| 摘 要： | 为了研究碳纤维增强复合材料（CFRP）修复震后玻璃纤维增强复合材料（GFRP）管混凝土桥墩柱的抗震性能,对4根CFRP修复震后破坏GFRP管混凝土桥墩柱进行拟静力试验,对比修复后钢筋混凝土桥墩柱与原型桥墩柱的滞回曲线、骨架曲线、延性和耗能能力。试验结果表明,修复后的墩柱承载力和延性指标均能得到较好的恢复甚至提高。

| Abstract: | In order to investigate the seismic behavior of earthquake-damaged GFRP(Glass Fiber Reinforced Polymer) tubed reinforced concrete bridge piers repaired with wrapped CFRP(carbon fiber reinforced polymer or plastics) sheets,four GFRP tubed RC bridge piers repaired with wrapped CFRP sheets were tested under repeat low cyclic load.The hysteresis loops,skeleton curves,ductility and energy dissipation ability of the repaired RC bridge piers were compared with those of the original piers.Research show that the bea... |
