Organiser's Message

, France, will host the 40th IABSE Symposium with the main theme of “Tomorrow’s Megastructures”. Popularised in the 1960s as an architectural concept, a megastructure is referring to a very large manmade object, though the limits of precisely how large this is, may vary considerably. The term could be applied to any especially large or tall building, but also to enormous self-supporting artificial constructions.

Megastructures represent the most ambitious and spectacular constructions in the world which are all incredible technological achievements of great human adventures. As the Jules Verne’s birthplace (who wrote many adventure novels, including a premonitory “Paris in the Twentieth Century” and the famous science fiction novel “From the Earth to the Moon”), Nantes is definitively the best place to address the following challenges:

   • Megastructures: a radical paradigm shift or simply a change of scale?
   Today’s and tomorrow’s megastructures and megaprojects
   New trends for innovations in the construction, the preservation, the exploitation and the upgrading of structures.

The organisers invite the world’s structural engineering community to share their experiences with today megastructures and to present their vision of tomorrow's megastructures and more broadly their prospect of future outstanding structures. Consultants, contractors, owners, researchers and practitioners will have the opportunity to exchange ideas and experiences on structural design, construction and maintenance issues.

The Symposium is organised by the French Group of IABSE and the French Association of Civil Engineering (AFGC). We have developed a remarkable list of keynote speakers, panellists and industry stakeholders. In addition, we have planned several workshops, technical tours, social events, a programme for accompanying persons, and event receptions, to provide the participants with an enriching and memorable experience.

This Symposium could not have been organised without the sustained effort of many persons. Of course, the authors, the committee members, and the reviewers are essential to the success of the Symposium. Especially, we would like to thank the members of the Scientific Committee for their efforts in handling of the papers and preparing an interesting technical program, and the members of the Local Organising Committee for concocting an amazing programme.

We hope that you will enjoy this Symposium, both for its scientific, technical and social aspects.
