High Fatigue Performance

  • Multiple full size tests on cable sizes from 7 to 156 strands
  • The system has been successfully tested in standard tests with a stress range of up to 200MPa at an upper stress limit of 45% GUTS and at 2 million load cycles with anchorages inclined by 0.6°. In addition, full size tests have been performed successfully with an upper load of up to 60% GUTS, up to 10 million load cycles and a stress range of up to 250MPa
  • Tests on single strands under reversed cyclic flexural loading with 45% and 60% GUTS, 2 million load cycles with anchorages inclined by 3.0° and additional angular deviation between ± 10mrad and ± 35mrad

The leak tightness of the anchorage area has been demonstrated for the complete system and even meets stringent fib and Setra requirements with:

 

  • Up to 3m water head
  • Several load cycles in the longitudinal and transverse direction
  • Temperature cycling 20–70°C
