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 ...
Contribuição ao estudo da realcalinização química em concreto convencional
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia CivilUTFPR, 2017-12-08)
This Work seeks to contribute in the search of alternatives for the treatment of carbonated concretes, having its focus on applying chemical realkalisation in two different ways. The main goal is to analyze the effectiveness ...
A finite element approach for predicting the ultimate rotation capacity of RC beams
(2013-07-15)
This paper presents a numerical approach to model the complex failure mechanisms that define the ultimate rotational capacity of reinforced concrete beams. The behavior in tension and compression is described by a constitutive ...
Mechanical response of fiber reinforced concrete overlays over asphalt concrete substrate: Experimental results and numerical simulation
(Elsevier, 2015-07)
Fiber reinforced concrete overlays are nowadays an alternative for repairing and reinforcing pavements. The contribution of concrete overlays strongly depends on the bond with the substrate. The fibers help sewing contraction ...
