A review on concrete-filled steel hollow column subjected to fire and cyclic loadings

Concrete-filled hollow steel column (CFHS) column is a composite column that comprised of concrete core filled into hollow steel section. The composite action between the hollow steel sections and concrete core give CFHS better performance over conventional reinforced concrete and steel column. Numbers of studies had been done on the performances of CFHS with different types of the concrete core subjected to various loadings. The concrete filling materials used by previous researchers including plain concrete, reinforced concrete, and other modified concrete such as concrete containing fly ash, recycled aggregate and rubber particles. This paper presents the performances of CFHS with different type of concrete filling materials subjected to fire and cyclic loadings. A comparison between different concrete filling materials that have been used to fill hollow steel column that were used by previous researchers are presented. Research gap and recommendations are also proposed for further study.
