Reforço estrutural à flexão com fibra de carbono em viga de concreto armado

Abstract

The application of carbon fiber, despite being an already known structural reinforcement method, has been gaining prominence and becoming increasingly present in resistant reinforcement solutions. For dimensioning, use an American standard ACI 440-2017. In this present course completion work, all steps will be demonstrated to design a structural reinforcement to bending in a reinforced concrete beam using carbon fiber and later compare it with a conventional structural reinforcement method. For this, a predimensioned reinforced concrete beam is used, in which the design moment is amplified, aiming at the need for reinforcement. The results show an increase in flexural strength with the use of carbon fiber, without intervention in force.
