerned with the effect of the bracing stiffness on the elastic buckling strength of H-shaped members that are subjected to axial force, end moments and uniformly distributed load. The member is simply supported at both ends and discrete or continuous lateral bracing and torsional bracing are attached. The buckling equation is derived by using the Rayleigh-Ritz method. The relation between elastic buckling strength and bracing stiffness are presented when the member is subjected to axial force and end moments when the bracing is attached at the midspan of the member. The relation between the compressive force and the required bracing stiffness in order that the deflection and the torsional angle at the bracing point are zero and the equation to obtain the required bracing stiffness is presented.
