ABSTRACT
A steel-concrete composite column is a compression member which may be either a concrete-encased structural steel section or a concrete filled steel tube. The structural steel and concrete components resist the external loading by interacting together through the interface bond, or in special circumstances by the use of mechanical shear connectors. A great deal of theoretical and experimental work has been carried out on these types of column with a view to establishing their behaviour, characteristics and load-bearing capacities. The results and conclusions of these studies and investigations are summarized and presented here.
