Description
  • The paper deals with long-term performance and material characterization of GFRP tendons in pre-stressed concrete structures. Regarding pre-stressed GFRP tendon itself relaxation of this composite material has not been fully scanned so far. Therefore relaxation test was carried out in order to describe stress-time relaxation curve for GFRP tendon. It has been verified experimentally that tensile stress decreases in the GFRP tendon when deformation is kept constant. Stress loss after 28 days reached 7,3 %. Loss after 130 days reached almost 10,5 %. Nevertheless the most important characteristic of curve geometry of the pre-stressing force loss in GFRP tendon was carried out. Aim of the research was also to develop a visco-elastic predictive model of stress-decreasing curve through the Kelvin and Maxwell chain. This model should help us to describe numerically a relaxation curve for different fibre reinforced polymers and to predict losses without long-term testing.
