STUDY OF CONSTITUTIVE RELATION AND DISTRIBUTION BETWEEN REINFORCING BAR AND CONCRETE
-
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。Abstract: 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.
