Abstract

La présente invention concerne une structure en bois renforcée parasismique avec introduction d'armatures de précontrainte dans celle-ci et son procédé de construction et, plus particulièrement, une structure en bois renforcée parasismique avec introduction d'armatures de précontrainte dans celle-ci et son procédé de construction qui utilisent du bois d'œuvre d'éclaircissage ou du bois d'œuvre court dans un élément de pilier en bois utilisé pour la structure en bois, ce qui permet d'empêcher le gaspillage des ressources et de réduire au minimum un taux de perte du bois d'œuvre, et qui permettent à l'élément de pilier d'être accouplé de manière stable au sol ou à la partie supérieure d'une pierre angulaire au moyen d'une pièce de fixation de pilier selon une manière d'accouplement de pièce à pièce et qui comprennent des armatures de précontrainte installées dans un élément de poutre tout en permettant à l'élément de pilier et à l'élément de poutre d'être accouplés selon la manière d'accouplement de pièce à pièce, ce qui permet d'améliorer la stabilité de la structure en bois à l'apparition de tremblements de terre et de typhons.
