摘要

通过对3根分别配置高强钢筋和普通钢筋的混凝土墩柱进行的拟静力荷载试验,详细测试和观察、分析研究了其抗震性能.详细记录和描述了结构的破坏特征和破坏形式,研究了其滞回曲线、骨架曲线的特征,分析了钢筋强度、混凝土强度、箍筋间距等因素对桥墩延性的影响.
Two groups of concrete circular piers are tested in this paper: one,embedded with high-strength steel bars,and the other,with ordinary steel bars.All are put under quasi-static test.The results are carefully recorded,and their respective anti-seismic properties analysed.In the observation,the characteristics of damages are recorded.The features of the hysteresis curves and the skeleton curves are studied.The influence of the strength of steel bars,that of concrete and the arrangement of the bars on the ductility of piers is analysed.
