Abstract
Recently, a green star rating system was introduced in Australia to promote sustainability in the construction industry (Green Building Council of Australia, 2009). Steel and concrete are the two most widely used construction materials. Sustainability in civil engineering construction can be achieved by using high strength steels as well as high strength concrete. High strength quenched and tempered (QT) and Very High Strength Steels (VHS) and high strength concrete with reduced amounts of Ordinary Portland Cement (OPC) can be adopted. This project will therefore consider the behaviour of concrete filled steel columns using higher strength steels with higher strength concrete incorporating low percentages of OPQ. The characterisation of residual stresses in high strength steel is important in understanding the buckling strength of concrete filled columns. Previous research on local and post-local buckling has been addressed for mild structural steel by Uy (2000) and Uy (2001) and these approaches will be augmented by using high strength steel and high strength concrete. In this paper preliminary measurements of residual stresses on the Kowari strain scanner at ANSTO, within the high strength steel joints will be discussed and future research plans will be presented.
