Description

The results of a large experimental programme is presented. Shots were performed with steel cylindrical missiles on reinforced concrete slabs. The scales used in this modeling were mainly one-third of the wall of a nuclear reactor but the effects of variation of following parameters were studied: missile velocity, its mass, ratio of the missile diameter to the thickness of the slab and characteristics of the steel reinforcement. An homogeneous perforation formula is proposed for the computation of the thickness of the reinforced concrete wall which is perforated by a given missile, and its validity range is specified. A comparison with others formulae found in the literature is made

Abstract (French)

On presente ici les resultats d'un important programme d'essais. Des tirs ont ete effectues sur des dalles de beton avec des projectiles d'acier cylindriques. On a surtout utilise une echelle d'un tiers par rapport a l'enceinte d'un reacteur nucleaire mais les effets de la variation des parametres suivants ont ete etudies: vitesse du projectile, sa masse, rapport du diametre du projectile a l'epaisseur de la dalle et caracteristique du ferraillage. Une formule homogene de perforation est proposee pour le calcul de l'epaisseur de beton arme qui sera perforee par un projectile donne et sa plage de validite est precisee. On la compare a d'autres
