Cyclic tensile tests on prestressing strands eedded in …

2020/4/30· The fatigue behaviour of prestressed concrete beams, subjected to cyclic bending loads, depends primarily on the fatigue of the eedded prestressing strands. In current code provisions, e.g. in EC2 [] and MC2010 [], the fatigue life of strands is described by S–N curves only based on the relationship between stress range in the strands and nuer of load cycles until failure.
