EXPERIMENTAL RESEARCH ON THE BEARING BEHAVIOR OF HIGH-STRENGTH-CONCRETE-FILLED STEEL TUBE UNDER AXIAL COMPRESSION

摘要: 本文报导了21个钢管混凝土轴压短柱的试验研究,其中18个钢管高强混凝土试件,3个普通钢管混凝土试件。试验的主要参数是套箍系数ξ。研究结果表明,当套箍系数较小时,钢管径向变形对钢管高强混凝土极限承载力有影响。

Abstract: The experimental research performed on twenty-one specimens of short steel tubular columns filled with concrete under axial compression is reported. Eighteen specimens of steel tube are filled with high-strength concrete and three specimens are normal concrete-filled steel tubes. The main parameter of specimens is confinement coefficient. Research result shows that the radial deformation of steel tube has influence on the ultimate bearing capacity of steel tube filled with high-strength concrete, when the confinement coefficient is small.
