Stainless steel in fire
The relatively sparse body of existing data on the behaviour of structural stainless steel at high temperatures suggests that stainless steel performs very well between 600 deg C and 800 deg C due to its strength and stiffness retention characteristics. This report summarises the findings of a 3.5 year European research project which studied the behaviour of a range of structural stainless steel solutions subject to fire loading. The project included tests on materials, members and connections, numerical analysis and development of design guidance aligned to the Eurocodes. It aimed to identify structural solutions which give a specified period of fire resistance without any fire protection applied to the surface of the steel. The temperature development in a range of load-bearing and separating element concepts designed to suppress temperature rise was studied. From a programme of tests and numerical analysis on RHS with slender (Class 4) cross-sections, more economic design guidance was derived. Long fire resistance periods were exhibited in fire tests on concrete-filled stainless steel RHS and hybrid stainless-carbon steel composite floor beams. Strength and stiffness retention characteristics for two austenitic grades not previously studied were developed through a programme of transient state tests. The behaviour of external stainless steel columns and stainless steel columns in open car parks subject to realistic fire loads was studied numerically. Tests on welded and bolted connections in fire enabled design guidance to be derived. An online design facility for predicting the fire resistance of cold formed stainless steel sections was developed.
