Abstract
Hollow structural steel columns, which are widely used in the construction of framed structures in industrial buildings, are often filled with concrete in order to achieve an increased load-bearing capacity. In recent years, high strength concrete is becoming an attractive alternative, to traditional plain concrete, since it increases the load-carrying capacity of hollow structural sections (HSS).. In this paper the fire performance of high strength concrete-filled steel hollow structural section (HSS) columns is presented for various types of concrete filling. A comparison is made of the fire resistance performance of HSS columns filled with normal strength concrete (NSC) and high strength concrete (HSC). The factors that influence the behaviour of HSC-filled HSS columns, under fire conditions, are discussed.
