中文摘要：
对4根配置HRB500钢筋的混凝土桥墩抗震性能进行了拟静力试验的研究，对其在低周往复荷栽作用下的破坏特征、滞回曲线、骨架曲线、刚度退化进行分析，研究钢筋强度、箍筋间距、轴压比对桥墩抗震性能的影响规律．结果表明，增大钢筋强度对提高构件的承载能力和变形能力效果显著，配箍率对构件承载能力和变形能力的影响不大，轴压比的增大虽可以显著提高构件承载能力但却不能提高构件的变形能力．
英文摘要：
Based on the quasi-static test study of seismic performance of HRBS00 reinforced concrete piers , influence law about steel strength, the spacing, the axial compression ratio on seismic behavior was obtained according to the analysis of its failure characteristics, hysteresis curves, skeleton curves, stiffness degradation under low cyclic loads. The results show that increasing steel strength can improve components＇ bearing ca- pacity and deformation capacity obviously,stirrup ratio can not influence members＇ bearing capacity and de- formation capacity, axial compression ratio can improve components＇ bearing capacity, but on the other hand, it is useless to improve components＇ deformation capacity.
