This paper deals with the application of fibre-reinforced concrete to enhance structural fire resistance. Materials, such as fibre-reinforced concrete, have good fire resistance properties and by properly designing the building elements, fire resistance, in the practical range, can be obtained. The properties of steel fibre-reinforce concrete are discussed. Examples of some fire resistance applications of steel fibre-reinforced concrete in buildings are illustrated. Results from studies on the fire resistance of concrete-filled steel columns show that the addition of steel fibres in concrete filling improves the fire resistance of steel columns and eliminates the need for external fire protection. The application of fibre-reinforced concrete in enhancing the fire resistance of high strength concrete columns is also discussed.
