2017 Journal of Structural Engineering  
An experimental and numerical study of the flexural buckling behavior of hot-finished 1 high strength steel (HSS) square and rectangular hollow section (SHS and RHS) columns is 2 described in this paper. A total of 30 hot-finished S460 and S690 hollow section column spec-3 imens have been tested in compression with pin-ended boundary conditions. Finite element 4 (FE) models have been developed to replicate the experiments, and employed in a subsequent 5 parametric study considering a range of

Based on the test and FE results, 6 the applicability of the current column design curves in European, North American, Chinese 7 and Australian structural steel design standards to hot-finished HSS SHS and RHS columns 8 has been verified by means of reliability analyses. 9
