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 ...
Behaviour of steel-fibre-reinforced normal-strength concrete slender columns under cyclic loading
(2012-03-28)
The inclusion of ductility requirements is necessary to guarantee a safety design of concrete structures subjected to unexpected and/or reversal loads. It is important to outline that plastic hinges may develop in columns ...
An experimental study of steel fiber-reinforced high-strength concrete slender columns under cyclic loading
(2012-08-10)
Structural engineers usually limit the use of HSC columns to seismic active zones because of their britle behavior in comparison with NSC, even though it presents advantages both in terms of mechanics and durability. A ...
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 ...
