Stress-strain curves of steel and aluminium exposed to natural fires
conference paper
The temperature-dependent reduction factors on the yield stress in codes for steel structures, ky, are derived using a constant heating rate and a constant stress, where the influence of creep is implicitly taken into account. This paper considers the material properties of steel and aluminium on the basis of a Natural Fire Safety Concept, where heating rates and stresses are possibly non-constant in time and the influence of creep may be different. The paper shows that a non-constant heating rate and stress in time significantly influences the critical temperature in some cases.
