Lean duplex stainless steel ldss flat oval hollow columns under axial compression a finite element study

Abstract

Construction industry has been witnessing an increasing use of stainless steel members especially when there is a demand for higher strength to weight ratio good corrosion resistance low maintenance cost high ductility impact resistance fire resistance durability recyclability etc despite their higher material cost as compared to carbon steel However it has now become possible to offer cost effective stainless steel material with the introduction of a relatively new class of stainl
