Abstract :

This paper will address the future trends in the use of high strength steel and composite steel-concrete structures in construction. Future infrastructure is faced with the challenge of ever-increasing spans of bridges and heights of building structures. One of the most efficient methods to address this challenge is in the implementation of higher strength steels and higher strength concretes. This paper will trace the developments of both steel and steel-concrete composite structures over the last century and the material developments that have been made in steel and concrete strengths over that time. These developments have influenced the development of steel and steel-concrete composite systems and further contributed to the innovative bridge and building solutions over that period. The paper will highlight issues associated with serviceability, strength, stability, and ductility of high strength steel and composite structures. The applications and research in these areas will be addressed and the developments in the area of codification in international standards will also be presented with particular attention to American, Australasian and European steel and steel-concrete composite construction bridge and building standards. The paper will conclude by forecasting what the challenges for future infrastructure will be and how the implementation of both high strength steel and steel-concrete composite structures will be aligned to this future. Existing and future research in the area of high strength and very high strength steel will be summarised and typical applications from the construction industry illustrating the advantages will be highlighted.
