Architects and engineers are often dealing with the steering of form, but the connectivity (or topology) of a structural pattern is equally important. We propose "topology finding" by analogy with "form finding" and apply it to shell structures.

Structural optimisation is a powerful tool that is rarely used in architecture. There are many reasons why, but one might be that structurally optimal structures obtained with usual computational techniques are not constructible and must be post-rationalised. We just published an article that aims at finding structurally optimal shapes for shell structures which remain constructible. The proposed method is benchmarked on several tests and compared with a common approach found in the literature.

Professor Hoshyar Nooshin was awarded with the Torroja medal, the most prestigious prize awarded by the International Association for Shell and Spatial Structures. He is a pioneer of parametric structural design, with his work on configuration processing and formex algebra. Congratulations! He was also Olivier Baverel's PhD advisor in Surrey, where he ran the Space Structures Lab for many years.

The IASS was founded by Eduardo Torroja. In comemoration, the Association awards the Eduardo Torroja Medal in its highest recognition of outstanding and distinguished contributions to design, construction or research of shell and/or spatial structures.

This year's Medalist and one of our plenary speakers is Professor Hoshyar Nooshin from Tehran, Iran. His main area of research at the University of Surrey is computer-aided design of spatial structures. He established the concepts of formex algebra, formex configuration processing, and the associated programming language Formian. Just as algebra takes a variable x and transforms it through a series of functions, formex algebra takes a configuration, a geometric composition of points, lines, and surfaces such as a space frame structure, and allows designers to manipulate it to explore and invent forms. Discover tutorials and more here: http://www.formexia.com/page/Home/?lang=en

Nooshin has also been a dedicated and active member of International Association for Shell and Spatial Structures. He was the Chief Editor of the International Journal of Space Structures for 20 years. Also, he was a member of the executive council of the International Association for Shell and Spatial Structures (IASS), as well as a member of the Advisory Board of this association for a number of years.

Some of my reactions to Professor David Billington passing away. I warmly recommend reading the Tower and the Bridge, his most famous work.

Thinkshell

David Bilington passed away last month. He is known for being the author of the Tower and the Bridge, one of the most important books on structural engineering, which is in our ideal library on engineering. It's probably the book that was mentioned the most by my professors at MIT (John Ochsendorf, Jerry Connor, Caitlin Mueller), and I was much intrigued since I never heard of it in France.

I first read the Tower and the Bridge at age 23 while writing my master thesis at MIT, and read it once again at age 26 during my (no so short) bibliography on thin shells for my PhD. Like in many great books, you find something different each time.

The first time, I was enthusiastic about the epic story of engineering, the adventurous mind of great designers like Candela, Freyssinet, Nervi... The book did a great job to make those names famous, and to show the role of creativity in structural design, a topic that will be explored in the next IASS Symposium in Boston (an association of which Billington was honorary member).

The second time, I was struck by the fact that those 'structural artists' were also builders, and had to face the consequence of their design decision on the construction field (actually they produced their most significant work of structural art when they were under pressure). I found here some resonances with our research on the topic of 'construction-aware structural design' at the Navier Lab, and with my growing experience of structural engineering. I also noticed that many great names started to design their masterpieces with a long experience behind them (Freyssinet, Nervi), which is a humbling thought for a young engineer.

There are countless quotes from the Tower and the Bridge and other papers written by Billington. Here is an interesting one that illustrates his delightful writing:

''It so happens that the work which is likely to be our most durable monument, and to convey some knowledge of us to the most remote posterity, is a work of bare utility; not a shrine, not a fortress, not a palace, but a bridge.‎''

It is a pleasure to see that our work at thin[k]shell on composites gridshells is spreading and that others continue to explore new ways to extend this constructive technique and to make it affordable for as many people as possible. Note that the grid pattern is obtained thanks to a rhino plug-in of our own implementing the compass method, while the form-finding relies on Kangaroo2 and the structural analysis on Sofistik.

Description
Les structures porteuses sont responsables d'environ 70% de l'énergie grise demandée par nos bâtiments et de la majeure partie des déchets produits en termes de poids et volume. À ce titre, elles constituent une opportunité unique pour amoindrir l'impact environnemental du secteur de la construction. Différentes actions, réunies sous le terme d'économie circulaire, existent pour diminuer cet impact: réduire la demande en ressources, réparer, réutiliser, recycler et biodégrader. Outre un basculement économique, ces actions requièrent de nouvelles technologies et de nouveaux outils de conception.

Cette présentation contextualise le propos et donne un aperçu de trois recherches développées au Laboratoire d'Exploration Structurale (EPFL) dans ce domaine: stock-based structural optimization, structural design for reassembly, computerized equilibrium design.

