The dome designed by P. L. Nervi in 1961 for the roof of the Palazzetto dello Sport in Flaminio district, Rome, has a remarkable feature: The ondulated shape of its edge provides significant enhancements of its structural behaviour. In particular, corrugation increases the bending stiffness at the edge providing a significance reduction of the dome thickness. This contribution deals with the mechanical analysis of corrugated shells. Attention is paid to the definition of their mathematical and geometrical descriptions and to the realization of a mesh suitable to perform FE analysis. Two significant case studies are considered: The no more existing rooftop of Fav-ini’s gas station in Sesto San Giovanni and the Nervi’s dome of Flaminio Palasport.

Abstract
The dome designed by P. L. Nervi in 1961 for the roof of the Palazzetto dello Sport in Flaminio district, Rome, has a remarkable feature: The ondulated shape of its edge provides significant enhancements of its structural behaviour. In particular, corrugation increases the bending stiffness at the edge providing a significance reduction of the dome thickness. This contribution deals with the mechanical analysis of corrugated shells. Attention is paid to the definition of their mathematical and geometrical descriptions and to the realization of a mesh suitable to perform FE analysis. Two significant case studies are considered: The no more existing rooftop of Fav-ini’s gas station in Sesto San Giovanni and the Nervi’s dome of Flaminio Palasport.
