Conference dinner at the Toshi Center Hotel

The First International Conference on Concrete Sustainability took place at the Toshi Center Hotel in Tokyo from May 27 to 29, 2013. This conference was organized by the Japan Concrete Institute (JCI) and co-organized by fib, ACI and RILEM. Two hundred and forty five people from 36 countries and regions registered for the conference. Four keynote, eight lead, and 158 general papers were presented. In light of the fact that this was the first international conference that focused on concrete sustainability, it can be said that the conference was successful. From fib, the current president Gordon Clark, deputy president Harald Müller, and the immediate past president György L. Balázs attended. The conference began with the opening and plenary sessions on the morning of May 27. Koji Sakai, chairman of the ICCS13 organizing committee and local steering committee, delivered the opening ad-

dress and emphasized the necessity to change the framework of concrete technologies and systems based on a sustainability point of view. Following the opening address, Taketo Uomoto gave his welcome speech as President of JCI. After the opening session, the following four keynote addresses were given in the plenary session: – “Importance of maintenance for sustainable concrete structures” (Taketo Uomoto, Public Works Research Institute, JCI President) – “Challenges for structural concrete into the future” (Gordon Clark, Ramboll, fib President) – “Concrete sustainability and resilience: institutionalizing principles, transforming practice” (Anne Ellis, AECOM, ACI President) – “RILEM activities in the field of sustainable construction and its future” (Nicolas Roussel, IFSTTAR, RILEM Honorary President)

All keynote speakers were present as the presidents of their respective organizations, JCI, fib, ACI and RILEM. As explained by Koji Sakai, we need to accelerate R&D for concrete sustainability. The president of these organizations can help the concrete industry move towards this goal through their leadership. During the general sessions eight lead papers were presented. The speakers were Mette Glavind (Denmark), Julie Buffenbarger (USA), Doug Hooton (Canada), Adel Zaki (Canada), Harald Müller (Germany), György L. Balázs (Hungary), Nemkumar Banthia (Canada), and Dong-Uk Choi (Korea). All are leading researchers and engineers on the international level. The conference banquet was held on May 28, during which three awards were presented. Aruz Petcherdehoo received the Best Conference Paper Prize for the paper “Environmental Impacts due to Structural Concrete 14 (2013), No. 3

fib Commission 6, “Prefabrication”: background and current activities In the 1950s fib’s predecessors, CEB and FIP, both had an interest in prefabrication; as it was particularly linked to the recent prestressing technique, the Commission on Prefabrication was created within FIP in 1955. The commission has been continuing for now almost 60 years, contributing in particular to the CEB-FIP, and then fib, Model Codes for Concrete Structures. It is the only commission that has kept its original name from before the CEB-FIP merger and will continue to keep it in the upcoming restructuring of fib commissions and special activity groups. Commission 6 enjoys a privileged position, partly thanks to the support from industry, which participates in the activities through its experts. Professionals and academia are well represented too, giving opportunities for joint research projects. About forty members are currently active. Their well balanced interaction has been always friendly and fruitful, within the limits set by the volunteer work, compensated by their enthusiasm, and it is the basis of the success of the group, which gives to its members – and hopefully transmits to the community – more than what they contribute individually. Particularly important is the ommission’s close collaboration with the U.S. Precast/Prestressed Concrete Institute (PCI), which is ongoing since 2008. Started from a discussion on the different approaches to several issues, it developed beyond expectations, up to the collaboration on joint technical documents. These documents will be published soon and represent fully merged views from the experiences of both organizations. The PCI-C6 collaboration was initially approached as only one part of the Commission’s meeting agendas, but now is fully incorporated in all issues. Although the Commission’s members come from all continents, the core membership is

