The use of fiber reinforced polymers (FRP) as a strengthening method for concrete structures has gained prominence, being a technique that tends to be widely used as a non-destructive, efficient and easy to apply strengthening method. However, because it is a recent technique, many standards from different countries do not yet contemplate this type of reinforcement, making further studies necessary on the subject. In this work six reinforced concrete columns were analyzed, two of which functioned as reference and four received strengthening through the application of carbon fiber reinforced polymer (CFRP) with variations in fiber orientation and load eccentricity, with the objective of verifying the efficiency of each type of confinement for situations of compression and flexural compression. For the computational analysis, the ANSYS software was used with the aid of the ACP plug-in (ANSYS Composite PrepPost), comparing the results obtained in the simulation to the experimental results. Through the finite element analysis, it was possible to conclude that the strengthening proved to be efficient in all situations. It was also possible to observe that the behavior of the simulated specimens represented reality well.
