An optimum selection of alloy for aluminium structures exposed to fire
Abstract
Analytical 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 load-bearing aluminium column.
