NERVI'S CANTILEVERING STADIUM ROOFS: DISCIPLINE OF ECONOMY LEADS TO INSPIRATION

摘要

Although he came from a tradition that built magnificent palaces and churches, the Italian master builder Pier Luigi Nervi is arguably mostly known for his sports infrastructure. In this paper, we focus on his first (Giovanni Berta Stadium, Florence, 1930-1932) and last (Olympic Flaminio Stadium, Rome, 1957-1959) internationally widely recognized stadium with cantilevering roof. Through literature studies and structural analyses, we compare and contrast these two stadia on the basis of their structural and constructional efficiency, economy and design intent within the specific social-political context of the interbellum and post-World War Ⅱ era in Italy. The interpretation of these studies shows Nervi's clear progression from imitation, innovation to inspiration in his stadium design. More specifically shortage of construction materials and skilled labor did not constrain his projects but drove Nervi to design and build great structures.
