Buckling of stainless steel columns in fire

Abstract

The inherent corrosion resistance and elevated temperature strength retention of stainless steels lend them-selves to applications in buildings and structures where fire resistance is important. This paper examines the fire resistance design of stainless steels columns, and in particular focuses on the suitability of using the 0.2% proof stress f0.2 or the stress at 2% total strain f2 as the basic design strength parameters. Through analysis of FE generated column data, it is shown that the 0.2% proof stress is a more appropriate parameter as the basis for derivation of the buckling curves for stainless steel columns.
