Abstract

Stainless steel is increasingly used in construction due to its corrosion resistance, ease of maintenance, aesthetics and fire resistance. In spite of these benefits, its application in structures has been inhibited by a lack of design guidance that makes optimum use of its properties.

An extensive test programme was carried out on structural members and connections in stainless steel. The project concentrated on the most commonly used austeritic grades 1.4301 and 1.4401 and one duplex grade, 1.4462. One work package studied ferrite grades.

Numerical models were calibrated against these results, and then used to analyse the effects of a wider range of parameters than those tested. The existing design rules in the Eurocode covering design of structural stainless steel, ENV 1993-1-4, were compared against the experimental and numerical data. Where the rules proved excessively conservative, more economic design rules were developed.

The results of the project will lead to both revision and addition to the existing guidance in ENV 1993-1-4 as well as ENV 1993-1-2, the Eurocode covering design of structures in fire.

Key recommendations include:
-Less severe limiting width-to-thickness ratios for welded flanges and webs in compression, webs subject to bending and circular hollow sections subject to bending.
-Less severe buckling curves for major axis flexural buckling and lateral torsional buckling of welded I-sections.
-A new design approach for shear buckling and web crippling, closely based on the ENV 1993-1-5 rules.
-A method for predicting the fire resistance of beams and columns. nd columns.
