Title (EN) STRUCTURAL ELEMENT MADE OF REINFORCED CONCRETE AND METHOD FOR ITS MANUFACTURE
(FR) ÉLÉMENT STRUCTURAL EN BÉTON ARMÉ ET SON PROCÉDÉ DE FABRICATION
Abstract:
(EN) A structural element (10) made of reinforced concrete comprising a first reinforcement (11), which first reinforcement (11) comprises at least one first continuous elongated element (12) which is made of steel for reinforced concrete and which develops mainly along the longitudinal extension of the structural element (10), and a second reinforcement (13), which second reinforcement (13) comprises at least a second continuous elongated element (14) which develops mainly along the longitudinal extension of the structural element, in which the area subtended to the force/displacement curve of the structural element (10) or of a specimen corresponding to the structural element subjected to flexural test with force acting along a substantially orthogonal direction to the longitudinal extension of the structural element or of the specimen replicating the structural element is greater by at least 20% than the area subtended to the force/displacement curve of a reference structural element replicating the structural element or of a reference specimen (200) replicating the specimen corresponding to the structural element, but lacking the second reinforcement (13), subjected to the same flexural test, in which the increase of the area is recorded substantially after the breaking point (C1÷C7) of the at least one first continuous elongated element (12).
(FR) La présente invention concerne un élément structural (10) en béton armé qui comporte une première armature (11), ladite première armature (11) comprenant au moins un premier élément allongé continu (12) qui est en acier pour béton armé et qui se développe principalement le long de l'extension longitudinale de l'élément structural (10), et une seconde armature (13), ladite seconde armature (13) comprenant au moins un second élément allongé continu (14) qui se développe principalement le long de l'extension longitudinale de l'élément structural, dans lequel la zone sous-tendue à la courbe force/déplacement de l'élément structural (10) ou d'un échantillon correspondant à l'élément structural soumis à un essai de flexion avec une force agissant le long d'une direction sensiblement orthogonale à l'extension longitudinale de l'élément structural ou de l'échantillon reproduisant l'élément structural est supérieure d'au moins 20 % à la zone sous-tendue à la courbe force/déplacement d'un élément structural de référence reproduisant l'élément structural ou d'un échantillon de référence (200) reproduisant l'échantillon correspondant à l'élément structural, mais dépourvu de la seconde armature (13), soumis au même essai de flexion, dans lequel l'augmentation de la zone est enregistrée sensiblement après le point de rupture (C1÷C7) du ou des premiers éléments allongés continus (12).
