The Third International fib Congress and Exhibition (incorporating the PCI Annual Convention and Bridge Conference) took place from 29 May to 2 June 2010 and was an undisputed success, with more than 1,700 attendees, including 700 industry professionals from 56 countries around the world.

This unprecedented joint event took place at the Gaylord National Resort near Washington, D.C., and included over 125 educational sessions and hundreds of technical papers. Educational sessions covered tracks on architectural topics, research, sustainability, operations, business development, and executive subjects.

The Congress participants were welcomed at a reception held on Saturday evening, 29 May, in the Gaylord's vast exhibit hall, where they had ample room to mingle and get a first look at the over 90 exhibitors who would be on display during the following three days. At the opening ceremony breakfast on Sunday morning, 30 May, the Congress participants were extended a warm welcome by PCI President Jim Toscas and fib President Michael Fardis. They pointed out the excellent relationship and collaboration between PCI and fib, both in general and for the organization of the Congress, remarked on the notably high number of submitted papers, and on the unique nature of the joint event. PCI Chairman of the Board James Sorensen then took the podium and offered reflections on the role of PCI in the U.S. concrete industry.

During the awards portion of the ceremony, PCI President James G. Toscas, P.E., presented the PCI Fellows, Medal of Honor, Distinguished Educator, and Young Educator awards, and announced the 2010–2011 Leadership PCI Class. fib President Michael Fardis then presented the Freyssinet Medals for outstanding technical contributions in the field of structural concrete to Nigel Priestley of New Zealand and Jiri Strasky of the Czech Republic (see report on page 169). fib Honorary President Hans-Rudolf Ganz followed with the presentation of the 2010 fib Awards for Outstanding Concrete Structures (for details, see the June 2010 issue of fib-news). The ceremony then concluded with a keynote address by Jim Hartzfeld on “How to be more sustainable in your business”.

This impressive opening was followed by a full and varied technical program, which included the presentation of hundreds of peer-reviewed technical papers, including 53 papers on building systems, 160 papers on engineering and design, 160 on bridges and transportation, 86 papers on materials, and 25 papers on ultra-high-performance concrete. In addition, three sessions were reserved for reports by fib Commissions, and two for presentations by National Members. The delegations from Australia, the Czech Republic, Denmark, France, Germany, Hungary, India, Italy, Japan, Portugal, Slovakia, Spain and Switzerland had all published reports as books or CDs that were distributed to the Congress participants free of charge.

One of the highlights of the technical program took place on the last day of the Congress, with the presentation of the first complete draft of the 2010 fib Model Code for concrete structures (published as fib Bulletins 55 and 56; see the June 2010 issue of fib-news, pp 112-113) by Joost Walraven and several members of fib Special Activity Group 5, who have been developing and drafting the new Model Code since 2002.

The Congress concluded with a look back on the highlights of the event by fib and PCI Presidents Michael Fardis and Jim Toscas, presentations on upcoming fib events (the 2011 symposium in Prague, Czech Republic, and the 2014 Congress in Mumbai, India), and the traditional handing over of the Congress bell to the organizers of the 2014 Congress, represented by the Head of the Indian National Delegation, C.R. Alimchandani.

Social programs for the event included a memorable dinner cruise on the Potomac River and post-Congress tours of the nearby precast plants of Smith-Midland Corporation and The Shockey Precast Group.

The Congress program included meetings of fib Commissions, Task Groups, Special Activity Groups, the Technical Council and General Assembly, in parallel with PCI committee and council meetings. The fib Technical Council meeting included the usual Commission activity reports, as well as a brief presentation on the first draft of the 2010 Model Code and discussion of the review and approval process that will be followed in 2011 prior to the publication of the definitive version of the fib Model Code.

Elections were held by secret ballot during the General Assembly, and the following officers were elected:

• President, 1st January 2011 - 31 December 2012: György L. Balázs (Hungary)

• Deputy-President, 1st January 2011 - 31 December 2012: Gordon Clark (United Kingdom)

• Four elected Presidium Members, 1st January 2011 - 31 December 2014: Hugo Corres (Spain), Harald Müller (Germany), Tor Ole Olsen (Norway), Jun Yamazaki (Japan)

As the Honorary Treasurer for 1st January 2011 - 31 December 2014, Hans-Ulrich Litzner was re-elected. Furthermore, the GA unanimously approved Honorary Life Memberships in fib for Hans-Ulrich Litzner and Jun Yamazaki (as reported on page 170).

