Axial Behavior of Concrete-Filled Double-Skin Tubular Stub Columns Incorporating PVC Pipes

Abstract: This experimental study presents concrete-filled double-skin tubular columns and demonstrates their expected advantages. These columns consist of an outer steel tube, an inner steel tube, and concrete sandwiched between two tubes. The influence of the outer-to-inner tube dimension ratio, outer tube to thickness ratio, and type of inner tube material (steel, PVC pipe) on the ultimate axial capacity of concrete-filled double-skin tubular columns is studied. It is found that the yield strength of the inner tube d… Show more

“…Combining two materials of different natures in a double-tube CFT was advantageous. This can be seen in the study by [30] that involved PVC and steel tubes. The outer PVC pipe protected the concrete and the inner tube from chemical attacks and corrosion, while the concrete and the inner tube strengthened the CFT.…”
