Abstract
An anisotropic elasto-damage model for predicting the response of concrete subjected to
monotonic and fatigue loading is presented in this research. The model utilizes a concrete appropriate
damage-effect tensor M in constructing the constitutive equations using the concept of multiple bounding
surfaces. One of the salient features is the introduction of a bounding surface that constrains the elliptical
movement of the limit fracture surface. The model after calibration is shown to predict the monotonic,
comprehensive uniaxial stress strain path for concrete of various strengths as well as S-N curves depicting
the fatigue response of concrete for uniaxial and biaxial loading. A concept of residual strength
determination based on continuum damage formulation is also introduced.