Awarded every four years at the occasion of an fib Congress, the Freyssinet Medal is the highest distinction awarded by fib. It is given “in recognition of outstanding technical contributions in the field of structural concrete”, and is a continuation of the Freyssinet Medals awarded by fib's predecessor organization, FIP (Fédération Internationale de la Précontrainte), since 1970.

The two 2010 Freyssinet Medals were awarded by fib President Michael N. Fardis on 30 May 2010 to Dr. Nigel Priestley (New Zealand) and Dr. Jiri Strasky (Czech Republic), during the opening ceremony of the Third fib Congress and Exhibition (see previous article).

Nigel Priestley received his doctorate from the University of Canterbury, New Zealand, in 1967. He is Emeritus Professor of Structural Engineering at the University of California at San Diego, Emeritus codirector of the Rose School (Pavia, Italy), and also works as a consulting structural engineer. His research focuses on the seismic design of concrete and masonry structures, and on seismic design philosophy. He was coordinator of the PRESSS (Precast Seismic Structural Systems) Research program (1991–1999) for the development of recommendations for the seismic design of buildings constructed of precast concrete. The project culminated with the construction of a large-scale five-storey precast concrete building that was tested under simulated seismic loading.

Dr. Priestley's consulting work involves design, analysis or checking of seismic performance of new and existing structures. He has participated in, and coauthored reports for, numerous post-earthquake reconnaissance teams, including Chile (1985), Whittier (1987), Costa Rica (1990), Northridge (1994), and Kobe (1995). He was the leader of the seismic checking team for the Rion-Antirion Bridge, Greece, and was the co-concept designer for the repair, retrofit, and upgrading to 100% increase in seismic capacity of the Bolu Viaduct in Turkey (Duzce earthquake, 1999).

Dr. Priestley has published more than 650 books, technical papers and reports, mainly related to seismic design. He has received more than 30 international awards for his research. He is currently a member of fib Commission 7, Seismic design.

Jiri Strasky obtained his doctorate in 1981 from the Brno University of Technology, Czechoslovakia. He began his career with Dopravni Stavby Design and Construction Engineers, where he eventually became Chief Design Engineer and Vice-Manager of the Design Department. He spent three years with T.Y. Lin International (California, USA), as Project Manager or Engineer responsible for design/rehabilitation of suspension, cable-stayed and cantilever segmental bridges. Since 1991 he is the Technical Director of Strasky, Husty and Partners; since 1994 he is also Professor at the Technical University of Brno and works as a consulting engineer.

He specializes in concrete and steel bridge design and construction, with expertise in nearly all systems (suspension, stress-ribbon, cable-stayed, arch, cantilever, segmental, post-tensioned, precast, composite). He has developed new design and construction concepts and has experience with elastic and plastic design of bridges built in severe seismic areas of California, Oregon and Taiwan.

Dr. Strasky has published two books, contributed to six books and published over 100 technical papers. He has won numerous awards for his design work, including the 2010 fib Award for Outstanding Concrete Structures for the Svratka River Pedestrian Bridge and the 1994 FIP Award for Outstanding Concrete Structure for the footbridge over the Vranov reservoir both in the Czech Republic, as well as several achievement awards, including the fib Medal of Merit (1999). He is currently a member of fib Commission 1, Structures.

Honorary life memberships are given by the fib General Assembly in recognition of significant personal contributions to the work of fib. At the Washington 2010 General Assembly, honorary memberships were bestowed on Hans Ulrich Litzner (Germany) and Jun Yamazaki (Japan).

fib Honorary Memberships continue the traditions established by its predecessors CEB and FIP since 1970. For further information on fib awards and honors, see www.fib-international.org/about/awards.

Recent advances in cementitious material and chemical admixture technology, as well as the growing use of recycled materials have supported the increasing use of modern types of concrete that are not covered in existing codes and specifications and which are tailor-made for a specific application or project.

