The problem of shear capacity of reinforced concrete members has engaged the attention of many researchers. Despite this, it has not yet been understood fully because of the fact that the behaviour of concrete structures under variable stresses is very complex. Moreover, little information is available regarding both the shear stress contribution of different elements and the failure mode mechanisms of high strength reinforced concrete (HSRC) members. In this paper an attempt has been made to discuss in some detail these aspects in the context of high strength reinforced concrete beams. In addition, new expressions have been developed to predict the ultimate shear stress of high strength reinforced concrete beams.

Le problème de capacité de cisaillement des éléments en béton armé a toujours retenu l’attention de nombreux chercheurs. Malgré cela, on ne l’a pas encore complètement résolu, parce que le comportement des structures en béton soumises à différentes contraintes est très complexe. De plus, il existe peu d’informations sur la contribution des contraintes de cisaillement des différents éléments et les mécanismes de rupture des poutres en béton armé à haute ténacité. Dans cet article, nous entamons une discussion détaillée de ces aspects, dans le contexte des poutres en béton armé à haute ténacité qui subissent une défaillance critique du cisaillement. Nous y ajoutons également de nouvelles expressions développées pour prédire le taux de cisaillement critique de ces poutres.
