摘　　要：通过对3根L形钢骨异形短柱和一根L形钢筋混凝土异形短柱在承受不同轴压比下的水平周期性荷载试验的研究,发现在普通钢筋混凝土异形短柱中加入适量的钢骨,对构件延性的提高有明显作用。另外,轴压比对构件的延性有很大影响,轴压比越高构件延性越差,轴压比越低构件延性越好。Based on two kinds of specimens,i.e.,three L-shaped steel reinforced concrete short columns and one(L-shaped) common reinforced concrete short column,the ductility of them has been sufficiently studied respectively under horizontal cycle loadings,from which it is concluded 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 will become higher when the axial compression ratio becomes lower,and vice versa.the ductility corresponding to the lower axial compression ratio is always higher than that corresponding to the higher axial compression ratio,and vice versa.
