Statistical Review of the Fire Resistance of Concrete Columns

Fire resistance of a structural element is predicted by numerical, analytical and empirical methods while as codes mostly provide prescriptive guidelines for determining fire resistance of RC columns. Many of these methods are reviewed for examining the influence of structural, material, mechanical and heating-related parametric variations on fire resistance of RC columns. Further, the feasibility of these methods in determining fire resistance of RC columns is reviewed. Moreover, emphasis is given on reviewing the role of spalling of concrete on fire resistance of RC columns. Accordingly, a systematic review of experimental data on fire resistance of RC columns is performed. The parametric variability and experimental discrepancy are both studied for fire resistance determination of RC columns.