European; thus, collaborating with an institute that has a broad experience and influence in America widens its perspective and enhances its potential. Precast construction is continuously evolving to keep pace with market demands. The mission of Commission 6 is to enhance its progress, by stimulating, promoting and coordinating research internationally, and to disseminate this knowledge by means of publications, seminars, courses, and educational material. The Commission’s scope is well defined and encompasses several aspects that are directly related to precast concrete, like elements, connections, production, handling, assembling, dismantling, etc., as well as indirectly related, like materials technology, structural analysis, building physics, equipment, sustainable development, etc. Some issues that were initially addressed in prefabrication have an influence on all concrete structures. For instance, in precast structures, which are assembled piecewise, the study of problems such as design against accidental actions, robustness, and diaphragm function, led to concepts with generalized validity. Further, as they often have innovative features, precast elements need research to assess their performance and verify their safety. This is the case of prestressed hollow-core slabs without mild steel reinforcement, whose resistance to shear and torsion has been object of extensive experimental and theoretical investigation, leading to models proposed in FIP and fib Recommendations and later adopted in CEN Standards. Design assisted by testing has been also contributed by the Commission. Themes considered by C6 over the years have been: design concepts (specific to prefabrication), optimization of production, structural efficiency (for saving weight and room), particular performances (in

accidental actions, earthquakes, fire), best use of materials properties (HSC, HPC, SCC), flexibility in use (structures able to match particular requirements or changes of use of buildings), speed of construction, quality consciousness, durability, environmental friendliness (noise, dust and waste control), sustainability (saving materials, then energy and natural resources), life-cycle design (including possible recycle of materials, dismantling with or without reuse of elements, reuse of entire structures). The technical work is performed by appointed Task Groups and discussed in plenary sessions of the commission. Meetings take place regularly twice a year; they are organized by a commission member with the support of local bodies, last typically three days and include individual TG meetings, a technical visit and a plenary session. Often a seminar or a short course with local engineers is organized in conjunction with the meeting. Each TG’s work results in the publication of a bulletin, which transfers the specific knowledge to practical design and construction indications, while having often a pre-normative value, anticipating and helping Standards and Codes. Among them, a Handbook is going to be issued, addressed mainly to non-experts of prefabrication, updating a previous FIP one. After some 20 bulletins published within FIP, those published within fib are: – Bulletin 6: “Special design considerations for precast prestressed hollow core floors”. Guide to good practice, 2000. – Bulletin 19: “Precast concrete in mixed construction”. State-of-art report, 2002 - Bulletin 21: “Environmental issues in prefabrication”. State-of-art report, 2003

Further bulletins are currently under development by the following Task Groups: – TG 6.13, Quality control for precast concrete, convened by J. Fernandez Gomez – TG 6.14, Precast concrete towers for wind power generators, convened by V. Da Guia Lucio – TG 6.15, Sustainability of structures with precast elements, convened by D. Fernandez-Ordoñez – TG 6.16, Precast concrete bridge, convened by H. Corres Peiretti. Topics of interest for future work have been identified: e.g., maintenance, repair and retrofit, glossary, etc., and await volunteers to take them over. C6 members have also collaborated on bulletins drafted by other Commissions and SAGs, e.g. Bulletin 27, “Seismic design of precast concrete building structures”, State-of-art report, January 2004, and, above all, to the fib Model Code for Concrete Structures 2010. Furthermore, the convener of TG 6.16 is Hugo Corres Peiretti, a prominent specialist and member of Commission 1. For more than half a century Commission 6 has been contributing to the progress of structural concrete, mainly but not exclusively applicable to prefabrication. Now the need to update its tools has come to the fore. The commission is working on establishing its own website to assist internal communication and exchanges when elaborating documents. This should be also a powerful means for disseminating knowledge, downloading papers and holding forums. However, this involves issues of fees, copyright, sponsorship, etc., that need to be examined in the Commission and in fib Technical Council. Future activities and new ways of proceeding are a hot topic of discussion these days. Marco Menegotto

On 5 June 2013 a colloquium entitled ‘New Model Code for Concrete Structures’ was held in Brussels. The colloquium was organized by the Belgian Concrete Society, which is the national member group in fib, and by scientific coordinators Prof. Stijn Matthys of Ghent University and Prof. John Vantomme of the Royal Military Academy. The colloquium was well attended, with a balanced representation of industry, government and academia. In his welcome address Prof. Luc Taerwe, head of the fib Belgian delegation, introduced the objectives and current activities of fib, and the role of fib Belgium as a national member group. Prof. Joost Walraven, Honorary fib president and the convener of Special Activity Group 5, “New Model Code", gave a presentation entitled “Model Code 2010 for Concrete Structures”. He discussed the main trends in the new Model Code, looking into differences from the past, and highlighting various aspects including design verifications of limited states associated with durability, verifications assisted by numerical simulations, shear design using different levels of approximation, nonmetallic reinforcement and fibre reinforced concrete. In the “Advances in concrete and structures: report from fib Task Groups” session, current activities by Belgian fib members were reported. Prof. Stijn Matthys, convener of Task Group 9.3 on ‘FRP reinforcement’ gave an overview of the contributions of Ghent University to TG9.3, as well as SAG7 on ‘Actions and interventions upon existing structures’ and Commission 2 ‘Reliability assessment of concrete structures’. Prof. Lucie Vandewalle, of KU Leuven University and convener of Task Group 8.3 discussed the introduction of fiber reinforced concrete in

