PROCEDE DE REALISATION D'UNE PIECE EN BETON ARME ET PIECE AINSI REALISEE
A method for producing a reinforced concrete part, having a tensioned portion subjected to pull stresses and tending to stretch under the load, and which includes a reinforcing frame with at least one tensioned longitudinal bar rigidly connected to the concrete by an adhesive connection that determines a tangential adhesive stress along the bar that varies on the basis of applied pull stresses. Each tensioned longitudinal bar has, on at least one portion of the length thereof, a discontinuous series of spaced blocking areas that each include a plurality of elements for anchoring into the concrete and which are separated from each other by a series of sliding areas, in each of which an increase in the adhesion stress above a limit value causes the bar to disengage, without disrupting the concrete, on at least a portion of the length between the two blocking areas with an extension of the bar corresponding to applied pull stresses, the extension being distributed over the entire length of the disengaged portion of the bar.
