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 ...
Modeling reinforced concrete structures using coupling finite elements for discrete representation of reinforcements
(2018-09-15)
This paper presents an alternative methodology to represent rebars and their bond-slip behavior against concrete based on coupling finite elements. Among the main features and advantages of the proposed technique are: (i) ...
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 ...
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 experimentation for the optimal design of reinforced rectangular concrete beams for singly reinforced sections
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2016-03-01)
This paper presents a model for the optimal design of reinforced rectangular concrete beams for singly reinforced sections. It develops an analytical approach to the problem, based on a criterion of minimum cost and minimum ...
