Concrete Filled Steel Tubular Columns

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 columns.

Nonlinear finite element analysis of circular concrete filled steel tube structures in struct. However the design guidelines for cfst columns with high strength materials and slender sections are still limited. 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. They are composed of an outer steel tube with an inner h section steel member and concrete and are classified into concrete filled circular steel tubes with embedded internal h section steel h cfcsts and concrete filled rectangular steel tubes with embedded internal h section steel h cfrsts.

The cft columns can provide high capacity favorable ductility and large energy absorption capacity compared with the reinforced concrete structures.

Concrete filled steel tubular column comprising a hollow steel tube infilled with concrete has been used widely in high rise buildings.
