Abstract:
Through analyzing the composition and physics mechanics performance characteristic of FRP tendons, the difference between FRP tendon and steel tendon was compared, the applicability and the future of FRP tendon in engineering structure were pointed out. Through experiments study, the effects of local bending to ultimate tensile strength, loading velocity rate and process to elastic modulus of FiBRA style AFRP tendons were analyzed, and stress levels to relaxation of FiBRA style FRP tendons were researched, and the formulas for calculating the relaxation rate of FA11, one spec of FiBRA tendon, were obtained. The results show that local bending may reduce the ultimate strength of FRP tendons, and the weave of FiBRA style AFRP tendon leads that the elastic modulus can only stabilize gradually and the total relaxation is more. These shortcomings should be noticed cautiously in practice.
