This paper represents an overview of the investigation pursued by the authors in the field of damage evaluation of concrete structures [1,2,3]. A procedure to evaluate the damage of reinforced concrete structures subjected to static and dynamic actions has been developed, which is based on a local damage constitutive model using Kachanov´s theory [4]. The constitutive model is used within a finite element frame, a non-linear Newmark-type tangent incremental time integration scheme is employed and finally, an overall global damage index, based on potential energy criteria, is developed and justified.
