Abstract

Abstract

The damage constitutive law of concrete,which can better describe the mechanical characteristics of concrete,is introduced according to the continuum damage mechanics theory. Meanwhile,the damage constitutive law of steel is established by taking account of the plastic strain development and buckling effect of steel. Based on large numbers of the experimental results of pull-out specimens on bond-slip behaviors between steel and concrete,the relationship between bond strength and the value of slip is analyzed. A coupled interfacial bond damage -s model is established and the evolution characteristic equation of bond damage is put forward?through introducing a damage variable to consider the effect of bond degeneration between steel and concrete. Numerical results of SRC beam specimens analyzed by finite element numerical simulation are compared with experimental results and calculation results obtained by existing research. The results show the bond damage -s model herein established can better reflect the effect of interfacial bond degradation between steel and concrete for structural elements,so the numerical method is effective. All these may supply theoretical basis for the nonlinear numerical analysis of SRC composite structures under earthquake.
