SIMOES, Y. S. y SANTOS, C. F. R.. Contribution to the reinforced concrete beams degraded by fire: Comparative analysis between structural reinforcement with carbon fibers and steel sheets. Rev. ALCONPAT [online]. 2019, vol.9, n.1, pp.48-64. Epub 29-Sep-2020. ISSN 2007-6835. https://doi.org/10.21041/ra.v9i1.259.
This article aims to compare two techniques of structural reinforcement, carbon fiber and steel sheets, used for the recovery of reinforced concrete elements degraded by fire. It simulates the deterioration of a beam in a fire situation from a thermal numerical modeling and then the mentioned reinforcements are calculated. The carbon fiber required a smaller area compared to that for the steel sheet, due to its high mechanical resistance. As limitations, it is mentioned that the study is preliminary and involves only a thermal analysis of the beam, not considering the loading and its implications. It is concluded that the carbon fiber presents greater advantages with respect to reinforcement of beams.
