ABSTRACT: Rockfall barrier manufacturers test and certify their structures in accordance with the European Guideline ETAG 027/2008. The guideline does not define how the different components of the tested system must be manufactured, but it ensures that the entire tested “kit” is able to withstand a certain impact. After a short introduction of the ETAG 027, the paper underlines the main differences between test and real in-situ conditions, and introduces the new design approach proposed by the UNI 11211:4/2012. Moreover, the installation criteria are analyzed in order to define the best cost-effective fence. In conclusion, some considerations on the anchoring systems are presented.
RÉSUMÉ: Les producteurs des écrans pare-pierres testent et certifient leur structures en suivant la Ligne Guide Européenne ETAG 027/2008. Celle-ci ne définit pas comment les différent composants de la barrière doivent être fabriqués, mais assure que le « kit » testé est capable de contenir un certain impact. Après avoir introduit l’ETAG 027, l’article se focalise sur les différences principales entre les conditions qu’on trouve dans les stations d’essais et celles qu’on a vraiment sur chantier. Il introduit le nouveau approche de calcul proposé par UNI 11211:4/2012 et il analyse les critères d’installation afin de pouvoir choisir l’écran avec les meilleures avantages cout-bénéfices. En conclusion, des considérations sur les systèmes d’ancrage sont faite.
