Abstract: Concrete infilled steel tubular section (CFST) is a composite column used for modern construction. CFST column system is the most successful system, and the confinement of concrete by steel tubular sections enhances in core’s strength. In recent scenario, stainless steel has been popular and widely used in many modern structural applications owing to their anti-corrosion resistance, durability, good in appearance and easy in maintenance. Stainless steel is quite expensive. To reduce the cost significantly stainless steel tube filled with concrete that is, concrete filled steel tubular (CFSST) is used and it is referred as composite material system. This composite material system has a wide application in column made up of concrete, to provide a better performance in terms of strength, stiffness, ductility and seismic resistance. Compare to all other composite material system. This paper discuss about the different types of stainless steel tubular sections, shapes used for stub column under axial loading, strength enhancement and the different modes of failures both experimentally & analytically of stub column.
