| 摘 要： | 分析了钢筋混凝土粘结力的机理及组成,根据带肋钢筋与混凝土之间的作用,推导了开裂前粘结力的本构关系方程式,结果表明开裂之前粘结力大小与混凝土的泊松比关系不大,主要由肋间的滑移面角度和混凝土的弹性模量决定。

| Abstract: | This paper analyzed the mechanism and composition of adhesive force of reinforced concrete, according to role of ribbed steel bars and concrete, deduced the constitutive relationship equation before cracking of adhesive force, the results showed that the relationship before cracking of adhesive force was poor with the poisson ratio of concrete, mainly determined by the slip surface angle of rib and the elastic modulus of concrete. |
