Abstract
The local buckling behaviour and design of stainless steel plates in fire are investigated in this paper. Finite element models of stainless steel plates able to mimic their response in fire are created
and validated against experimental results from the literature. Parametric studies are then performed and the results are utilised to assess the current design provisions set out in the European
structural steel fire design code EN 1993-1-2; shortcomings in the prediction of the local buckling
response of stainless steel plates in fire are revealed. A new effective width based design approach
able to reflect the variation in strength and stiffness of stainless steel at different temperature levels
in the determination of the local plate slenderness and thereby the ultimate resistances of stainless steel plates in fire is put forward. The proposed approach is shown to provide significantly
higher levels of accuracy and reliability relative to the current provisions in EN 1993-1-2 for a
wide range of plate slendernesses, elevated temperature levels, stainless steel grades and loading
conditions. Incorporation of the proposed design approach into future revisions of EN 1993-1-2 is
recommended
