Elastic Local Buckling Strength of Tapered H-Shaped Cantilever Beams

Abstract:

The purpose of this paper is to investigate the elastic local buckling strength and the behavior of tapered H-shaped beams under stress condition of cantilever beam. The analyses were conducted by separating H-shaped beam into two plate elements (web and flanges). From the results of analyses, authors evaluate elastic local buckling strength of each plate element, and clarify the several effects of tapered shape by comparing buckling strength and the behavior of tapered H-shaped beam with uniform H-shaped beam. In addition, authors examine coupled buckling of the two plate elements and confirm that the evaluations can be appropriate in case of coupled buckling.
