Method for applying a reinforced composite material (12), such as a fibre reinforced polymer (FRP) laminate or a steel reinforced polymer (SRP) laminate or a steel reinforced grout (SRG) composite, to a structural member (10). The method comprises the steps of: applying a curable adhesive (14) to a surface of the structural member (10) and/or a surface of the reinforced composite material (12), and bringing said surfaces into contact. A pre- stressing force, Pmax, is directly or indirectly applied to the reinforced composite material (12). The pre-stressing force, Pmax, to which a treatment length, LT, of the reinforced composite material (12) is subjected is then decreased so that the reinforced composite material (12) along the treatment length, LT, will be less pre-stressed than the reinforced composite material (12) adjacent to the treatment length, LT, when the adhesive has cured.

La présente invention concerne un procédé permettant l'application d'un matériau composite renforcé (12), tel qu'un stratifié polymère renforcé de fibres (FRP) ou un stratifié polymère renforcé d'acier (SRP) ou un composite de coulis renforcé d'acier (SRG), à un élément structurel (10). Le procédé comprend les étapes suivantes : l'application d'un adhésif durcissable (14) à une surface de l'élément structurel (10) et/ou une surface du matériau composite renforcé (12), et la mise en contact desdites surfaces. Une force de précontrainte, Pmax, est directement ou indirectement appliquée au matériau composite renforcé (12). La force de précontrainte, Pmax, à laquelle une longueur de traitement LT, du matériau composite renforcé (12) est soumise est ensuite réduite de sorte que le matériau composite renforcé (12) conjointement avec la longueur de traitement, LT, sera moins précontraint que le matériau composite renforcé (12) adjacent à la longueur de traitement, LT, après le durcissement de l'adhésif.
