Abstract

Poutre de longueur 2 L destinée à travailler en appui simple et à supporter une charge qui lui est appliquée dans une zone médiane; la distance D entre le niveau point de niveau maximal d'application de la charge et le niveau du point de niveau minimal de la ligne inférieure de son profil et la distance Ds entre le niveau du point de niveau maximal d'application de la charge et le niveau du point de niveau maximal de la ligne supérieure de son profil y sont mesurables. Cette poutre est essentiellement caractérisée en ce que la ligne inférieure du profil d'une demi-poutre, au moins dans la zone médiane d'application de la charge, est un arc de cercle de rayon R = L **4 2Root ;Di /Ds .
