Post-fire Performance of Composite Columns Made with High Performance Steel
High performance steel is defined as any steel which has good properties in tensile strength, toughness, weldability, cold formability or corrosion resistance compared to the traditionally used mild steels. As two typical types of high performance steels, stainless steel and high strength steel are increasingly used in engineering applications in recent years. Fire can cause severe damage to structures. After a fire, the priority is to determine whether it can be reused. For composite columns made with high performance steel, the relevant research is very limited. Therefore, this research aims to investigate the post-fire performance of composite columns made with high performance steel, including stainless steel and high strength steel. Post-fire material properties of stainless steel, high strength steel and concrete will be investigated and stress–strain models will be proposed accordingly. Composite columns will be tested to study their post-fire behaviour. A simplified calculation method will be given for engineers to assess the post-fire properties of composite columns made with high performance steel.
