Introduction. The behavior of high strength thin-walled rectangular concrete-filled steel tubular (CFST) slender beam-columns under axial load and bending is influenced by many parameters such as the depth-to-thickness ratio, loading eccentricity, column slenderness, concrete compressive strength, steel yield strength, initial geometric imperfections and second order effects.High strength thin-walled rectangular concrete-filled thin walled and high strength h beamHigh strength thin-walled rectangular concrete-filled steel tubular (CFST) slender beam-columns under eccentric loading may undergo local and overall buckling.
