Abstract The paper discusses the advantage of fiber-reinforced polymer (FRP) rebar for application in concrete because of its light weight, high strength, high corrosion resistance and durability. Different options of shaping the wave-like texture of FRP bars for concrete bonding are considered. The diameter measurement problem of ribbed FRP bars is examined, and a proprietary procedure is suggested to determine the equivalent diameter and elastic modulus of ribbed FRP bars. The tensile strength (889–1197 MPa) obtained herein is greater than the longitudinal flexural strength (566–822 MPa), which is due to the ribs, contrary to the case of plain bars. The elastic modulus values obtained (40–61 GPa) are in agreement with the known literature data.
