【摘要】 为了对CFRP-混凝土之间的界面力学行为及界面剥离破坏机理问题进行进一步认识,在大量试验结果的基础上,进行有限元模拟,分析了影响界面力学性能的有关参数和影响界面剥离性能的主要因素,对剥离破坏模式和机理进行了详细的分析。对裂缝的开展过程进行了仔细观察,并分析其开展机理,分析了CFRP加固混凝土的界面的黏结应力,从理论上得出CFRP对混凝土梁的加固效果十分显著,大大提高试验梁的承载力。更多还原

【Abstract】 For further understanding interface mechanical behavior and peeling failure problem between CFRP and concrete,based on a lot of experiment and finite element simulation,some related parameters of which will affect interface mechanical properties and some related actors of which will affect interface peeling property are analyzed.Through analyzing peeling failure model and mechanism.The launching process of the cracks,and analysis of its mechanism and CFRP reinforced concrete interface bond stress are expounded.Derived from the theory of CFRP,reinforced concrete beams achieved significantly reinforcing performance and enhance the bearing capacity of the test beam.更多还原
