碳纤维布加固混凝土受弯构件的剥离破坏及其防治

DEBONDED FAILURE OF RC FLEXURAL MEMBERS STRENGTHENED WITH CARBON FIBER SHEETS(CFSS)AND ITS PREVENTION

对碳纤维布加固混凝土受弯构件破坏形态中的剥离破坏现象进行了介绍 ,并对抗弯加固时纵向碳纤维布剥离区域的状态和破坏过程进行了力学描述 ,归纳出影响碳纤维布剥离的主要因素。最后提出了防治剥离破坏现象的工程处理建议。

The phenomenon about debonded failure of RC flexural members strengthened with carbon fiber sheets(CFSs)has been introduced in this paper.The states and process of CFSs debonded area in flexure RC beams also has been described by mechanical analysis.The main factors influencing debonded failure of CFSs have been concluded.Finally,engineering measurements to prevent debonded failure have been advised.
