| 摘 要： | 嵌入式(NSM)加固法是FRP材料加固混凝土结构的一种新的应用形式。通过CFRP板条嵌入混凝土试块的界面单剪试验,研究粘结长度对界面粘结性能的影响。根据实测应变分布,得到沿粘结长度界面粘结应力分布,并通过计算分析,对局部粘结滑移关系进行了初步探讨。

| Abstract: | Near -surface mounted(NSM) FRP reinforcement is emerging as a promising technique for the strengthening of concrete structures.It is presented an experimental study on the bond behavior of NSM CFRP strips using a simple shear test set -up.The effect of bond length on bond performance is examined.The failure mode,the FRP strain and bond stress distributions,and the local bond -slip relationship are all discussed. |

| Keywords: | CFRP near-surface mounted concrete bond |
