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。 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.
