Struc2000 Posted October 20, 2019 Report Share Posted October 20, 2019 Bonjour à tous Une question que je n'ai pas assez compris à ce jour. La durée d'application de la combinaison d'action pour le calcul de la contrainte de calcul du béton La formule : fbu = 0.85 fc28/teta x gama b On nous dit que ce fameux 'teta' est égale à : 1 si la durée d'application est sup à 24 heures 0.9 si entre 1heure et 24 heures 0.85 si inf à 1 heure La question : c'est quoi exactement cette durée probable d'application de la combinaison d'actions considérée ?? Ce que je sais c'est que les actions permanente sont appliquées en permanence. et les actions d'exploitation s'applique pour de longues durées. Alors c'est quoi cette histoire de 24 heures. Merci 1 Quote Link to comment Share on other sites More sharing options...
