“…Lu et al [13] study the effect of polypropylene-steel fiber on the axial loading behavior of CFST, the result shown that the hybrid fiber has negligible effect on the ultimate capacity and failure mode. The structural performance of concrete-filled FRP tube with a hybrid steel/glass fiber reinforced tube was investigated by Hain et al [14], they found the hybrid concrete-filled FRP tube specimens exhibited lower degradations in stiffness and higher energy absorption .…”

There have been great developments in the area of civil engineering in the recent few decades and among these, construction and material innovation are quite prominent. Steel-concrete composite construction has emerged as one of the fastest methods of construction. Even though considerable research efforts on conventional reinforced concrete columns have been executed prior to now, concrete filled steel tube (CFST) composite columns however have received limited attention. This work aims to study the experimental behavior of steel tubular specimens. Plastic and steel specimens are considered with circular and square sections filled with the concrete with the steel fiber and as well, plain concrete. Four parameters are considered in this study which are sectional designs (circular and square), tube thickness (2 and 5 mm), tube material (plastic and steel) and content of steel fiber (0 and 5%). Ten concrete filled steel tubular columns were cast and tested. Two circular columns were made from plastic and the other made from steel. The main purpose of this work are study the effect of steel fiber and cross section on the ultimate load capacity of columns. It was discovered the utilization of steel fiber reinforced concrete filled steel tubular columns have comparatively substantial stiffness in comparison with plain concrete filled columns.
