Long term behaviour of concrete structures reinforced with pre-stressed GFRP tendons
Original language description
This paper shows two long-term experiments. One of them is relaxation of pre-stressed GFRP tendon and the second one is creep of a concrete slab reinforced with pre-stressed GFRP tendons. The first experiment shows that relaxation of pre-stressed GFRP tendon is very high. A GFRP tendon was pre-stressed up to 37 % (237,9 MPa) of it's tensile strength (654,0 MPa). Decrease of tensile stress when the experiment was closed (after 132 days) was about 10,5 %. Creep of the slab shows long term behavior of structure reinforced with GFRP tendons. The creep test was ended after one year. Concrete slab pre-stressed with GFRP tendons was subjected to four point loading test with a constant load. During the year deflections and strain were recorded. Therefore creepcurve is plotted.
