[ES] Los polímeros reforzados con fibras de carbono se están utilizando cada vez más para el refuerzo de estructuras de hormigón, reemplazando a los sistemas tradicionales de refuerzo con acero. Esto es debido a sus altas resistencia y rigidez específicas, resistencia a la corrosión, ligereza y facilidad de manejo y puesta en obra. Este artículo presenta un estudio sobre el comportamiento de vigas de puentes reforzadas con bandas de CFRP mientras se mantiene el puente en servicio de manera que la estructura está sometida a cargas dinámicas con el adhesivo fresco. En los ensayos realizados se ha observado que las cargas dinámicas no afectan a la efectividad del refuerzo.
[EN] Carbon fibre reinforced polymers are increasingly replacing the steel reinforcing systems in the repair and strengthening of concrete structures thanks to their high strength/weight and stiffness/weight ratios, corrosion resistance, lightweight, and ease of handling and application. This paper presents a study on the behaviour of bridge concrete beams strengthened with CFRP sheets when the strengthening is made when traffic is acting so that the structure is subjected to dynamic loads while the adhesive is still fresh. No reduction in the effectiveness of the strengthening was observed in the tests.
