| 摘 要： | 玄武岩纤维由于其良好的力学性能、较好的稳定性和较低的价格使其在土木工程中的应用前景广阔,但目前玄武岩纤维在土木工程中应用的相关研究还极少。通过对连续玄武岩纤维丝束缠绕与碳纤维布加固混凝土圆形柱抗震性能的对比试验,对FRP种类和用量对加固效果的影响进行了研究。研究结果表明,这两种纤维加固都可以有效地提高混凝土圆柱的抗震性能,而玄武岩纤维性价比更好。 |

| Abstract: | Basalt fiber is expected to be widely applied in civil engineering for its fine mechanic performance,good stability and comparatively low price.However,there is still little research in the aspect concerning with the application of basalt fiber in civil Engineering.Comparative test on the seismic performance of circular concrete column strengthened with basalt fiber reinforced polymer(BFRP) and carbon fiber reinforced polymer(CFRP) was conducted.The influence of fiber type and fiber amount on the strengthening effect was discussed.Test results show that BFRP and CFRP can both obviously improve the seismic performance of circular concrete columns,and more,BFRP has higher ratio of performance to price. |
| Keywords: | circular concrete columns continuous basalt fiber seismic retrofit ductility |
