Abstract

 Pre-stressed concrete hollow core slabs (HCS) are now progressively used
in commercial, industrial, and residential buildings due to their sustainability,
affordability, and adaptability. The performance of HCS units subjected to fire is
particularly difficult and is attributable to their unusual cross-section, which
features voids. Numerous investigations were executed on HCS at high
temperatures concerning the crucial temperature and failure mechanisms of both
concrete and prestressing steel. Fire performance is influenced by a number of
variables, including support condition, concrete aggregate type, slab thickness, fire
insulation and cover thickness for reinforcement, spalling accessibility, void cores
and size, and firing methodology. While a number of these variables have received
extensive research, some have been noted as potential contributory reasons for
failure, while others have received relatively little attention. This paper summarises
numerous experimental, numerical, and analytical studies about the attitude of HCS
vulnerable to fire in addition the building standards limitations to provide a valuable
reference for future researchers.
