Abstract (EN): Fibre reinforced polymeric (FRP) composites are nowadays utilised to fabricate reinforcing bars for concrete load bearing elements. Among them, glass fibre reinforced polymers (GFRP) with vinylester matrix are widely used for beams and plates reinforcement. An experimental program has been performed to determine the main tensile properties needed to carry out the design of concrete elements. The most important test results obtained from the tensile tests on samples made of glass fibres and vinyl ester resins are analysed in the present paper. Three sets of 12 bars with diameters of 16, 12, and 8 mm have been loaded in tension to determine the ultimate tensile strength, the elastic tensile modulus and the ultimate tensile strain. A numerical modelling has been done to analyse the stress distribution in the bar ends and along the principal test segment of the tensile specimens. It has been realised that the experimental work and the numerical modelling provide a suitable description of the GFRP reinforcement bars enabling the determination of the essential properties needed for design.
