Compressive resistance of short concrete-filled double-skin columns with outside steel and inside PVC circular tubes

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review

Abstract

An experimental study was conducted on twelve (12) concrete-filled double-skin circular tubes (CFDSCTs) with external steel tubes and internal PVC tubes. Two sizes of steel tubes (152.4 x 3mm and 165.1 x 3mm) were chosen, and the inner PVC tubes of 40mm and 50mm diameter tubes were selected to allow the concrete to move freely during compaction. Six (6) concrete-filled circular tubes (CFCTs) were also cast to establish the influence of the PVC pipes. The column heights were limited to three times the outer diameter to prevent overall buckling mode failure and promote local buckling of the steel tube and crushing of the concrete. Both the outer steel and inner PVC tubes failed by local buckling. The test results indicate that all the columns acted compositely until failure.
