“…Other than deformation, failure is also because of spalling effect during heating process, where it is believed to be caused by the buildup of pore pressure called "moisture clog" as shown in Figure 6 ( Han et al, 2003b;Liu et al, 2014). Hence, confinement effect on the concrete in-filled by the steel prevents spalling that might occur in the RC under lateral loading such as earthquake (Bagherinejad et al, 2015).…”

Purpose Concrete-filled steel hollow (CFHS) column is an innovation to improve the performance of concrete or steel column. It is believed to have high compressive strength, good plasticity and is excellent for seismic and fire performance as compared to hollow steel column without a filler. Design/methodology/approach Experimental and numerical investigation has been carried out to study the performance of CFHS having different concrete in-fill and shape of steel tube. Findings In this paper, an extensive review of experiment performed on CFHS columns at elevated temperature is presented in different types of concrete as filling material. There are three different types of concrete filling used by the researchers, such as normal concrete (NC), reinforced concrete and pozzolanic-fly ash concrete (FC). A number of studies have conducted experimental investigation on the performance of NC casted using recycled aggregate at elevated temperature. The research gap and the recommendations are also proposed. This review will provide basic information on an innovation on steel column by application of in-filled materials. Research limitations/implications Design guideline is not considered in this paper. Practical implications Fire resistance is an important issue in the structural fire design. This can be a guideline to define the performance of the CFHS with different type of concrete filler at various exposures. Social implications Utilization of waste fly ash reduces usage of conventional cement (ordinary Portland cement) in concrete production and enhances its performance at elevated temperature. The new innovation in CFHS columns with FC can reduce the cost of concrete production and at the same time mitigate the environmental issue caused by waste material by minimizing the disposal area. Originality/value Review on the different types of concrete filler in the CFHS column. The research gap and the recommendations are also proposed.

Concrete-filled hollow sections (CFHSs) with foam concrete (FC) are a lightweight material used to reduce structural members' deadweight. Research on applying FC filled into steel hollow sections (SHSs) is still ongoing. The ultimate and compressive strengths of FC-filled SHSs are unsatisfactory, and buckling occurs on the tops or bottoms of their specimens. Therefore, this study aimed to improve the strength and reduce the buckling of CFHSs by using FC added with steel fibre (SF) and rice husk ash (RHA). Rectangular SHS columns with the cross-section dimensions of 100 mm × 100 mm × 2000 mm and 2 and 4 mm thicknesses were tested under static load to determine their strength. The cube test was conducted to determine the compressive strength of the modified FC. Results showed that CFHSs filled with RHA-and SFmodified FC had higher strength than CFHSs filled with RHA-modified FC. Therefore, using modified FC as concrete material in CFHSs is acceptable.

“…They validated their model by comparing the simulation results with the data of some experimental tests. Bagherinejad et al (2015) numerically studied the effect of eccentric loading on the buckling behaviour of rectangular CFST columns using ABAQUS software. Zhao et al (2018) used experimental and numerical analyses to investigate the behavior of large-scale circular CFST columns under axial compression.…”

As a result of the excellent performance under different loading conditions, concrete-filled steel tubular (CFST) stub columns are extensively used recently. The current study employs a 3D finite element analysis to assess the response of (CFST) stub columns when subjected to axial compression. The effect of some parameters of concrete and the confining steel tube where numerically investigated. The steel was considered as an elastic perfectly plastic material, whereas a damage plasticity behaviour was adopted for the concrete material. Analysis results suggested that the ultimate strength of concrete increases with the increase of its grade. On the other hand, increasing magnitudes of concrete grade caused a reduction in the ductility of the composite columns. Also, the increase in the steel yields stress, and the steel tube wall thickness contributes to an increase in the columns’ ultimate strength. However, they reduce the action of the concrete grade that increases the column’s ultimate strength. It was also noted that the ductility that the circular CFST stub columns showed is larger than that for square columns. Thus, the use of square CFST columns with high strength concrete, especially in seismically active areas, should be carefully considered.
