Abstract

This paper aims to review Dante Bini’s career, as well as his form-resistant Binishell and other pneumatic construction systems. The role of Mario Salvadori in Bini’s international success works as the introduction to a broader discussion about the relationship between innovation in design and innovation in construction for shell and gridshell designers. The second part of the paper focuses, instead, on Bini’s double profile—architect and builder—which led him to develop his inventions both architecturally and as commercial products.

... During construction using this method, the shape of the structure is created by inflating a flexible membrane. Inflation can take place not only before the installation of the reinforcement and the application of concrete [15], but also thereafter [16,17]. This construction method is fast, simple, and inexpensive, but the disadvantage is that the range of available geometries is severely limited by the shapes that can be attained by inflating a membrane. ...

Despite all their advantages, load-bearing concrete shell structures with double curvatures are not frequently in use. The main reason is the complexity of their construction. In such a context, this article starts with a brief, critical review of existing technologies while their pros and cons are highlighted. Against that background, the authors propose a new approach for the highly automated fabrication of gridshell structures from variable modules reinforced with textile meshes. To demonstrate the feasibility of such a new technology, a demonstrator called ConDIT 1.0, a sphere-like shell structure composed of several frames, was designed and built. The frame modules were fabricated automatically using extrusion-based 3D printing and a printable, strain-hardening cement-based composite (SHCC). This article presents the design of ConDIT 1.0, the mechanical material characterization of printed SHCC, the technology of module production, the results of geometry verification for print modules using 3D scanning, and the procedure for the demonstrator’s assembly.

Thesis
L’obiettivo della ricerca è quello di definire le nuove frontiere dell’architettura in pietra. Tale obiettivo è perseguito secondo due modalità: una teorico-critica e una sperimentale/operativa. La tesi fornisce dunque un’ampia trattazione dei temi storico-critici connessi alla recente riscoperta dei materiali lapidei da parte del mondo della progettazione. Gli stessi temi sono alla base delle riflessioni concettuali e operative che hanno portato alla definizione di inedite strategie progettuali e costruttive volte alla realizzazione di alcuni prototipi sperimentali presentati nella tesi. Questi prototipi hanno il ruolo di dimostrare nuove possibili strade che possono portare in un prossimo futuro alla ridefinizione del ruolo dell’architettura in pietra all’interno della disciplina architettonica. Le nuove frontiere proposte presuppongono l’utilizzo dei più recenti strumenti di progettazione parametrico-computazionale, di fabbricazione digitale e robotica.

The Italian architect Dante Bini began his studies on shell structures during the 1960s. He developed and refined a form-finding and construction technique to erect a finished large-span reinforced concrete (RC) shell structure through the use of an inflatable membrane. This system was patented in 1964 under the name ‘Binishell’ and, over the following decades, it has been applied to construct hundreds of domes throughout the world. Bini’s invention fitted perfectly into the Italian post-war tradition, as he was, at the same time, the architect and builder of his structures. A few experimental tests were initially performed in Italy, and the first binishells that he lifted after the patent was filed were also constructed there. Since 1966, as a result of Mario Salvadori’s interest, Bini has been recognised internationally. In 1974 he moved to Australia after the NSW Department of Public Works asked him to realise a set of school facilities using the binishell technology. The construction of concrete shells has always been a difficult and expensive process – the preparation of formworks, as well as the installation of curved reinforcing rods before the concrete is poured, require experience and increase the construction costs. Such problems are particularly relevant in the Australian context, where the use of simple and rapid construction technologies has always been a priority. Dante Bini’s life and the binishell technology have been well documented from the historical point of view. However, a detailed report and contextualisation of Dante Bini’s Australian experience is still missing. A first attempt to survey the Australian binishells has already been published by the authors.2 The focus was on placing Bini’s early work within the previous research on pneumatic structures which began in the 1920s. The narrative of this paper instead starts in the 1960s, a period of great media success for RC shells. First, the origin of binishells is described as a natural consequence of three preceding inventions/patents. A timeline of the events that defined Bini’s emigration to Australia is then provided. A full list of the Australian binishells is also included, with detailed information on the archival sources, major alterations and current conditions.

