摘要
通过改变粘贴碳纤维布的层数、粘贴方式,进行了4根碳纤维布增强钢筋混凝土梁的疲劳试验和2根普通钢筋混凝土梁的疲劳对比试验研究,试验结果表明,碳纤维加固可以较大的提高混凝土梁的疲劳性能,延长混凝土梁的使用寿命;粘贴碳纤维布的方式以及粘贴层数对钢筋混凝土梁的抗疲劳性能有很大的影响.
According to the change of layers and the way of gluing of CFRP, the fatigue performance of four RC beams strengthened with CFRP have been compared with two RC beams by fatigue experiment. It is shown that the fatigue performance is greatly improved and the fatigue life is prolonged. The layers and the way of gluing of CFRP have great effect on fatigue performance of reinforced concrete beams.
