钢筋混凝土是由钢筋和混凝土两种具有不同物理力学性质的材料组合而成的复合材料,其本构模型比较复杂.钢筋与混凝土两者之间的粘结滑移关系,虽然历经近百年的试验研究,对钢筋混凝土机理的认识水平日益深刻,但在有限元分析中还不是很完善.通过选用合适的材料本构模型和粘结滑移模型,建立有限元分析模型,从而进行全过程的模拟分析.%RC is a composite material with rebar and concrete that have different physical mechanics characters, and its constitutive relationship is relatively complex. Although through experimental study in almost a century,it is increasingly understanded in cognition about mechanism of RC,the bond-slip relationship between rebar and concrete has not been deeply studied in finite element analysis. In this paper, through selecting proper material constitutive relationship and bond梥lip model.finite element analysis model is established,and simulate analysis in all process is completed.