Pier Luigi Nervi (1891-1979) is the most famous Italian engineer from the twentieth century. In 1952, having reached the peak of his career as a designer and entrepreneur in Italy, Nervi decided to enter the academic and professional world in the United States. Thus he undertook a path that would lead him to achieve fame in America: he promoted the circulation of his writings and works in the top American journals, strengthened his friendship with colleagues such as Pietro Belluschi, Marcel Breuer, Mario Salvadori and José Luis Sert, and held conferences in the most prestigious US universities. In 1962 Harvard University awarded him the Charles Eliot Norton chair. Between 1958 and 1976, thanks to the fame he had won, Studio Nervi succeeded in obtaining and managing important consultancy assignments for the construction of large structures in the United States. This book analyses how Nervi managed to export an idea of construction, characterized by unmistakably original buildings, of great commercial success. The twenty years of Studio Nervi's business in the United States embrace an important part of the history of the relations between post-war Italian engineering culture and American architectural and construction praxis as well as between academia and profession, and, not least, between clients and design studios.
Article
The Valle d’Itria area is characterised by the presence of dry stone vernacular structures called ‘trulli’. Although these represent a unique example of complex vernacular architecture, an in-depth analysis of their geometric features has not been carried out. This paper aims to fill that gap, and includes a review of their historical origin and a description of their most common building typologies. The building technique is reviewed in all its stages in order to point out the important relation between construction, structural behaviour and final shape of the building. Furthermore, morphologies and proportions of 30 existing trulli are investigated, by means of virtual three-dimensional models obtained by a combination of laserscanner and geo-radar surveying. The high-fidelity geometric models offer a new interpretation of their architecture. Moreover, this study highlights the lack of a systematic and consistent building methodology of trulli.

The Iglesia de la Virgen de la Medalla Milagrosa, or Miraculous Medal Church, exemplifies Félix Candela's mastery of discipline and play with the hyperbolic paraboloid (hypar) form. Candela designed and built this thin shell concrete structure in Narvarte, Mexico City between 1953 and 1955. His design concept was developed from his asymmetrical "umbrella" hypar form which he then tilted and warped to form half of each bay of the nave of Milagrosa. This paper first presents finite element analyses and a discussion of the structural form for each stage in the development of this design concept. Then an analysis of two adjacent bays is presented assuming a uniform thickness of 4cm (1.6in). In the actual structure, Candela adds a scalloping pattern which thickens the top ridge to 14 cm (5.5in). Through additional analysis with this added weight, this paper finds that significant tensile forces would develop without the scalloping ridge. The scalloped ridge therefore serves both structural and aesthetic functions.

The Swiss engineer Heinz Isler (1926-2009) was convinced that "formfinding is the most important factor in shell design" [7]. The present contribution starts with an appreciation of his very first lecture at the founding colloquium of IASS in 1959; then it mentions the follow-up presentation 20 years later after an extremely active and successful period. His three main formfinding methods are discussed. Isler's aversion against computer models is briefly mentioned. Finally a short remark on the personality of Heinz Isler is given.
Article
Architect, animator and educator Nic Clear challenges the contemporary notion of the pastoral to go beyond the simplistic binary opposites of the untainted rural idyll and the industrialised city. He explores how the narratives of the pastoral have provided a mainstay for science fiction and how this can be used to re‐imagine nature itself with the aid of advanced biotechnologies to create new architectures for the 21st century.
Article
This paper presents the author's experience in the design and construction of more than one thousand concrete shell structures over a 40 year period. The shell shapes presented are not based on geometric concepts, but result from shape-finding experiments. The shapes are created automatically by natural laws.
