Check out this video and like it on YouTube. By 2050, 70% of the world’s population will live in cities. Structural engineers envision, design and construct the bridges and long‐span buildings those city dwellers depend on daily. The construction industry is one of most resource‐intensive sectors, and yet our urban infrastructure continues to be built in the massive tradition in which strength is pursued … Continue reading Prof. A’s Tedx Talk: Designing for strength, economy and beauty
In November 2016, the ZKM – Zentrum fuer Kunst und Medien – Centre for Arts and Media – in Karlsruhe, Germany, inaugurated its exhibition on the works of Frei Otto entitled “Frei Otto – Thinking by Modeling” (November 05, 2016 – March 12, 2017): an exhibition unprecedented in terms of conception and extent, curated by Prof. Georg Vrachliotis. In the year before, Frei Otto had passed away, while in the same year he had been awarded the prestigious Pritzker Prize for architecture. As a result, the attention of architects, engineers and designers worldwide has been refocused on the personality, the works and the achievements of Frei Otto. The opening of the exhibition was widely picked up, attracted a lot of visitors and comes along with several “special events”, one of them being a symposium which will be held on January 26-27, 2017.
The works of Frei Otto and his research teams play an active role in current design of architecture and engineering. They are often referred to when lightweight structures or bionically inspired designs are discussed. The current attention on Frei Otto,his insights and merits should be interpreted as contributions to our heritage, prospect and responsibility. His exclamation “Stop building the way you build!“, formulated during a lecture in 1977 , is still reverberating. This outcry can be taken as an inspiration for many disciplines, be it architecture, engineering, biology or social sciences.
Frei Otto and the Institute of Lightweight Structures in Stuttgart
The establishment of the “Institute of Lightweight Structures” at the University of Stuttgart, Germany, was a starting point to a “time line” of lightweight structures at this location. Fritz Leonhardt called Frei Otto, who was at that time living and working in Berlin, to Stuttgart University. Fritz Leonhardt (1909 – 1999) was the designer of the Stuttgart television tower which was the first of its kind being constructed in reinforced concrete, the author of books dealing with “aesthetics” of bridges, and pioneer in the field of designing structures in reinforced concrete. Leonhardt had published his thoughts about lightweight structures as a “demand of our times” in 1940 , a time facing material scarcity during a devastating war which had been triggered by Nazi-influenced Germany. The lack of material, or the restriction to a certain kind of material, can be taken as a source of inspiration for lightweight construction: Eladio Dieste, Felix Candela and Robert Maillart developed their unique aesthetics by this kind of limitation. Fritz Leonhardt was aware of this special quality and in that spirit he called Frei Otto to be Professor at the the Institute of Lighweight Structures IL at Stuttgart University.
During this time, Frei Otto was dealing with the detailed design of the German pavilion for the Expo Montreal in 1967, a piece of architecture which was path breaking in many ways. A test building of the Expo roof, prototype of a cable net structure, was to become the place of location of the IL.
Joerg Schlaich was the successor of Fritz Leonhardt as Professor at the University of Stuttgart. Werner Sobek assumed the chair of Frei Otto at the Institute of Lightweight Structures in 1994. In 2001, he was additionally appointed as successor to Joerg Schlaich’s Chair. The two chairs were merged to become the “Institute of Lightweight Structures and Conceptual Design” ILEK. In 2015, Werner Sobek was awarded the “Fritz Leonhardt Prize”, a distinction awarded every three years to an engineer in recognition of outstanding contributions to the area of structural engineering. In a very emotional speech, Sobek stated his view of the necessity of lightweight structures, based on very descriptive and startling numbers .
The circle is closing: the need for lightweight structures, be they named material-efficient or low-carbon-footprint, is even more relevant in the beginning of the 21st century. Frei Otto initiated a center of knowledge which reached out to the world.
“Thinking by Modeling” – the exhibition
The exhibition is set up in two large-scaled rooms of the “ZKM” (Zentrum fuer Kunst und Medien – Center for Arts and Media) museum in Karlsruhe. The building itself was originally built as a munition factory and is a protected monument with classical elements of industrial architecture. It hosts the ZKM since 1997.
The city of Karlsruhe is also the location of the “saai” (Suedwestdeutsches Archiv für Architektur und Ingenieurbau – Southwest German Archive of Architecture and Engineering), where Frei Otto’s works have been archived after his passing away.
Due to the initiative of Prof. Georg Vrachliotis, Professor at the KIT Karlsruhe, this impressive exhibition has been realized.
The exhibition is constituted by four elements: model landscape, open archive, cosmos, and projection.
Last week I had the opportunity to travel to Tokyo for the 2016 IASS Symposium, as one of the award recipients for the IASS design competition for an alternative New National Stadium. While I spent most of my time at the conference sessions, I still got to see many incredible structures while on a tour organized by IASS. Here are some highlights:
The Prada store by Herzog & de Meuron and Yakenaka Corporation features a lattice of H-sections that serves as both the lateral structural system and as the façade.
While on the tour, we got to see the Yoyogi Indoor Stadiums built for the 1964 Olympic Games. This was a very special visit, not because the 2020 Tokyo Olympic facilities were a major talking point at the conference, but because chief engineer Mamoru Kawaguchi was there to explain the project to us. At the time, Dr. Kawaguchi worked at Yoshikatsu Tsuboi’s firm, which designed the stadiums together with architect Kenzo Tange.
MoMA’s exhibit on Japanese architecture (through July 31, 2016) examines the “constellation” of influence in the country’s early-21st-century architecture and design community, but perhaps not so explicit in the exhibit are 1) the structural engineers’ parallel relationships of influence and 2) the structural engineer’s role in collaborating with architects to produce these works. In an effort to explore these characteristics of structural engineering influence in Japan, Prof. Guy Nordenson (of Princeton University and Guy Nordenson and Associates) and Prof. John Ochsendorf (of MIT) organized a symposium, titled “Structured Lineages: Learning from Japanese Structural Design,” which brought together some of the top structural designers from both Europe and the US for discussion.
Most of the lectures presented by the guests focused on the works and experiences of specific Japanese structural designers and educators such as Yoshikatsu Tsuboi, Mamoru Kawaguchi, Masao Saitoh, Gengo Matsui, Toshihiko Kimura, and Mutsuro Sasaki. Each half of the symposium brought the speakers together for a vibrant panel discussion moderated by our Prof. Sigrid Adriaenssens and MIT’s Prof. Caitlin Mueller. The final panel discussion welcomed Prof. Sasaki himself to the mix.
Several fruitful discussions and themes arose from the independently-constructed lectures. Reflecting the literal implications of “lineages,” Prof. Seng Kuan referenced the traditional lineage model in which Japanese arts and crafts get passed down for seven or more generations. As Prof. Ochsendorf demonstrated in his lecture with the help of Chikara Inamura, such a “lineage” is visible in 19th-20th century Japanese structural engineering:
