Concrete filled steel tubular column comprising a hollow steel tube infilled with concrete has been used widely in high rise buildings.
Concrete filled steel tubular columns.
The cft columns can provide high capacity favorable ductility and large energy absorption capacity compared with the reinforced concrete structures.
Although modern design codes provide guides on concrete filled steel tubular members they do not cover their applications involving high strength concrete and high tensile steel.
In a concrete filled steel tube cfst column the steel tube provides confinement to the concrete core which permits the composite action among the steel tube and the concrete.
Concrete filled steel tubular cft columns have been used in many engineering structures such as bridges high rise buildings residential structures and other industrial structures.
Concrete filled steel tubular cfst columns are adopted in many structural applications especially for tall buildings bridges and large infrastructure due to their substantial structural and economic benefits.
