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 ...
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 ...
Modeling concrete like materials under sever dynamic pressures
(Pergamon-Elsevier Science Ltd, 2015-02)
The behavior of concrete, as well as that of all cohesive-frictional materials, is characterized by a strong dependence on hydrostatic pressure and strain rate sensitivity. The stress–strain response is nonlinear and, ...
Influence of concrete strength and length/diameter on the axial capacity of CFT columns
(ELSEVIER SCI LTD, 2009)
This paper presents an experimental analysis of the confinement effects in steel-concrete composite columns regarding two parameters: concrete compressive strength and column slenderness. Sixteen concrete-filled steel ...
Reliability-based evaluation of design code provisions for circular concrete-filled steel columns
(ELSEVIER SCI LTD, 2009)
This paper presents an investigation of design code provisions for steel-concrete composite columns. The study covers the national building codes of United States, Canada and Brazil, and the transnational EUROCODE. The ...
Displacement and curvature estimation for the design of reinforced concrete slender walls
(Wiley-Blackwell, 2016)
Previous earthquakes, such as the 2010 Maule earthquake in Chile, have demonstrated the need to establish suitable predictors of compressive or tensile strains in concrete or steel in reinforced concrete shear walls, which ...
Estudio experimental de probetas de hormigón confinadas con materiales compuestosExperimental study of concrete cylinders confined by composite materials
(Universidad Tecnológica Nacional, 2010)
Existen numerosas situaciones en las que es necesario mejorar la capacidad portante de elementos sometidos a solicitaciones de compresión, como columnas y pilas de puentes. El refuerzo externo con polímeros reforzados con ...
Thermodynamically consistent elasto-plastic microplane formulation for fiber reinforced concrete
(Elsevier, 2016-03)
In this work a thermodynamically consistent elasto-plastic microplane constitutive theory, aimed at simulating the failure behavior of Steel Fiber Reinforced Concrete (SFRC), is developed. The continuum (smeared crack) ...
Septarian carbonate concretions in the Permian Rio do Rasto Formation: Birth, growth and implications for the early diagenetic history of southwestern Gondwana succession
(Elsevier B.V., 2015-08-01)
Between the Late Carboniferous and Early Triassic, the southwestern Gondwana supercontinent was characterized by the development of a huge intracratonic basin. A large confined epeiric sea and the accumulation of a ...
