摘要
通过１５根Ｃ８０高强混凝土柱在低周反复荷载作用下受力性能的试验研究，分析了混凝土强度、轴压比、配箍率、箍筋强度、纵向钢筋配筋率等因素对构件延性的影响．在满足构件有限延性（μΔ≥３）的基础上提出了Ｃ８０高强混凝土柱在不同抗震等级下轴压比的限值和柱加密区箍筋最小体积配箍率的建议值，可供设计参考．
Based on the experimental research of 15 columns using C80 high strength concrete under low frequency cyclic loading, the factors which affect the ductility, such as the concrete strength, axial load ratio, stirrup volume ratio, stirrup strength, longitudinal steel ratio, etc., are analyzed. The axial load ratio limits and relative minimum stirrup volume ratio in the region of closely spaced stirrups in column are proposed under the condition of limited ductility (μ Δ≥3) for difference grade of aseismatic design.
