摘    要:通过9根剪跨比λ=2.0的试件。对C80型钢高强混凝土柱在低周反复荷载作用下的抗震性能进行了试验研究.试验主要考虑配箍率和轴压比两个参数对构件延性的影响.根据试验结果,得出了配箍率和轴压比与构件位移延性的关系曲线.在满足一定位移延性的基础上.提出了C80型钢高强混凝土柱的轴压比限值;并就配箍率对轴压比限值的影响进行了分析。进一步提出了与不同配箍率相关的轴压比限值.

关 键 词:C80型钢高强混凝土    延性  轴压比限值

Abstract:Nine steel reinforced high-strength concrete (SRHC) columns with the span ratio of 2.0 are constructed and tested under a simulated earthquake loading. The grade of concrete strength is C80. The two factors, i.e., the stirrup ratio and axial compression ratio, affecting the ductility of SRHC columns, are taken into consideration. The interrelated curves between ductility and those factors are obtained from test results. By muting certain requirements of ductility, the limit values of axial compression ratio of C80 SRHC columns are put out, and the influence of stirrup ratio on it is also analyzed.
Keywords:C80 steel reinforced high-strength concrete  columns  ductility  the limit values of axial compression ratio
