This paper presents an experimental investigation into the structural behaviour of eccentrically loaded concrete filled, thin walled, steel tubular slender column with tab stiffeners (CFST). The primary parameters studied through the experimental work are load eccentricity and type of stiffeners. Three different types of stiffeners used in this study are longitudinal stiffeners of 10mm height, longitudinal and tab stiffeners of 25mm height and longitudinal and extended tab stiffeners at 40mm. The effects of the stiffeners on the structural behavior were investigated experimentally using 26 specimens of slender CFST, loaded with eccentricity ranging from 0 mm to 60 mm. It was observed that all specimens failed mainly by overall buckling and, the compressive strength and bending strength of the specimens decreases as the applied load eccentricity increases.
