FDS Versus En-Models: A Comparison between the Heskestad Model from EN and CFD Results

Since FDS simulations of real fire scenarios are time-consuming, parametric studies are to be avoided, and it is worth investigating whether an alternative analytical model can predict the structural impact of the fire load with the same accuracy. This experimental study is designed to reflect the conditions of a tall building with a rather high steel structure level (starting at 11m) and low fire level (car fire at 1.5m). For this featured project, the difference is investigated between several car fires and the localised fire scenarios from annex C of EN 1991-1-2 (Heskestad model).
