The results of a two-university project to verify various material properties of a commercially available glass fiber reinforced polymer (GFRP) rod are presented. Among the basic test types performed were a uniaxial tensile test and a pullout test of 90 deg bent rods. Two types of test were used to evaluate the strength of the 90 deg bent rods. A specially designed pull-out test was used to determine the bond characteristics and the minimum development length. The uniaxial tensile test was performed to establish the following characteristics: ultimate strength, ultimate strain and modulus of elasticity. Epoxy coated steel rods were also tested as a bench mark. The experimental results suggest that this GFRP rod is suitable for reinforced concrete construction.
