Civil constructions have a limited useful life, eventually in some period of structures need to be reinforced or repaired, and may have their modified use of the original. There is a variety of forms of reinforcement or repair already consecrated as, increased the section of the piece, reinforcement of complement, addition of plates or metallic profiles and others, being constantly developed new materials. However, due to the lack of knowledge of the professionals of the area and the lack of studies of efficiency, it reinforces its application is still little used. This research has as purpose an analysis of the efficiency of the structural reinforcement with carbon fiber in short pillars submitted to axial compression. Four different types of models were tested, without reinforcement and without reinforcement, without reinforcement and with reinforcement, with reinforcement and one layer of reinforcement and with reinforcement and two layers of reinforcement. At the end it was observed that the application of the reinforcement increased the resistance to compression as well as a small increase when included armor to the element.
