摘要
纤维增强聚合物塑料(FRP)因其具有抗腐蚀、抗疲劳、强度高、质量轻等优点在工程中得到广泛应用,但是FRP加固混凝土梁常因界面剥离而发生破坏,因此FRP与混凝土两者之间的粘结性能是影响FRP与加固混凝土梁之间能否共同工作的重要因素。针对剥离破坏问题,本文从试验研究以及有限元分析法两个方面,对目前剥离试验的试验方法以及破坏形式进行了归纳,列举了国内外针对剥离破坏的试验以及对应的影响承载力的因素,并通过分析指出了在研究粘结性能领域仍存在的一些问题。
Because of corrosion resistance, fatigue resistance, high strength, light quality and non-electric magnetic advantage, fiber reinforced polymer （FRP） is widely used in engineering. Due to the interracial debonding, the breakage of FRP reinforced concrete beam often occurs, so the bonding performance between FRP and concrete is the most important factor of whether they can work together or not. From aspects of experimental studies and finite element analysis, the test method of peel test and failure form is mainly summed up, the domestic and overseas trials of the debonding failure and influencing factors of bearing capacity are cited, and some problems in the field of bond performance are pointed out.
