A stiffened plate buckling model for calculating critical stress of distortional buckling of CFS beams [PDF]
International Journal of Mechanical Sciences, 2016 Abstract This paper presents a stiffened-plate buckling model for calculating the critical stress of distortional buckling of cold-form steel (CFS) channel-section columns. The model is the further extending of the buckling model we developed recently for beams (International Journal of Mechanical Sciences 2016, 115/116: 457–464) to columns.
