| 摘 要： | 通过对连续玄武岩纤维与碳纤维缠绕加固混凝土矩形柱的对比试验,指出玄武岩纤维丝束缠绕加固能够显著提高混凝土柱的抗剪承载力,转变试件的破坏形态,在相近侧向约束刚度下,连续玄武岩纤维加固柱对承载力的提高及延性、耗能等结构性能的改善都能够达到、甚至超过CFRP加固柱,而前者具有更低的价格,值得在实际工程中推广应用. |

| Abstract: | Comparative test on the seismic performance of rectangular concrete columns strengthened with basalt fiber reinforced polymer(BFRP) and carbon fiber reinforced polymer(CFRP) was conducted.Test results show that basalt fiber tow winding retrofit technology can significantly improve the shear strength of the concrete columns and change the failure modes.Contrasting to the columns wrapped with CFRP,it is confirmed that with similar lateral confinement stiffness,the strength and ductility,energy absorbing and other structural performance of the columns wounded with BFRP could be achieved,while the price of BFRP is lower.It is worthy to be widely applied to strengthen engineering structures. |
| Keywords: | continuous basalt fiber columns FRP seismic retrofit seismic behavior |
