Estudo de métodos de reforço de pilares: encamisamento com concreto armado e confinamento com mantas de fibras de carbono

Abstract

In civil construction, there are various reasons for the necessity of reinforcements or repairs at construction sites, from faults in the execution of the project, maintenance or change of use. However, the main difficulty found by a the professional is the adequate choice of the reinforcement method, as each method has its own specificities. In this sense, the importance of this research is justified when carrying out a study about the reinforcement of reinforced concrete columns (RCC) and columns confined by carbon fiber reinforced polymers (CFRP). This research will consist of a descriptive bibliographic analysis of the methods, presenting the results for the design of a reinforced of a square section concrete column using both methods. Despite being a traditional method and having some calculation models presented in the literature, it has been concluded that RCC presents a difficulty in establishing a parameter due to the design variables having inferior development when compared to CFRP.
