https://orcid.org/0009-0000-8921-0140
Highlights Experimental tests on 1100 MPa steel welded I-section columns about minor-axis. A numerical parametric study considering various geometries. The intricate interplay between global and local buckling phenomena. Current codified buckling curves assessed via reliability analyses. Revised buckling curves for Q1100 welded I-section columns about minor-axis.
Abstract This paper presents an experimental and numerical investigation into the minor-axis flexural buckling behavior of Q1100 ultra high strength steel (UHSS) welded I-section columns. A total of 8 column specimens, spanning two different sections, were tested. Finite element (FE) models were developed to replicate the experimental observations, and these models were subsequently employed in a parametric investigation that encompassed a wider range of specimen geometries. Concurrently, a comprehensive evaluation of the buckling curves outlined in European, North American, Australian, and Chinese codes was performed through rigorous reliability analyses. Furthermore, this study conducted a comparative analysis between the effective width method (EWM) and the modified direct strength method (DSM) for slender cross-sections. Based on the outcomes of the reliability analyses, revised buckling curves are proposed, which are specifically aimed at enhancing the design provisions for addressing minor-axis flexural buckling in Q1100 ultra high strength steel welded I-section columns.
