Macro-Kinematic Modelling of Continuous Deep Beams

Abstract

Cet article présente une approche macro-cinématique permettant de décrire les schémas de déformation avec fissures diagonales des poutres-voile continues. On montre comment une poutre continue formée de deux travées symétriques et supportant deux charges concentrées égales peut être modélisée à partir de seulement deux degrés de liberté. Ce modèle cinématique est combiné avec une théorie cinématique à trois paramètres (3PKT) qui permet de calculer la résistance au cisaillement de poutres-voile, les réactions d’appuis à la ruine et la capacité de déformation de poutres-voile continues. Cette approche a été appliquée à quatorze essais de cisaillement issus de la littérature avec différentes hauteurs de section, différents arrangement de l’armaturage longitudinal et différentes quantités d’armaturage de cisaillement. Les résultats montrent que cette approche macro-cinématique basée sur deux degrés de liberté reproduit correctement les tendances observées dans la capacité ultime au cisaillement des spécimens.
