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 ...
Ductility analysis of RC beams considering the concrete confinement effect produced by the shear reinforcement: A numerical approach
(2017-01-01)
In this paper, a simplified numerical approach to study the influence of the confinement effect provided by transversal reinforcement on the ductility behavior of RC beams in bending is proposed. A unidimensional FEM ...
Evaluation of passive confinement in CFT columns
(ELSEVIER SCI LTD, 2010)
This paper presents the experimental results of 32 axially loaded concrete-filled steel tubular columns (CFT). The load was introduced only on the concrete core by means of two high strength steel cylinders placed at the ...
Confinement of reinforced concrete compression members using bow-tie CFRP reinforcement
(2015)
The 2010 Maule earthquake produced brittle compression failure of reinforce concrete (RC) walls, due to high axial load, deficient detailing of boundary elements, and the use of thin and slender walls. To prevent new ...
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 ...
Preloaded RC columns strengthened with high-strength concrete jackets under uniaxial compression
(SPRINGER, 2008)
Although use of high-strength reinforced concrete (RC) jackets has become common practice worldwide, there are still two unresolved issues regarding the contribution of the original concrete and the effects of existing ...
Comportamento de pilares mistos preenchidos com concreto de resíduos de concreto submetidos a compressão axial centrada: efeito do teor de substituição e da forma de aplicação da força
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Civil - PPGECivCâmpus São Carlos, 2020-02-20)
Seeking to mitigate the environmental impact of civil construction, investigations focused on concrete waste use in the production of new concrete are pushing the Brazilian researches. However, despite significant advances ...