Book review: 'Un amour sans limites' by Eugène Freyssinet, part of our ideal library

Eugène Freyssinet is known as the inventor of pre-stressed concrete, and as a successful entrepreneur (the company Freyssinet is still a flagship of french pre-stress industry, and holds several world records for cable-stayed bridges). But the man remains quite of a mystery: few books allow us to understand his vision of the art of building (with the exception of 'The Tower and the Bridge' by David Billington).

The book 'un amour sans limites" (an endless love) uncovers his personality and dedication for his art. In his own words, Freyssinet describes several of his invention (slip forming for thin shells, decentring with jacks, quick setting cement, concrete vibration, ribbed shells) and his investigation on creep of concrete that were necessary for the proper definition of pre-stress. Although he got strong scientific background and degrees from l'Ecole Polytechnique and l'Ecole Nationale des Ponts et Chaussées (where he first got the idea of pre-stress), Freyssinet saw himself as a manual worker who solved practical problems. His concepts for pre-stress were not in agreement with building codes from 1906, but he opposed practical experience to a priori mathematical modelling. This allowed him to propose one of the most important innovations of the twentieth century. He doesn't deny the importance of building codes, with two conditions:

1. It should be based on practical full-scale experiments
2. As a consequence, a building code should not apply to something that hasn't been built before.

The love for his work is clear throughout the book. At age 50, he abandoned a position as a technical director of a construction firm and invested his money to develop pre-stress concrete. There a couple of illuminating comments on the construction of unreinforced concrete bridges in the 1920's (where he discovered long term deformations of concrete as one the bridges deformed by 5 inches several months after being completed).

It is somehow hard to find, and it wasn't translated in english. If you have the chance to read it, don't hesitate!

On Wednesday 24, we will have the pleasure to welcome Dr. Christopher Robeller, now Junior Professor at Kaiserslautern University. Christopher Robeller completed his PhD at the iBois Lab from EPFL. Find out more on his webpage http://www.robeller.net/.

Here is the description of the presentation:
---------------------------------------------------------------------
Integrally Attached Timber Plate Structures: A Digital Resurgence of Traditional Joining Methods:

Integral Attachment, the joining of parts through form rather than additional fasteners is the oldest known joining technique. Such joints were common in traditional carpentry until the industrialisation. Early machine technology was not capable of producing these elaborate joints efficiently, instead they were replaced with mass-produced metal fasteners.

Only recently, advanced Digital Fabrication technology has become capable of producing complex-shaped joints efficiently. Automatic joinery machines have brought back integral joints due to their locator features, helping to simplify the transport and on-site assembly of prefabricated timber structures. Integral attachment takes advantage of the easy, low-energy machining of wood, as well as its favourable weight-to-strength ratio – making it an ideal material for the prefabricated structures of the future. It combines high-tech prefabrication with a rapid, simple and precise on-site assembly.
However, while the industry has used these methods primarily for an increased automation and improvement of existing building typologies, the methods bear great potential for entirely new types of sustainable, lightweight timber structures. The development of algorithmic design tools allows architects to tap directly into the resources of rapidly advancing robotic fabrication technology, and opens up new possibilities for the “design of assembly”. Computational design enables features such as self-locking joint geometries and interlocking assembly sequences, which are new to architecture, but common in other industry sectors.

The accomplishments of D2P (Design to Production) are a great example of how digitalization of the construction industry might change the way we construct our buildings. Check out this interview of Fabian Scheuer, who expects construction to become a real industry. In his words:

'“Industry” means having standardized processes and workflows in place and deliver reliable quality.'

Their work is truly inspirational, including for our timber pavilion prototype built last year: Tristan Gobin worked with D2P some years ago!

The good thing about engineering is that you might break big things! We had a go with the timber gridshell we constructed with our students in 2016 and were very excited to do a full-scale test. Done at École nationale des ponts et chaussées with our colleagues from ENSG Géomatique. Notice that the gridshell first collapses because of instabilities and not material...

Some people think that automation will bring back the notion of master builders. Parametric design tools offer indeed a new opportunity to integrate construction constraints from conceptual design stages. But there is a long way to go from drawings to robotised fabrication. Our recent experiments on digital fabrication tend to show that the gap between detailing and conceptual design stages gets thinner, but do all architects have this flexibility in real-life projects?

The change of paradigm promised by this article will require research and education. There are so many things to do for Design by Data and École nationale des ponts et chaussées graduates and researchers!

Some members of our lab work actively on origami. Find out why this matters with this video on Robert Lang a pioneer of the art of origami.

Robert Lang is a physicist who worked at NASA studying lasers and has 46 patents on optoelectronics to his name. However, that's not what he's best known for now: he's a legend in the world of origami. His intricate designs are second to none, and they actually have applications back in engineering.
