Abstract
This paper considers current pratice in fatigue design of offshore concrete structures. Procedure for calculation of long term distribution of response to environmental loads from wind, waves and current is briefly discussed. The basis for fatigue design expressed in rules and requirements is described. Detailed evaluations for concrete, reinforcement, shear and bond with emphasis on cumulative fatigue are discussed. Areas where detailed recommendations are lacking or based on uncertain assumptions are pointed out and further research is suggested.
Résumé
On traite ici de la pratique courante du calcul en fatigue des ouvrages en mer en béton. On examine succinctement une procédure de calcul de distribution des réponses à long terme des sollicitations du milieu dues au vent, aux vagues et aux courants. On donne les principes du calcul en fatigue que l'on exprime en règles et exigences. On examine plus en détail des évaluations faites pour le béton, l'armature, l'effort tranchant et l'adhérence avec une attention particulière pour la fatigue cumulative. On met en évidence les zones pour lesquelles manquent des recommandations détaillées ou qui ne donnent lieu qu'à des hypothèses incertaines et l'on suggère ici de nouvelles recherches.
