Influencia de las varillas sintéticas en la capacidad resistente de los elementos tipo vigas

Abstract

The present investigation is based on determining the influence of the FRP bars (fiber reinforced polymers) on the resistant capacity of beam elements. We proposed a high strength concrete for making the testing beams and proceeded to compare different geometries of beams maded with FRP reinforcement bars and with a commonly used rebar of corrugated steel, which showed that there are certain predominant factors that influence the resistant capacity of beams with FRP reinforcement like the adherence of the bars, the diameter, their physical and mechanical properties and the geometry of the elements; Likewise it is concluded that a factor that was considered as one of the most important in the maximum resistance that a beam can reach such as the resistance of concrete was not as influential in the ultimate resistance of these elements.
