为了研究FRP加固混凝土梁的剥离问题,采用能量释放率法和J积分方法,建立分析FRP-混凝土界面损伤破坏的分析模型,并提出描述FRP-混凝土界面剥离过程的平衡路径算法.通过单向剪切试验、端部剥离试验、FRP加固梁试件3个实例验证,证明平衡路径算法及分析模型可以预测FRP-混凝土界面剥离.

In order to analyze the debonding failure of concrete beams strengthened with externally bonded fi-ber-reinforced-polymer ( FRP) plates,this paper adopts the energy-release-rate approach and the J-integralformulation,and proposes an interface damage model and an algorithm for the construction of the equilibriumpath that describes the debonding process in the FRP strengthened beam.The model and the approach of equi-librium path can be used to predict the debonding failure for the interface of FRP-concrete beam through threecases that include a single shear test,an edge peeling test,and a beam specimen strengthened with FRP.