Sixth International Symposium on Strait Crossings the new fib Model Code. Furthermore, Ir. Jan Desmyter of the Belgian Building Research Institute presented on the work of Commission 3 on ‘Environmental aspects of design and construction’. The session was closed by Ir. Stef Maas of the Belgian Precast Concrete Industry Federation (FEBE) with a discussion on prefabrication (fib Commission 6), including the work of Task Group 6.1 on ‘Prestressed hollow core floors’ of which he is the convener. A session on “Advances in concrete and structures: the industrial perspective” allowed sponsor companies of fib Belgium to present recent challenges and advances on concrete design and construction, among which speakers Patriek Depuyt, Pieter Van der Zee, François Lepers and Jean Lansival of the respective companies Besix, Ergon, Gamaco/Freyssinet, Ronvaux and Nathalie Balfroid of the Belgian Cement Association FEBELCEM. The speakers addressed challenging concrete engineering projects in Belgium including the new Artevelde sports dome in Ghent, the fourth lock in Lanaye, residential buildings with long cantilevers in Temse, as well as international projects in the Netherlands, France, Poland and Saudi Arabia. Ir. Arnold Van Acker addressed the participants with his closing speech “Motivation to become a member of a fib Task Group”, in which he gave his personal view – based on a rich hands-on experience – of being an active member in fib task groups; and in which he encouraged participants to actively contribute in task groups and to benefit from that. At the end of the day Prof. Taerwe honored Arnold Van Acker for his lifetime achievements in this field. Stijn Matthys

From the 16th to the 19th of June nearly 250 experts from 27 countries were gathered in Bergen, Norway to attend the Sixth International Symposium on Strait Crossings with focus on Extreme Crossings and New Technologies. Some 100 contributions were presented covering the main symposium themes: bridges, tunnels, ferries and regional development. Straits and sounds, as well as inlets and fjords, are barriers for road and rail transport. These barriers can be overcome using fixed links or ferries. For crossings served by ferries there is often a strong wish for a fixed link replacement. At the symposium many outstanding strait crossings projects were reported from around the world, with the majority of presentations centered on the challenges associated with establishing a ferry-free connection on Coastal Highway Route E39 running on the west coast of Norway between the cities of Kristiansand and Trondheim. Crossing the remaining seven wide straits here served by ferries represent extreme challenges both in width and regarding wind and current conditions. Solutions presented for crossing the Sognefjord between Lavik and Oppedal where the fjord is 3.7 km wide and 1.3 km deep, involve suspension and floating bridges as well as submerged floating tunnels surpassing all known designs both in

length and structural concepts (video-animation: http://www.youtube.com/watch?v=L7en6etg2Mk& feature=youtu.be). In addition to the technical solutions the effects of fixed links on future regional development both socially and economically were also considered as well as developments regarding ferry design, propulsion and operations. Three technical visits were arranged on the last day. One to the Nordhordland Bridge north of Bergen, the longest end anchored floating bridge of its kind with a 1246 m long floating part connecting on to a 369 m long cable stayed bridge giving a total length of 1615 m. Another visit was to the Bjorøy tunnel, a subsea tunnel situated near Bergen and the third visit was to the nearly completed Hardanger Bridge crossing the Eidjord east of Bergen. The main span of this suspension bridge is 1310 m and total length is 1380 m. Previous symposiums have been held in Stavanger 1986, Trondheim 1990, Ålesund 1994, Bergen 2001 and Trondheim 2009. This edition was organized by the Norwegian Public Roads Administration in cooperation with Tekna – The Norwegian Society of Graduate Technical and Scientific Professionals.
