Abstract

La présente invention concerne un corps structurel fonctionnel dans lequel les dommages d'une structure fonctionnelle ayant une fonction prescrite sont évités ou supprimés. La présente invention comprend : une structure fonctionnelle 1 qui a une fonction prescrite et comprend des sections évidées 11 et des sections saillantes 12 formées sur une partie de base 10 ; et des nervures 2 pour prévenir ou supprimer l'application d'une force depuis un côté de surface vers la structure fonctionnelle 1. Les nervures 2 peuvent être formées, par exemple, à une hauteur égale ou supérieure à la hauteur des sections saillantes 11. En outre, la résistance des nervures peut être supérieure à la résistance des parties saillantes dans au moins une direction rectiligne qui est parallèle à la surface comportant la structure fonctionnelle 1.
