Abstract

The behavior of simply supported reinforced concrete slabs in fire conditions and the influence of
certain parameters on their fire resistance is analysed in this paper. The influence of the slab span,
concrete cover thickness and the type of reinforcement scheme are analysed. All slabs are exposed
to standard fire ISO 834. The analyses are conducted by using the computer program SAFIR2016,
which is based on the Finite Element Method, and the simplified procedure given in EN 1992-1-2.
For the numerical analyses, two approaches are used: 2D-analysis, when the discretization is
performed with beam elements and 3D-analysis, when the discretization is performed with shell
elements. The 3D-analyses are performed for a meter width strip and for the real width of the slabs.
The width of the slabs is adopted to be the same with the span.
