An optimum selection of alloy for aluminium structures exposed to fire

An optimum selection of alloy for aluminium structures exposed to fireAnalytical methods for calculating fire resistance of aluminium structures, specified in (HRN) EN 1999-1-2, are presented in the paper.Since aluminium as a material loses its mechanical properties at lower temperatures compared to steel, the correct selection of aluminium alloy in terms of minimal reduction of mechanical properties is essential for satisfying fire-related requirements.For clarifying the influence of selecting aluminium alloy for obtaining an optimum fire resistance, a parametric analysis is presented to demonstrate the influence of aluminium alloy on the design fire resistance of a loadbearing aluminium column.
