Abstract
Composite concrete filled steel tube columns are increasingly used for high-rise building structures, owing to their excellent structural performance such as superior load-bearing capacity, high ductility, good energy dissipation and fire behaviour which arises from the combination of the two different materials in the structure. Composite structures exploit the characteristics of steel and concrete; steel with its high tensile strength and ductility and concrete with its high compressive strength and stiffness. In general, concrete filled composite columns with circular hollow sections (CHS) have the advantage over columns with other section shapes due to the circular cross sections providing a uniform confinement to the concrete core.
