| 摘 要： | 通过８根轴压、６根小偏压箍筋约束高强砼短柱的试验，研究了箍筋约束作用对单轴受压时应力－－应变关系及相关参数的影响。分析了箍筋形式、配箍率等参数对柱延性的作用，并对小偏压柱强度和变形性能进行了探索。在试验研究的基础上，提出了约束高强砼的应力－应变关系全曲线及相关参数的计算表达式。

| Abstract: | Based on the test of high strength concrete (HSC)short columns confined with stirrups 8 under axial loads and 6 under small eccentric loads, the influence of stirrups confinement on stressstrain relationship and related parameter under monoaxial compression are studied, and the effect of the type of stirrups, stirrup ratio, etc. on the HSC columns ductility is analysed. Besides, the strength and deformation behavior of HCS columns under small eccentric compression are explored.Based on the experimental study, the complete stress-strain curves of confined HSC and the formula for calculating the related parameter are presented in this paper. |
