Observations drawn from various historical earthquake records show that fire incidents often happen after an earthquake for many reasons, including short circuits in electrical systems, rupture of the gas distribution systems, etc. Research indicates that damage to a building, whether total or localised, significantly impairs fire resistance. Analysis of damage data from earthquake-affected regions highlights the necessity for buildings to endure significant fires in specific situations. The extent of damage varies significantly among structural components based on size, material properties, delamination levels and extent of spalling. These insights indicate that various strengthening mechanisms enhance the fire resistance of structures. This article provides an overview of research on post-earthquake fire resistance. Studies on post-earthquake fire resistance of beams, columns, beam-column joints, steel, and reinforced concrete frames, and walls are analysed to draw significant conclusions. Earthquake-resistant building designs and various strengthening methods improve fire resistance. It is essential to consider the sequential effects of earthquake and fire loads on structures. Experimental analysis precisely replicates fire scenarios, while numerical analysis may produce slight differences in the obtained results.
