Análise teórica e experimental do reforço à flexão em lajes de concreto armado utilizando fibra de carbono.

Abstract

Nowadays, it has become noticeable the great number of changes in structures that are used for purposes they were not designed for, as well as the emergence of pathologies. Therefore, there is a need to reinforce them in order to withstand higher loads than they were initially projected for. The current work evaluates the theoretical and experimental analysis of the usage of solid reinforced concrete slabs reinforced with carbon fiber, as well as the calculation and process execution. The advantages of using such method, as well as the design, test and analyses of the structures were also evaluated. The calculation procedure was done and compared with the results obtained experimentally. In this work, the correct application process of the reinforcement along with the comparison of increased resistance by the reinforcement were assessed. This type of reinforcement proved to be very efficient, since it does not add weight or increase the geometry of the reinforced structure, thus it results in a gain on the final resistance.
