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.

Automated summary

This article reviews various methods for predicting the fire resistance of reinforced concrete (RC) columns and examines the influence of structural, material, mechanical, and heating-related parameters on their fire resistance. The feasibility of these methods in determining the fire resistance of RC columns is also discussed. The role of spalling of concrete on fire resistance is emphasized, and a systematic review of experimental data on fire resistance of RC columns is conducted. Parametric variability and experimental discrepancy are studied for determining the fire resistance of RC columns.
