摘　　要：通过6根组合短柱的轴心受压试验,研究钢骨-钢管混凝土组合短柱的承载能力和延性,分析影响钢骨-钢管混凝土组合短柱性能的主要因素:包括混凝土强度、套箍指标和配骨指标。研究结果表明:钢骨-钢管混凝土组合短柱具有很高的承载力和延性,可大大提高建筑物的防倒塌能力,适合在高烈度地震区的结构中应用。Through the axial compression test for six composite short columns,the bearing capacity and ductility were studied. The main factors influencing the property of steel tube-steel concrete composite short column were analyzed,including the concrete strength,confinement index and steel-reinforced index. The results showed that steel tube-steel concrete composite short column had a high bearing capacity and ductility,which could greatly improve the capacity to prevent the collapse of buildings,and suitable for application in the structures of high earthquake intensity area.
