Abstract
Pre-stressed concrete hollow core slabs (HCS) are now progressively usedin commercial, industrial, and residential buildings due to their sustainability,affordability, and adaptability. The performance of HCS units subjected to fire isparticularly difficult and is attributable to their unusual cross-section, whichfeatures voids. Numerous investigations were executed on HCS at hightemperatures concerning the crucial temperature and failure mechanisms of bothconcrete and prestressing steel. Fire performance is influenced by a number ofvariables, including support condition, concrete aggregate type, slab thickness, fireinsulation and cover thickness for reinforcement, spalling accessibility, void coresand size, and firing methodology. While a number of these variables have receivedextensive research, some have been noted as potential contributory reasons forfailure, while others have received relatively little attention. This paper summarisesnumerous experimental, numerical, and analytical studies about the attitude of HCSvulnerable to fire in addition the building standards limitations to provide a valuablereference for future researchers
