摘　　要：对 12个方形截面钢管混凝土 (以下简称为方钢管混凝土 )轴向压缩的荷载 -变形关系进行了试验研究 ,考察了不同套箍系数下方钢管混凝土的延性指标 ,证明了钢管对核心混凝土约束的有效性。Based on the relationship between load of axle pressure and distortion of 12 square steel tubes concrete, the ductility index of square steel tubes concrete was studied under different casing hoop steel coefficients. It proves that tubes are effective on the restriction to concrete.
