Standard fire resistance curves such as ASTM El 19 have been used for so long in structural fire practice. The issue with use of these curves that they do not represent real fire scenarios. As a result, the alternatives have been to either conduct experiments or find other tools to represent a real fire scenario. From this perspective, computational fluid dynamics (CFD) models developed to simulate a real fire scenario and to understand the structural responses on steel beams under elevated temperatures. The results obtained from these analyses were compared with those obtained in cases that used standard fire curves for its fire scenarios. A comparison of those models showed that relying on such standard fire curves might lead to a non-conservative design as compared to a real fire scenario; therefore, more research is required to determine the efficiency of using such standard curves in the field of fire protection engineering.
