Abstract:

This article aims to compare two structural reinforcement techniques, carbon fibers and the metal sheets, used to recovery of the degraded reinforced concrete elements. It will be simulated the deterioration of a beam in a fire situation from a thermal numerical modelling and then the two mentioned reinforcements are calculated. The carbon fibers required a smaller area compared to that obtained for metal sheets, due to its high mechanical strength. This work is a preliminary study that involved only a thermal analysis of a beam, not considering the loading and its implications. It is concluded that structural reinforcement in carbon fiber presents greater advantages than metal sheets for recovery of degraded reinforced concrete beams.
