In the present study, a beam and a column were dimensioned, considering
reinforcement with glass fiber reinforced polymer (GFRP) bars and conventional
steel bars. The same span and environmental conditions were considered for
both the beams, and they had identical cross-sections. Additionally, another
steel-reinforced beam was calculated using the same parameters as the
previous beams, but with an increased height to fall within domain 3. Based on
the obtained results, it was possible to compare the reinforced concrete beam
with GFRP bars to the one reinforced with steel, and it was observed that
reinforced concrete with GFRP bars proved to be an equivalent option for
everyday construction. The area of GFRP bar reinforcement was 64.86% larger
than that of steel, considering the same beam sections. Furthermore, the
column with GFRP bars required a greater longitudinal reinforcement area
compared to the steel-reinforced column under the same conditions and is
considered slightly more expensive.
