摘要
在混凝土结构构件中,与混凝土协同工作、提高其承载能力的筋材统称为增强筋。通过对增强筋与混凝土黏结的宏观、微观分析,建立了增强筋与混凝土黏结的本构关系模型。同时基于理论研究和有限元分析,得到增强筋与混凝土黏结-滑移关系及黏结应力分布。研究结果表明,理论分析与试验结果吻合较好。
It is collectively referred to as reinforcing bar which is able to be in the cooperative work with concrete , and improve the bearing capacity of concrete structure and component .It was obtained the theoretical calculation methods of bond-slip constitutive relation through macro and microscopic analysis of reinforcing bar and concrete , and bond stress distribution and macro bond-slip constitutive relation through theoretical and finite element analysis . Finally, it was contrasted the data of theoretical calculation and experiment , and found that the results of the experiment were consistent well with those of the theoretical analysis .
