RESUMO

Steel reinforcement replacement aims an increase at the durability of structures with corrosion and electrical magnetic problems. But, inserting a new material at the civil construction industry demands specifications of its composition, behavior and procedures for its utilization. This work is a flexural behavior analysis of reinforced concrete beams reinforced with GFRP bars. To make this, a technical literature research was made considering the pioneer until the most recent researches, and components and concrete reinforced beams tests were done. GFRP bars properties tests went from the determination of its strains X stress diagram to its tension resistance. GFRP reinforced beams were submitted to four points flexural tests and the results compared with a CA-50 steel reinforced beam also submitted to the flexural test. The specimens showed the influence of GFRP properties at the behavior of the structure. For example, longitudinal bars large strains and the large displacement of the beam were determined by GFRP bars low longitudinal elastic modulus. Continuing the studies evolving GFRP bars is certainly a need. New researches might be able to design a way to use the composite properties to improve the structure behavior
