摘　　要：通过对11根全高炉矿渣钢筋混凝土柱的低周反复荷载试验,根据各柱的滞回曲线、骨架曲线等指标,对影响全矿渣柱延性的因素进行了分析;以各柱骨架曲线为基础,得出各柱的位移延性系数,对全高炉渣柱的延性性能进行了分析。Subjected to horizontal low cyclic loading, based on the experiment of 11 columns composed by slag aggregate materials, according to indexes of hysteretic curve and skeleton curve to each column, the factors influencing ductility are analyzed. For each column, calculated yield load and limit load, displacement ductility coefficient and ductility performance are obtained.

关 键 词：全矿渣混凝土柱 低周反复荷载试验 滞回曲线 骨架曲线 轴压比 延性
