abstract
During a fire, some types of concrete are known to be susceptible to a sudden detachment of the outer layer, known as explosive spalling, if a specific combination of influencing factors occurs. For a given reinforced concrete slab configuration, however, it is unclear which percentage of slabs can be expected to suffer from explosive spalling and whether possible spalling has a significant impact on the load bearing capacity and the deformations during fire. In this paper a methodology is developed in order to assess the probability of spalling and its effect on the deformations during fire exposure. A hydrothermal calculation method described in literature is combined with a full-probabilistic crosssectional calculation tool which allows to calculate the evolution of the mid-span vertical deflection during fire. The results indicate that for the investigated slab configuration the probability of occurrence of spalling is rather small (2.7%). However, when spalling occurs it has a significant impact on the deformations during fire, possibly even resulting in a premature collapse of the slab.
