Abstract
This paper presents an experimental and numerical study on the global buckling behavior of welded thick H-section columns of Q460GJ steel under axial load. The thickness of the flange and web is 42 and 25 mm, respectively, and the slenderness ratios of the columns vary between 49.8 and 85.0. Six specimens with different section sizes were tested, and their overall buckling results showed significant lateral displacement. Test results and design values calculated in accordance with several national design codes were compared. Finite-element models that considered the initial inflexion and residual stress were established. The comparison between the finite-element calculation and test results confirmed the reliability and accuracy of the model. A parametric study of the bearing capacity of thick H-section columns was conducted on the basis of their slenderness ratio and section size. Design recommendations were provided on the basis of the comparative analysis of the finite-element calculation results and design curves obtained using different codes. Recommendations for selecting column curve types in national codes is given when designing global buckling of welded thick H-section columns of Q460GJ steel under axial loading.