Traditional prescriptive requirements for constituent materials, limiting water/binder ratios and cement contents are often not applicable for modern construction. The prescriptive design philosophy is largely based on the (often misleading) assumption that different concretes with similar mix proportions result in similar performance. With this approach, the combined influences of constituent material selection, construction procedures and ambient environmental conditions cannot adequately be accounted for.

In contrast, performance-based specifications relate to certain performance criteria that can be defined for a particular application. As such, performance-based specifications make demands on particular fresh or hardened concrete properties rather than on the concrete's composition. Performance-based design and specification therefore include the testing of relevant concrete properties and the evaluation of test results based on agreed conformity requirements.

With the advancement of testing methods for concrete, performance-based design and specification of concrete and concrete structures is possible and already applied in practice. The most widely accepted performance-based design approach is for compressive strength, which has been used for more than a century. For many applications, however, compressive strength alone is not a sufficient performance indicator, as the relationship between compressive strength and other important properties may vary widely between different types of concrete. More recently, performance-based design approaches in combination with suitable test methods were developed for concrete durability and are already applied in practice in some countries. In addition to compressive strength and durability, other properties (e.g. elastic/plastic deformations, fresh concrete properties, thermal characteristics during and after hardening, strength development, ductility, crack resistance, etc) need to be considered.

fib Task Group 8.10 aims to present the state of the art on performance-based specification and testing methods applied to modern concrete structures around the world. Guidelines and recommendations for testing and specification methods, including relevant conformity criteria and limiting design values, will be developed and presented to industry. Furthermore, TG 8.10 aims to form a common base for the initiation of national and international collaborations and research projects leading to pre-normative or even normative specifications. An important underlying intention of TG 8.10 is close cooperation with RILEM as an organization and with relevant RILEM Technical Committees, in order to successfully cover the combined fields of concrete material technology and structural engineering.

The conveners of TG 8.10 are Prof. Frank Dehn, MFPA Leipzig GmbH, Germany, and Dr. Hans Beushausen, University of Cape Town (UCT), South Africa.

The anticipated scope of TG 8.10 will combine the fields of concrete material technology, structural engineering and testing technology (non-destructive and destructive testing). TG 8.10 intends to cover all relevant concrete material properties for which performance-based specifications need to be developed to allow for rational application of modern concrete technology.

TG 8.10 is targeting professionals involved in the fields of structural engineering, concrete materials technology and testing technology. One particular intention is to invite members from RILEM to contribute in order to combine the expertise of the two organizations. The suggested size of the group is about 40 members.

The estimated duration of fib Task Group 8.10 is four years, during which the work will be subdivided into three phases:

• Phase 1 (July - December 2010): Orientation, invitation of members

• Phase 2 (January 2011 - December 2012)

  • Preparation of a State of the Art Review on performance based specification and testing methods

  • March 2011: First fib Workshop on performance based specifications for concrete structures

• Phase 3 (January 2013 - June 2014)

  • Preparation of concrete technological and structural design recommendations

  • June 2014: Presentation of a pre-normative document that can be included in codes and standards

Meetings are planned to be held yearly or half-yearly. Additional meetings may be arranged for Working Parties.

The workshop will take place on 24–25 March 2011 in Leipzig, Germany. A public announcement and call for papers will be made in August 2010. The workshop should have a maximum of 100 participants and presentation between 40–50 peer-reviewed papers. The Scientific Review Committee for the papers will consist of the Task Group members.

The work of TG 8.10 is to be carried out in close cooperation between members of fib and RILEM. Relevant existing RILEM Technical Committees (for example, TC 230 PSC - Performance-based Specification and Control of Concrete Durability) will be approached in order to find a basis for collaboration. State-of-the-Art reports of concluded RILEM TCs will provide a useful source of information and where needed, members of such concluded TCs may be approached for further discussion. In addition, the work of fib TG 8.10 is expected to yield research needs and research topics. Here, it would be useful if the identification of research needs resulted in the creation of new RILEM TCs.

