In this paper, the realization of a terminal for the storage of plastic materials, carried out by RDB for the Kt Natie Group, will be presented. The structural complex is characterized by a special reinforced concrete frame, constituted by cwed precast concrete beams which must allow the housing of aluminium silos where the plastic materials are collected. The realization and the assembling of the frame, which requires very low tolerances with respect to usual reinforced concrete strc, will be carefully described. The curved beams are desige by fllowing Eurocode 2 prescriptions, and their structural response is verified by performing non-linear finite element analyses, in which the non-linear mechanical behaviour is considered by implementing the PARC constitutive model into a fe Code. Comparisons between the theoretical (EC2) and numerical (nlfea) responses at SLS and ULS will be provided.
