The stainless steel are employed in a wide range of structural application such as in bridges, storage tanks, reinforcing bars for concrete structure, etc. Among the various grade of stainless steel, austenitic grades are generally popular in construction industry which has nickel content 8-11%. The demand for a new form of a duplex stainless steel leads to the development of Lean Duplex Stainless Steel (LDSS), which has a low nickel content of about 1.5%. The paper is investigates the buckling performance of different shaped lean duplex stainless steel hollow stub column with stiffener. Also performance of LDSS stub column compared with concrete stub column. A non-linear static analysis of LDSS stub column was studied using ANSYS workbench.
