摘　　要：通过 3根高轴压比高强混凝土短柱在低周反复荷载作用下的抗震性能试验研究 ,分析和讨论了高强混凝土框架短柱的裂缝开展过程及分布、钢筋的应变变化规律、箍筋形式及配箍率对高强混凝土框架短柱变形的影响。Based on the seismic behavior experimental research on 3 high-strength concrete short columns under low-frequency cyclic loading,it is discussed and analyzed that the developing process and distributing of cracks at high-strength concrete short columns crack,reinforcing steel bar′s strain′s variational regular pattern and the influence of type of stirrups and stirrup ratio on modification of high-strength concrete short columns.
