Abstract
High strength concrete (HSC) is being increasingly used in a number of building applications, where structural fire safety is one of the major design considerations. Many research studies clearly indicate that the fire performance of HSC is different from that of normal strength concrete (NSC) and that HSC may not exhibit same level of performance as NSC in fire. This paper discusses the performance of HSC under fire conditions. A comparison is made of the fire resistance performance of HSC column with that of NSC column. The various factors that influence the structural behaviour of HSC columns under fire conditions are discussed. Data from earlier experimental and numerical studies is used to illustrate the impact the concrete (material) mix design and structural detailing (design) has on fire performance of HSC systems. Finally, design solutions are presented for mitigating spalling and enhancing fire endurance of HSC columns.
