  • Fire and Concrete StructuresCement

    Figure 5 shows the effect of fire on the resistance of a simply supported reinforced concrete slab If the bottom side of the slab is subjected to fire the strength of the concrete and the reinforcing steel will decrease as the temperature increase However it can take up to three hours for the heat to penetrate through the concrete cover to the steel reinforcement As the strength of the steel reinforcement decreases the moment capacity of the slab decreases When the moment capacity of the slab is reduced to the magnitude of the moment caused by the applied load flexural collapse will occur It is important to point out that duration of fire until the reinforcing steel reaches the critical strength depends on the protection to the reinforcement provided by the concrete
