| Abstract: | Eight concrete-filled thin-walled steel tube columns are made and the properties of concrete-filled thin-walled steel tube columns under axial compression are studied in this paper.The factors including D/t ratio,L/D ratio and annular hoop bar are discussed.The phenomenon of experiment and the form of collapse of the specimens are described,then the ultimate capacity and the strain of tubular are analysed in detail.The core concrete is confined strongly by thin-walled steel tube.Confining degree is affected... |
