就部分粘贴CFRP加固钢筋混凝土梁正截面抗弯性能及结构破坏模式进行了试验研究。介绍了部分粘贴CFRP加固钢筋混凝土梁正截面试验方法,探讨了部分粘贴CFRP下无粘结长度对结构破坏形式、结构抗弯性能、受拉主筋受力性能及CFRP受力性能的影响。结果表明采用部分粘贴CFRP加固钢筋混凝土梁正截面的方法能有效地提高结构抗弯性能和改变结构的破坏模式,具有较好的推广和应用价值。

In this paper, the experiments on right sectional bending resistance nature and structural damage pattern of the RC beams strengthened by bonding CFRP partially are studied. The the experiment methods on right section of RC beams strengthened by bonding CFRP partially are introduced, and the non-cohensive length of CFRP effect on structural damage pattern, bending resistance nature and weighted performance of tention reinforcement and CFRP are discussed. The results demonstrate that the way of using bonding CFRP partially to strengthen right section of RC beams can effectively increase structural bending resistance nature and improve structural damage pattern which has good value of popularization and application.
