Mechanical Behaviour of Cold-Formed Steel Column with Infill: A Review

Abstract

Composite steel-concrete construction utilising the benefits of both materials has extensively been used in
structural engineering. Concrete-filled tube columns can provide excellent seismic resistant structural properties such
as high strength, high ductility, and large energy absorption capacity. In addition to the enhancement in structural
properties, a considerable amount of construction time can be reduced due to the prevention of permanent formwork.
In this type of column, the steel tube can support considerable amounts of loads while providing permanent formwork
to the concrete. Likewise, the steel tubes add confinement to the concrete whereas the concrete infill delays the local
buckling of the steel tubes. In recent years, stainless steel tube members have become popular due to the high
corrosion resistance, ease of construction and maintenance as well as aesthetic appearance. Concrete-filled hollow
steel sections are more and more frequently used as compression members in structures nowadays. This paper
investigates the mechanical behaviour such as Buckling behaviour, Load carrying capacity and Seismic resistant of
cold formed steel column with infill.
