Two-dimensional modeling of material failure in reinforced concrete by means of a continuum strong discontinuity approach

Abstract: The paper presents a new methodology to model material failure, in twodimensional reinforced concrete members, using the Continuum Strong Discontinuity Approach (CSDA). The Hill's mixture theory is used as the methodological approach to model reinforced concrete as a composite material, constituted by a plain concrete matrix reinforced with two embedded orthogonal long fiber bundles (rebars). Matrix failure is modeled on the basis of a continuum damage model, equipped with strain softening, whereas the rebars … Show more

“…The strategy presents herein is based on a modification of the steel constitutive behavior and on the slipping-fiber model proposed by Oliver et al (2008). This model condenses in an single constitutive relation both reinforcement and bond to concrete constitutive laws.…”

These enrichments are based on general known behavior of fiber-matrix connections.…”

“…In the 2D longitudinal model, reinforced concrete was modeled as a composite material (Figure 7), as proposed by Oliver et al (2008), constituted by a matrix, representing concrete, with embedded fibers representing reinforcement. The ICDM, together with the CSDA and upgraded with the initial damage obtained from the cross section analysis, was used in order to model de deteriorated matrix behavior.…”
