摘要
纤维复合材料(FRP)以其轻质、高强、抗腐蚀能力强、耐疲劳、减震性能好等诸多优点被广泛运用到土木、建筑工程结构加固中。结合国内外复合材料加固混凝土技术的进展,论述了约束混凝土的本构模型,加固混凝土结构的极限承载力、耐久性、抗震性以及纤维复合材料加固混凝土结构的机理等。并且阐述了纤维复合材料加固混凝土柱的机理。最后,论述了一种新的可用于碳纤维加固混凝土结构的粘结材料—聚脲弹性涂层,可以有效改善混凝土柱构件的承载能力、耐久性及抗震性能等。
Fiber composite polymer has been widely used to structure reinforcement of civil engineering and architecture because of its light weight,high strength,corrosion resistance,fatigue resistance,damping performance etc. Based on the research progress of composites reinforced concrete technology,this paper discussed the constitutive model of reinforced concrete and the ultimate bearing capacity,the durability,the earthquake resistance of the reinforced concrete structure and the mechanism of fiber composites reinforced concrete structure. Finally polyurea elastomeric coating as a new reinforcement material was introduced in this paper,which can effectively improve the bearing capacity,the durability and the earchquake resistance of the reinforced concrete structure.
