Abstract

This research studies the behavior of double tube steel columns filled with high-strength concrete (HSC) between the gap surrounded by the two pipes and others without filling. The columns are tested by using a concentrated centric load. The concentrated load was applied in the form of cycles by the increased load. Six samples of columns were examined with different variables. The study’s parameters in the experimental work are specific to the steel fiber in the concrete mix and type section and the other parameter to the non-filled tube. In terms of high strength concrete mix, the percentage of fibers used was 0.5% and 1.5% of the total concrete volume. As for the steel tube, a square and circular cross-section was used, as well as column length. Plotting the results obtained through load curves with deflection and the results were compared with samples non filled with concrete. The results showed that increasing the percentage of fibers in high strength concrete increases the maximum bearing of the column, while an empty tube has much less bearing than it is infilled with high strength concrete. Finally, the theoretical analysis of the results was performed with ACI. From the experimental results, the ACI provision gives underestimation about the load carrying capacity of the composite column and overestimation for only steel.
