“…The ductility index was measured by two methods, (i) displacement ductility index (Al-Deen Bsisu et al 2015;Almusallam et al 2015;Ashour et al 2004;El-Gamal et al 2016;Hashemi et al 2008;Kim and Shin 2011;Tan et al 2009), and (ii) energy absorption ductility index Grace et al 1998;Hashemi et al 2008;Kim and Shin 2011;Orozco and Maji 2004;Oudah and El-Hacha 2012;Wang and Belarbi 2011;El Zareef and El Madawy 2018;Zou 2003) and is given in Table 6. It was observed that the displacement ductility index of CFRP strengthened specimens reduced by 9% to 35% as compared to the reference (unstrengthened) specimen.…”

“…Por un lado, se encontraron investigaciones que analizan el comportamiento de los elementos, vigas y losas con presencia de PRFV, frente a esfuerzos internos y externos mediante ensayos bajo flexión en dos, tres y cuatro puntos [3]; así como análisis de cargas sísmicas simuladas para garantizar el funcionamiento de anclajes [9]. Por otro lado, se presentan investigaciones que garantizan la adherencia de las barras PRFV con el concreto mediante ensayos de Pull-Out [10]; y ensayos de durabilidad trabajados en ambientes húmedos [11]. De las investigaciones mencionadas se concluyeron que las curvas de resistencia a flexión entre elementos con acero convencional y PRFV poseen un comportamiento similar; asimismo, referente a la durabilidad se demostró que el acero convencional en presencia de humedad se degrada constantemente a lo largo del tiempo hasta no llegar a aportar ninguna resistencia a los elementos, sin embargo para el caso de las barras PRFV al ser un material anticorrosivo este no tiende a degradarse y las presiones internas que hace el agua sobre este, simplemente crea una pequeña expansión de volumen de las barras de PRFV, lo cual resulta conveniente ya que se intensifica la adherencia entre barras PRFV y concreto.…”

“…An adequate ductility in reinforced concrete structure is very important to avoid a brittle failure of the structure by ensuring acceptable curvature at the ultimate limit state. Usually the ductility behavior of material is described as the capacity of the material to undergo sufficient plastic deformation without a significant loss in its load-carrying capacity [ 39 , 40 ]. The ductile behavior of reinforced concrete can be affected by several factors such as concrete compressive strength, reinforcement ratio, addition of fibers, aggregate type [ 30 , 41 , 42 , 43 ].…”
