- Abstract
- If a reinforced or prestressed concrete structure is exposed to a fire, then this structure will be gradually heated. When the heating is not uniform, and when the structure is prevented from moving, additional stresses will be produced in the structure. Furthermore, at high temperatures, the strength and deformation properties of the concrete, as well as those of the reinforcing or prestressing steel, will undergo changes. These changes affect the structural behavior and the load-carrying capacity of the building construction, and this capacity can be reduced to such an extent that the structure will fail.
