摘　　要：进行了8个试件的滞回性能试验研究,其中包括2个钢筋混凝土超短柱、2个型钢混凝土超短柱、2个钢筋混凝土分体柱和2个型钢混凝土分体柱;超短柱的剪跨比都为1,而分体柱的剪跨比都为3.试验结果表明,型钢混凝土超短柱的破坏模式为粘结破坏,因此与钢筋超短柱相比,构件的承载力、延性和变形能力并无显著提高.与超短柱相比,钢筋混凝土与型钢混凝土分体柱的延性和变形能力明显提高.随轴压比的提高,钢筋混凝土与型钢混凝土分体柱的延性与变形能力降低.相同轴力水平下,型钢混凝土分体柱的承载力、延性和变形能力明显优于钢筋混凝土分体柱.The hysteretic behavior of 8 specimens including 2 reinforced concrete(RC) ultra short columns,2 steel reinforced concrete(SRC) ultra short columns,2 separated RC columns and 2 separated SRC columns have been studied.The shear span to depth ratios of ultra short columns and separated columns are 1 and 3 respectively.The test results show that the failure mode of SRC ultra short columns is bond failure;and the shear strength,ductility and deformation ability of SRC ultra short columns are not evidently highe...
