Post-earthquake fires can result in rapid collapse of structures damaged partially due to prior earthquakes. An investigation is performed here on a seven-story fireproofed steel moment resisting structure designed for the life safety (LS) level of performance and a fire resistance rating (FRR) of 120 min based on the ISO834 fire. Introducing the specifications of fireproofing materials, the structure is first pushed to arrive at its target displacement at the LS level in order to detect the locations where the fireproofing materials have delaminated. The damaged structure is then subjected to three independent fire scenarios in stories 1, 4, and 7. The results indicate that when the fire is in story 1, 4, and 7, the FRR of the structure declines to 48, 39, and 37 min, respectively. A series of sensitivity analyses is also performed to understand how the length of delamination can effect on the FRR. To do this, the delamination lengths are changed to 150%, 75%, and 50% that of the pushover results, and then the PEF analyses are re-performed. The new analyses show that the changes made have no considerable effect on the overall FRR implying that the location of delamination has a dominant role in declining the FRR rather the extent of damage.
