| 1. | According to the geometrical characteristics of the surface on the deformed bars , considering the interfacial properties of the corrosion reinforcement and concrete , such as the microscopic mechanics model of corroded reinforcement ribs , the deterioration of ribs on the bearing surface of the deformed bars after corrosion and the effect of corrosion products of corrosion reinforced bar on the bond strength , and analyzing the distribution and interaction of the forces on the surface of the corrosion reinforcement and concrete , the calculation expressions of the bond strength between corroded deformed bars and concrete with and without transverse steel are established
从变形钢筋的表面几何特征出发,考虑了钢筋锈蚀后钢筋与混凝土接触面的特征,例如钢筋横肋在锈蚀状态下的细观力学模型,钢筋锈蚀后钢筋横肋高度的变化和锈蚀产物的生成对粘结力的影响。通过分析接触面上各种力的分布形式及相互关系,建立了有横向钢筋和无横向钢筋约束作用下,钢筋与混凝土之间粘结力的计算表达式,且与相关文献的结果进行了比较。 |
