Testing and design of cold-formed high strength steel square hollow section columns
Abstract An experimental and numerical investigation into the flexural buckling behaviour of cold-formed (CF) high-strength steel (HSS) square hollow section (SHS) members is reported in this paper. A series of 12 flexural buckling tests were conducted on S700 and S900 CF SHS columns. Finite element (FE) models were developed to simulate the experimental observations, which were utilized in a parametric study encompassing a broader range of steel grades and specimen geometries. Subsequently, the current buckling curves in European, North American, and Australian codes was evaluated through reliability analyses. Meanwhile, the effective width method (EWM) and the modified generalized slenderness-based resistance method (GRSM) were compared for slender cross-sections. According to the results of reliability analyses, the modified buckling curves were proposed for CF HSS SHS columns.
Highlights Experimental tests on cold formed high strength steel columns and tensile coupons have been carried out. Numerical modelling validation and subsequent parametric study has been performed. Effect of corner radius on the column strength has been quantified. Design proposals have been made and modifications to current design codes have been proposed.
