摘要
在损伤力学理论基础上,对FRP—混凝土界面剥离破坏进行损伤分析,基于现有的粘结滑移本构模型,建立界面损伤滑移模型,获得了不同粘结滑移本构关系的损伤滑移曲线,同时利用所得损伤滑移曲线,建立有限元分析模型,分析了粘结面剥离损伤破坏特征,验证了损伤滑移本构关系的正确性和可用性。
Based on damage mechanics, the mechanism of cover delamination was studied. Used the existing bond-slip constitutive models, the damage-slip constitutive models are presented. Finally, used the damage-slip curves, finite element models were founded to analyse the damage mechanism of the interface debonding between FRP sheet and concrete. Correctness and usability of the the damageslip constitutive models is validated.
