In order to develop a method for analyzing shear behavior in reinforced concrete, this study derives a constitutive equation for stress transfer upon cracked surfaces in light-weight and normal-weight concrete. The complex asperity of cracked surfaces is quantitatively determined by gathering high-precision data. The geometrical characteristics of cracked surfaces can be represented as the product of the contact angle probability density and the effective ratio of contact roughness, described in a previous paper by the same authors. In this paper, the authors discuss the relationship between contact compressive stress and strain in a direction perpendicular to the contact surface, proposing a constitutive equation for stress transfer upon cracked surfaces. The proposed constitutive equation can be used to predict a series of stress transfers upon cracked surfaces in light-weight and normal-weight concrete.
