钢筋与混凝土粘接性能的研究进展

Bond strength between reinforcing steel bar and concrete

钢筋混凝土结构由于其结合了钢筋与混凝土的优点，是结构设计中的首选形式，应用非常广泛。钢筋与混凝土之间的粘结滑移性能是许多学者一直致力于研究的热点课题，然而由于钢筋与混凝土临界面传力机理复杂、影响因素众多、试验手段的不同和量测技术的差异等导致了试验数据的分散，因此，至今尚未得出比较一致的结论。本文主要从粘结试验方法、粘结滑移本构关系、有限元分析等方面对国内外研究现状进行简述。

Reinforced concrete structure is often selected firstly and has a common application. Many researchers have been devoting themselves to the study of the bond strength between reinforcing steel bar and concrete. However, because of the complexity of the transferring-force on the interface between them, a number of factors and different tests and diverse surveys have led to sporadic experimental data, we don＇t have any uniform conclusion up to now. External and internal research status of this experiment, the bond-slip relationship and FEM analysis are discussed briefly.
