Resum
An adhesively bonded anchor for Carbon Fibre Reinforced Polymer (CFRP) tendons was investigated under the stress relaxation phenomenon. Experimental stress relaxation tests were undertaken on anchorages with four different adhesive thicknesses. Ten specimens were prestressed at three different initial tensioning forces and the displacement was kept constant. In addition, seven specimens were restressed when the loss load was stabilised and constant. The stress relaxation test setup used in this ...
