A plastic damage approach for confined concrete
(Pergamon-Elsevier Science Ltd, 2005-10)
There are many situations in which it is necessary to increase the capacity of structures in use. This need maybe either for a change of use or because the structures have suffered some damage or have shown little resistance ...
Numerical assessment of frp retrofitting systems for reinforced concrete elements
(Elsevier, 2007-12)
During their service life reinforced concrete structures can be exposed to mechanical loads and aggressive chemical or thermal agents that produce degradation of their mechanical properties. This results in a loss of ...
Bond-slip in reinforced concrete elements
(American Society of Civil Engineers, 2005-11)
A model for fiber reinforced composites that takes into account the fiber slipping is presented in this paper and applied to the analysis of reinforced concrete elements. The model is formulated within the framework of the ...
Validation of Performance-Dependent Failure Criterion for Concretes
(American Concrete Institute, 2011-05)
This paper focuses on the reformulation of the internal functions of the performance-dependent failure criterion (PDFC) for concrete, proposed by the authors, and its validation for different concrete qualities and stress ...
Study of the behavior of concrete under triaxial compression
(American Society of Civil Engineers, 2002-02)
An experimental study of the confined compression behavior of concrete has been performed using 150x300 mm cylindrical specimens subjected to hydrostatic pressure in a triaxial cell and axial loading through a servo-hydraulic ...
Recycled aggregate concrete: Localized failure assessment in thermodynamically consistent non-local plasticity framework
(Pergamon-Elsevier Science Ltd, 2017-01)
A gradient plasticity theory is extended to predict the mechanical failure behavior of concrete with recycled aggregates. A relevant feature of the novel constitutive formulation is its full consistency with the thermodynamic ...
Gradient and fracture energy-based plasticity theory for quasi-brittle materials like concrete
(Elsevier Science Sa, 2009-12)
In this work a thermodynamically consistent non-local gradient and fracture energy-based plasticity theory is proposed to simulate the failure behavior of concrete. The model incorporates two characteristic lengths, one ...
Numerical and analytical study of overpressures and impulses inside a masonry box subjected to external blast loading
(SAGE Publications, 2019-04)
Blast loads have attracted considerable attention in recent years due to accidental or intentional events involving important structures, which have occurred around the world. The activities related to terrorist attacks ...
Criminalización y jóvenes en Argentina: Reflexiones sobre la situación penal y alternativas al encierro carcelarioCriminalization and youth in Argentina: Reflections on the criminal situation and alternatives to prison confinement
(Universidad Nacional de Mar del Plata, 2021-12)
Históricamente y hasta nuestros días, los varones de sectores populares constituyen un grupo poblacional preponderante en el sistema carcelario argentino. En este artículo nos ocuparemos de reflexionar sobre la vinculación ...
Quantum entanglementin elliptical quantum corrals
(Elsevier Science, 2009-10)
Quantum corrals present interesting properties due to the combination of confinement and, in the case of elliptical corrals, to their focalizing properties. We study the case when two magnetic impurities are added to the ...
