摘要
选择不同的碳纤维板板宽、数量、有无锚固措施及不同的锚固方式等作为试验参数,对9根采用碳纤维板加固的钢筋混凝土梁进行了抗弯性能研究。试验结果表明:这些加固措施有效地提高了梁的抗弯极限承载力和刚度,较好地约束裂缝的发展,具有良好的加固效果。有良好锚固措施时,其抗弯承载力显著提高。
In this paper, the experiment selected carbon fiber-reinforced plates sheets＇ different width, amounts, anchoring or not and different anchoring methods as parameters. 9 RC beams strength- ened with carbon fiber-reinforced plate sheets were tested to investigate the flexural behavior. The exper- imental results showed that the flexural load-carrying capacity and stiffness were increased effectively and the propagation of cracks was reduced obviously by the rehabilitation. Flexural load-carrying capacity of RC beams with CFRP sheets end anchorage has been strengthened remarkably.
