Conoscenza e analisi delle strutture di Pier Luigi Nervi: un approccio multidisciplinare = Knowledge and analysis of Pier Luigi Nervi's structures: a multidisciplinary approach

The contribution illustrates the strategies adopted to perform the knowledge campaign on Hall C, built by Pier Luigi Nervi in Torino Esposizioni, between 1949 and 1950, and which belongs to the architectural heritage of the 20th century. The building was built by using both reinforced concrete and ferrocement elements, applying what for Nervi would later become a distinctive construction system of his work, combining the use of prefabricated elements in situ and cast-in-place elements. The in-depth analysis of the historical documentation has allowed the identification of the characteristic elements and the material differences of all structural elements in order to formulate a testing campaign as less invasive as possible, combining the extraction of samples with non-destructive tests. The contribution aims to illustrate the problems and challenges related to the realization of interpretative models of the built environment through the relationship between critical historical investigations and structural diagnostics and wants to be an example for an appropriate phase of investigation aimed at developing guidelines for the conservation of complex and iconic work.
