Nervi e la prefabbricazione strutturale: lo Stadio Flaminio a Roma (1957-59)

The Stadium was designed by Pier Luigi and Antonio Nervi (1957-59) and was built for the Olympic Games hosted in Rome (1960). To ensure the rapidity of construction, the traditional construction site was accompanied by an area used exclusively to produce the prefabricated elements of the grandstand and the canopy (7,652 elements). The grandstand is based on a structure of 92 exposed reinforced concrete frames connected by secondary beams and the steps. Each step is formed from two prefabricated elements, based on a system patented by Nervi specifically for the Stadium. It consists of two prefabricated elements: a “U”-shaped load bearing element and the second element, supported by the first, forms the steps and seating. The canopy (27 m) is made of undulated prefabricated elements in ferrocemento lightened by round openings fitted with wired glass. The paper must highlight the specificity and originality of the solutions adopted by Nervi and his skill as a designer and builder.
