The art and science of building by Pier Luigi Nervi: A modern vision and a heritage to be preserved

AbstractThe legacy of Pier Luigi Nervi spans globally, showcasing excellence in construction and artistry. Conservation of his architectural marvels poses challenges due to material fragility and societal shifts. Preservation efforts require interdisciplinary collaboration among engineers, historians, and architects. Exhibitions on Nervi and UNESCO nominations highlight the importance of Nervi's work. Strategies for safeguarding his masterpieces are evolving, focusing on documentation and renovation. Although some structures faced damage during World War II, most remain structurally sound. However, common degradation of structural concrete, such as carbonation‐induced rebar corrosion, may affect structures in service since multiple decades, particularly in cases of inadequate concrete cover. Nervi's meticulous design and construction methods often mitigate such decay, especially in thin ferrocement elements. In addition, it must be considered that, as most of 20th century's structures, Nervi's structures were usually conceived without accounting for seismic actions, but only for static configurations, in accordance with the technical standards at the time. All this requires ongoing conservation and where needed rehabilitation efforts to ensure the cultural and social significance of Nervi's legacy is appreciated and preserved for future generations.
