摘　　要：通过对3根T形截面钢骨混凝土短柱和1根T形截面钢筋混凝土短柱在承受不同轴压比下的水平周期性荷载试验的研究,发现在T形截面钢筋混凝土短柱中加入适量的钢骨,对构件的延性有很大提高;另外轴压比对构件的延性有很大影响,轴压比高构件延性差,轴压比小构件延性好。Based on the experimental studies for two kinds of specimens, i.e. , three T-shaped steel reinforced concrete short columns and one T-shaped common reinforced concrete short column under horizontal cycle loadings, we can conclude that the addition of steel in these columns will increase their ductility apparently. In addition, it can be also concluded that different axial compression ratio has different effect on the ductility of the columns, i.e., the ductility corresponding to the lower axial compression ratio is always better than that corresponding to the higher axial compression ratio, and vise vase.
