Fire-induced spalling in reinforced concrete beams

A state-of-the-art review of experimental and analytical studies on fire-induced spalling in concrete structures is presented. The limitations in current code provisions related to spalling are discussed. A hydrothermal-based spalling model is applied to undertake parametric studies to investigate the effect of critical parameters on fire-induced spalling in reinforced concrete beams. The results of these studies show that fire scenario and concrete permeability largely influence the extent of fire-induced spalling in reinforced concrete beams. Research needed for improving the state-of-the-art on fire-induced spalling in concrete structures is highlighted.
