Abstract
The present project is a part of an investigation on fatigue in
offshore structures in high-strength steel. The fatigue life of
plate elements with welded attachments is studied. The material
used has a yield stress of ~ 810-840 MPa, and high weldability and
toughness properties. Fatigue test series with constant amplitude
loading and with various types of stochastic loading have been
carried through on test specimens in high-strength steel, and -
for a comparison - on test specimens in conventional offshore
structural steel with a yield stress of ~ 400-410 MPa.A comparison
between constant amplitude and variable amplitude fatigue test
results shows shorter fatigue lives in variable amplitude loading
than should be expected from the linear fatigue damage
accumulation formula. Furthermore, in general longer fatigue lives
were obtained for the test specimens in high-strength steel than
those obtained in corresponding tests on joints in conventional
offshore structural steel.
