[提要]  碳纤维布加固混凝土梁的破坏形态中,剥离破坏是一种与普通混凝土梁破坏形态完全不同的脆性破
坏形式,也是设计控制状态之一。根据试验研究,对受弯加固碳纤维布的剥离全过程进行了分析,通过与有限元计算结果的比较,建立了剥离过程的分析模型,为理论分析奠定了基础。

Debond of carbon fiber reinforced polymer( CFRP) sheets is a special failure mode of RC beams strengthened with CFRP sheets,which is a kind of design control state. This mode is a brittle failure mode different from failure modes of usual RC beams. Based on experimental study, the debond process of CFRP has been depicted in detail. An analytical model of debond process has been put forward by comparing with calculating result of finite element method.
Keywords: carbon fiber sheets; concrete beams; debond breakage; finite element method; process analysis
