[提要]  碳纖維布加固混凝土梁的破壞形態(tài)中，剝離破壞是一種與普通混凝土梁破壞形態(tài)完全不同的脆性破
壞形式，也是設(shè)計(jì)控制狀態(tài)之一。根據(jù)試驗(yàn)研究，對(duì)受彎加固碳纖維布的剝離全過(guò)程進(jìn)行了分析，通過(guò)與有限元計(jì)算結(jié)果的比較，建立了剝離過(guò)程的分析模型，為理論分析奠定了基礎(chǔ)。

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
