Abstract :
Composite steel-concrete slabs are structural elements composed of a profiled steel deck which acts as
a permanent formwork to the concrete topping. This layer is commonly reinforced with individual rebars
and an anti-crack mesh. The Annex D of the EN 1994-1-2 provides guidelines for the calculation of the
temperature of the steel components of composite slabs subjected to the standard fire. However, no
revisions were made to these calculation rules during the last years. This paper proposes a new method
for the estimation of the temperature of the parts of the steel deck and the rebars as well. The proposed
methodology is derived from numerical analyses using a 3-D finite element model, considering perfect
thermal contact between the materials.
