Felix candela miami8/16/2023 The Belgian structural engineer Andre Paduart designed and built 465m of such warehouse sheds along the Docks in Antwerp. The fast port reconstruction after the destruction of the Second World War demanded warehouse structures and construction techniques that were cost-effective. A fine example of such shells can still be found on Kaai 105, 107 and 109 at the Albert Dock in Antwerp, a port city in the North of Belgium. Utilitarian spaces such as warehouses and aircraft hangars were roofed with these shells. The German contractor firm Dyckerhoff and Widmann AG first developed analytical theories to analyze shapes, related to domes (spheres) and vaults (cylinders). The initial shell designs were entirely envisaged, analyzed and built by engineers, interested in spanning large spaces without intermediate supports in the most material efficient manner. The early shell period 1912-1940: utilitarian cylindrical shells in the Port of Antwerp White Cabinet and White Table, Marcel Broodthaers, 1965 In this post, I briefly describe the history of civil shell design and construction in Belgium in the 20 th century and in particular I focus on the work of the civil engineer Andre Paduart (1914-1985), who operated in the same time and geographical space as Marcel Broodthaers. These phases also happen to span the biological life of Belgian artist Marcel Broodthaers (1924-1976) who is, among other projects, known for his assemblies of shells of eggs and mussels. Their evolution in that century can be marked by 3 phases. Egg shells are amazingly strong under uniformly distributed loading.Ĭivil shell structures mostly originated in Germany in the beginning of the 21 st century, spurred by development of analytical “shell” theory and reinforced concrete. To further stiffen against impact loading, some shells in nature are equipped with corrugations like many tropical sea shells. The shell can be very slender and sustain high distributed loads because its form follows the flow of internal loading. A large chicken egg for example is about 4.5cm and has a typical shell thickness of 0.05mm ( slenderness ratio of 900) and could theoretically sustain a load of 14kN (that is the weight of about 14 American football players). In particular the avarian egg shell and the sea shell come to mind. The efficiency of shells is often exemplified by examples of nature. Adriaenssens, invited by the Broodthaers Society of America, will be telling on Tuesday, March 28, 6:30–8pm at Hauser & Wirth Bookshop and Roth Bar, 548 West 22nd Street, New York, NY 10011. This post reflects some of the storyline that Prof.
