Numerical simulation and analysis of stainless steel frames at high temperature

This paper presents a numerical modelling study investigating the response of stainless steel two-dimensional frame assemblies at elevated temperature that has not been subject detailed investigation to date. Finite elements models which capture combined effects material degradation with and interaction between individual are developed validated. The effect key behavioural parameters including type, i.e. sway non-sway, degree utilisation, grade heating profile is investigated through an extensive parametric modelling. A new set performance criteria in terms limiting deflection rate for non-sway frames fire established verified.
