The use of concrete filled steel tube (CFST) columns offers an alternative for
providing the required fire resistance and load bearing capacity, making its use
in medium and high rise structures are highly popular. This paper aims to review
the previous studies on CFST column under fire. The standards or codes of
practice used in fire resistance designs have been highlighted. The design of the
CFST column is summarised with previous investigations on experiments and
numerical modelling at ambient temperature and elevated temperature.
Different conclusions were drawn depending on the material’s properties,
considered parameters and the method used for the investigations. Outer
diameter or width of the steel tube, steel tube thickness, concrete grade,
column length, and eccentricity of loadings are among the parameters that
affects the structural behaviour of CFST columns under fire. Several numerical
analyses software were adequately used for simulating the behaviour of CFST
columns at elevated temperatures, and validated using experimental results.
Furthermore, the advantages of using the fire resistance design approaches on
CFST columns filled with lightweight foamed concrete is highlighted. In
conclusion, there is the need for more studies on standard fire tests of CFST
column filled with light weight foamed concrete which is not covered in the
current design guide.