• Provision of concrete technological background and development of practical questions

• Evaluation of existing or new test methods for performance-based assessment of concrete

• Assessment and/or development of principles for performance-based specifications and compliance control

• Development of (new) design concepts and models for performance-based concretes and concrete structures and transfer of the concepts into practice

Persons interested in getting involved in the work of fib Task Group 8.10 and/or in participating in the Leipzig workshop can contact the conveners Frank Dehn (dehn@mfpa-leipzig.de) or Hans-Dieter Beushausen (iccrrr@eng.uct.ac.za).

The V International Precast Seminar, was held April 29, 2010 in São Paulo, Brazil. Organized by ABCIC (Brazilian Precast Association), it received moral support from fib and also from national associations. There were more than 150 attendees, including academics, industry professionals, architects and design engineers. There was emphasis on architecture, precast housing, infrastructure and sustainability.

The construction boom that began in Brazil a few years ago is growing by the year. The 2014 soccer World Cup tournament and the 2016 Olympic Games are approaching and the upcoming construction of new sport stadiums and the upgrading of existing sports facilities, large infrastructural projects, enlargement of airports, implantation of high-speed trains, hotel, etc., are increasing the demand for precast building systems. In addition, the development program of Brazilian government requires speed of construction, high quality, low maintenance and controlled costs.

fib Presidium member Hugo Corres Peiretti presented the special requirements and challenge for using prefabrication in high speed railway bridges. David Férnandez–Ordónez (Convener of fib Task Group 6.7, Affordable housing), presented prefabrication for low cost or affordable housing. Brazilian architect Sidônio Porto talked about their projects and use of precast concrete since 1966. Sérgio Coelho (architect) presented the project for the Cuiabá stadium in mixed construction with precast concrete, part of the World Cup 2014 infrastructure. Sérgio Leusin (Professor at the University Federal of Rio de Janeiro) presented the recent standard approved in Brazil for modular coordination and Roberto Bauer (Civil engineer and president of Falcão Bauer Institute) discussed precast construction and sustainability.

Brazil became a statutory member of fib in 2008. ABCIC, represented by Marcelo Ferreira and Íria Lícia Oliva Doniak (both of whom are members of fib commission 6, prefabrication), together with ABECE (Brazilian Consultancy and Structural design Association) constitute the Brazilian National Group.

Prof. Kryvosheyev has had a long and illustrious career at NIISK in Kiev, where he began in engineering and scientific positions in 1960, and of which he became director in 1992. Throughout the years he has been a leader and innovator in the Ukrainian building industry, and has guided the development of NIISK as an important research centre with regional departments throughout the country.

His achievements include the construction of a number of modern multi-storied buildings in Ukraine, and the renovation and restoration of important Ukrainian national monuments.

As head of the Ukrainian consortium he played an important role in the study of the Chernobyl nuclear power plant containment problem, and the development of the new confinement system to replace the one built in 1986.

Prof. Kryvosheyev was the Scientific Secretary of the Ukrainian Department of the Soviet FIP Group from 1965 to 1980. From 1981 he was the Deputy Head of the Ukrainian Dept., and ten years later became Head of the Department. In 1996 Ukraine joined FIP as independent state, with Prof. Kryvosheyev as Head of the Ukrainian Group, a position he has continued in fib since the CEB-FIP merger in 1998.

In 2007 he was awarded the fib Medal of Merit, in recognition of his outstanding contributions to the field of concrete construction and to fib.

Our best wishes go to Prof. Kryvosheyev for continued success and good health for many years to come.

Prof. Max Reiss passed away on May 2, 2010, in Haifa, Israel at the age of 91.

He joined the faculty of Civil Engineering, Technion-Israel Institute of Technology, in 1956, after some 13 years of practice as a senior designer with expertise in reinforced concrete structures in general and special structures (spatial structures, silos, industrial plants, etc.) in particular. As a senior professor of structural engineering he promoted study and research in reinforced concrete, edited textbooks and made a profound impact on the Israeli reinforced concrete code.

For many years he served as the Israeli delegate for CEB, as well as on numerous national committees. He strongly influenced the Israeli Structural Engineering community, and will be remembered for many years to come, by his many colleagues and past students.
