Abstract

L'invention concerne un procédé de fabrication d'un élément de structure (100) comportant : - une étape de mise en tension d'au moins un tendeur (120), - une étape de coulage autour de chaque tendeur d'un matériau à l'état fluide, - une étape de séchage dudit matériau qui, en durcissant, forme un corps allongé (110) présentant une fibre moyenne (F100), et - une étape de libération de chaque tendeur de façon à ce que le corps allongé soit comprimé longitudinalement selon un axe de compression (A100) distinct de la fibre moyenne. Selon l'invention, préalablement à l'étape de libération, il est prévu une étape de mise en charge de l'élément de structure de façon à lui appliquer un effort provisoire (T100, T100') transversal à l'axe de compression.
