The use of continuous fiber reinforced polymer (FRP) bars as an internal reinforcement for concrete has gained attention due to its non-corrosive properties, high resistance, requiring electromagnetic transparency. On the other hand, the brittle behavior and low modulus of elasticity of FRP bars limit their application and diffusion in the civil construction market. From this perspective, this work evaluates, firstly, the increase of ductility in GFRP (glass-fiber reinforced polymer) reinforced concrete beams by adding dispersed alkali-resistant (AR) glass fibers to the cementitious matrix and/or by confinement of the concrete in critical regions with the use of GFRP stirrups. To accomplish this task, the results of tests performed on eight statically determinate beams under four-point bending are reported and discussed, four of which are under-reinforced and four are over-reinforced. In general, the strategies adopted were successful only for the overreinforced beams, whose failures were characterized by the formation of a compression wedge and large displacements before rupture. For ductility evaluation, two distinct methods were adopted: one based on energy (ductility index, (micro)E) and another based on deformation (performance factor, (micro)M). For under-reinforced beams, the performance factor through curvature and the performance factor through deflection led to greater ductility increments for the beam with the addition of dispersed fibers due to the tensile stiffening effect, while the ductility index did not lead to good results. For the over-reinforced beams, the performance factor through curvature and the ductility index were able to describe the greater ductility increments for the confined beams, while the performance factor through deflection resulted in a greater ductility increment for the beams with discrete fiber addition. In a second step, the capacity of redistribution of moments in three statically indeterminate GFRP reinforced concrete beams with two spans and with a higher lower reinforcement ratio was evaluated for two different configurations of transverse reinforcement and for the use of fibers. It was possible to observe an increase in the positive moment of 30 percent (center of span) and a reduction in the negative moment (central support) greater than 60 percent, when compared to the elastic moments, confirming the influence of the reinforcement configuration on the distribution of internal forces.
