En estos elementos, el daño se modela como el desarrollo de rótulas, dislocaciones transversales y discontinuidades axiales. Estos elementos finitos utilizan modelos constitutivos para considerar la capacidad de momento, fuerza cortante y fuerza axial, basados en la mecánica del daño y en pruebas experimentales reportadas en la literatura, las cuales incluyen el comportamiento constitutivo del concreto con acero de refuerzo. Para mostrar la capacidad de modelar el daño de los elementos finitos desarrollados, se presentan ejemplos numéricos de vigas y marcos de concreto reforzados sujetos a cargas que inducen daño. En estos ejemplos numéricos, las curvas de la carga contra el desplazamiento calculadas son congruentes con las reportadas en la literatura.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract: Frame elements with embedded discontinuities to model the development of hinges are formulated. In these elements, damage is modelled as the development of hinges, transversal dislocations and axial discontinuities. These elements use constitutive models to include the capacity of the moment, shear force and axial force, based on the damage mechanics and experimental tests reported in the literature, which include the constitutive behaviour of concrete with steel reinforcement bars. To show the ability of the formulated finite elements with embedded discontinuities for modelling damage, numerical examples of reinforced concrete structural beams and frames under loads, which induce damage. In these numerical examples, the load-displacement curves are in agreement with those reported in the literature.]]></p></abstract>
