STEEL-CONCRETE BOND ANALYSIS WITH NONLOCAL CONTINUOUS DAMAGE

A method of analysis of the response of reinforced concrete elements is proposed that is based on 2 assumptions: there is no discontinuity of displacements at the steel-concrete interface; and the isotropic (scalar) damage model is acurate enough to model the response of concrete under shear stresses. A simple modification dealing with the combination damage due to tensile stresses and damage due to compressive stresses is proposed. The paper describes how the implementation of the nonlocal damage model in the analysis of reinforced concrete elements must combine local and nonlocal constitutive relations. It was found that the size and shape of the damage zone are consistent with experiments and with previous calculations with smeared or discrete crack models.
