- Soft Pre-stressed PET profiles as reinforcing fibers in structural elements made of concrete Sergio Márquez-Domínguez Edgar Mejía-Sánchez Jesús Antonio Arenzano-Altaif Gerson Omar Martínez-Guevara Dante Tolentino Ingeniería Pre type Beams stress Concrete The inclusion of pre-stressed PET profiles as reinforcing fibers in structural elements is proposed. The PET-profiles are placed in a unidirectional and bidirectional fiber matrix with soft pre-tensioned condition that they could have advantages in structural members made of concrete in some precise applications, for instance, road safety barriers. A universal machine (WDW-200E) is used to test PET-profiles with different width, knots and even other conditions. The desired PET profile is chosen and the concrete mixture is designed under the ACI standard guidance. Pre-stressed PET-profiles are included in wood molds shaped in beam-type and subsequently flexural strength is estimated. Furthermore, experimental tests results are presented for PET-profiles as structural reinforcement of beams made of concrete under pure flexural. Finally, a probabilistic model is used to estimate the PET contribution in terms of exceedance of the rupture modulus. 2018 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49659032020 https://www.redalyc.org/journal/496/49659032020/ https://www.redalyc.org/journal/496/49659032020/html/ https://www.redalyc.org/journal/496/49659032020/49659032020.epub https://www.redalyc.org/journal/496/49659032020/movil 10.15446/dyna.v85n206.71805 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.206 Vol.85
