| 摘 要： | 通过3根芳纶纤维布加固钢筋混凝土梁和1根基准混凝土梁的抗弯性能试验,研究了芳纶纤维布层数对加固混凝土梁的抗弯承载力、刚度和破坏特征的影响.试验结果表明,粘贴芳纶纤维布可以有效地提高被加固梁的抗弯承载力.根据不同的破坏模式,给出了芳纶纤维布加固钢筋混凝土梁的抗弯承载力计算公式,计算结果与实测结果符合良好. |
| 关 键 词： | 芳纶纤维布 钢筋混凝土梁 加固 抗弯承载力 |

| Abstract: | Three reinforced concrete (RC) beams with externally bonded aramid fiber reinforced plastics (AFRP) sheets and one RC beam are experimentally investigated.A study is given to the effect of AFRP sheet on flexural capacity,stiffness and failure mode of the beam.The results generally indicate that the flexural strength of the strengthened beams is increased.At the same time,an analytical solution is proposed to testify the experimental results.The analytical results agree well with the experimental results. |
| Keywords: | AFRP sheet RC beam Strengthening Flexural capacity |
