RILEM-fib MoC

On 2 September 2015 in Mel-bourne, Australia, a memorandum of cooperation (MoC) was signed by the fib and the Réunion internation-ale des laboratoires et experts des matériaux, systèmes de construction et ouvrages (RILEM) / International Union of Laboratories and Experts in Construction Materials, Systems and Structures.

RILEM advances scientific knowl-edge related to construction ma-terials, systems and structures and encourages the transfer and applica-tion of this knowledge worldwide.

Both the fib and RILEM have been members of the Liaison Committee for International Civil Engineer-ing Associations since 1958, when the venture was founded on a CEB initiative.

The signatories were fib President Harald S. Müller, RILEM Presi-dent Mark Alexander, fib Secretary General Petra Schumacher, RILEM Secretary General Pascale Ducor-net, fib Immediate Past President Gordon Clark and RILEM Develop-ment Advisory Committee Chair Roberto Torrent.

The signing of the memorandum of cooperation took place in the Ele-ment Room at Pullman Albert Park, the venue for the 27th Biennial Na-tional Conference of the Concrete Institute of Australia, in conjunction with the 69th RILEM Week Confer-ence.

One of the main goals of coopera-tion is the coordination of technical activities in the field of structural concrete between the two associa-tions, which could include having members of each organization par-ticipate in the committee activities of the other.

Members of both organizations will benefit directly from this agreement by being able to purchase the other organization’s publications at a dis-counted price.

Both organizations are convinced that greater productivity and ac-curacy in scientific output will be

achieved through their joint coop-eration.

of Tarmac Precast), Mark Magill (Creagh Concrete) and David Scott (Laing O’Rourke).

Dr Taylor presented advances in pretensioned long spans, mainly for bridge beams. He noted that except for the use of higher strength concrete, SCC and tendon strengths, technology has not changed very much in the past fifty years; how-ever, the efficiency of design has enabled spans of up to 45 metres. He showed examples of long-span beams from the UK and the Mid-dle East in addition to discussing the principles of joint-free integral bridges of up to 300 metres long.

On 23 September 2015, 105 del-egates attended a very successful evening organized by fibUK at the Institution of Structural Engineers, London. The theme, ‘Precast con-crete – a continuing evolution’, was very much a demonstration of the development of precast concrete buildings and bridges over the past seventy-five years.

The seminar was chaired by fib Commission 6 member Kim El-liott, who took the opportunity to highlight the role of fibUK, whose membership has increased from ten to twenty-six corporate and academ-ic members in the past five years and whose half-day seminars and evening meetings have become even more popular. Dr Elliott also spoke about the work of fib Commission 6 and the recent handbook for the planning and design of precast structures (fib Bulletin 74). This was followed by a personal world tour of precast concrete buildings in nine countries.

The evening’s speakers were How-ard Taylor (Consultant, formerly

Mr Magill as Engineering Manager and Senior Structural Designer with Creagh is at the forefront of current design in precast concrete elements, connections, frames, arches and so forth. Using the Manchester Metro-politan University (MMU) as a case study, he explained the role of digi-tal engineering between the design office and production shop, together with the harmonization of details on site. Two thousand two hundred and forty pieces were erected in just twenty weeks at MMU, including composite half-slabs (precast soffit, void formers and in-situ topping) up to 12 metres in span, shallow beams, tall columns and hidden connections. He also showcased reinforced, precast elliptical arches at Windsor Walk, London, with an average depth of 730 millimetres by a 1,500-millimetre-wide cross section, 16.2 metres in height, with a minimum radius of 4.4 metres, enveloping a four-storey, in-situ building beneath.

Mr Scott brought the evening to an excellent conclusion by noting that the past and the present of ‘evolu-tion’ had been covered and that his talk would be about concrete in the age of digital enlightenment. As Lead Structural Director for the Engineering Excellence Group at Laing O’Rourke, Mr Scott is well positioned to discuss R&D initia-tives, such as the so-called ‘mega plank’, a composite steel, precast floor slab with integrated services used in seven-storey buildings erected in seven weeks with a team

fib Secretary General Petra Schumacher will move back to her native Germany to take on new responsibilities in 2016.

After obtaining her PhD at Delft University of Technology under the supervision of Professor Joost Walraven, Dr Schumacher worked as a civil engineer for Shell in the Netherlands. She took on the role of fib Secretary General in Lausanne in January 2011.

She will be sorely missed by col-leagues and friends within the fib, who wish her all the best in her new endeavours.

Potential candidates for the position of fib Secretary General are invited to visit the website (fib-international.org) for a detailed job description and information on how to apply.

ICCRRR 2015

Departure of fib Secretary General Petra Schumacher

The Fourth International Confer-ence on Concrete Repair, Rehabili-tation and Retrofitting (ICCRRR 2015) was held in Leipzig, Germany, from 5 to 7 October.

The conference was a venture by researchers from the Material Sci-ence Group at Leipzig University, the Leipzig Institute for Materials Research and Testing (MFPA) in Germany and the South African Research Programme in Concrete Materials (based at the Universi-ties of Cape Town and the Witwa-tersrand).

fib TC Deputy Chair Frank Dehn and fib Head of Delegation for South Africa Hans Beushausen were among the ICCRRR organizers

of five workers, and composite hollow-core units connected to steel lattice beams for buildings of up to forty storeys high. Aiming for 70 per cent prefabrication, enabling 60 per cent reduction in site labour, the key features of this work are clash-free digital reinforcement and compo-nents for buildings, bridges, tram decks, water tanks and infrastruc-ture for the nuclear industry.

The discussion session focussed on the supply chain for precast con-crete in the UK and enquired how successful companies like Creagh and Laing O’Rourke were in win-ning contracts against steelwork and cast-in-situ methods. The chairman thanked the speakers and the organ-izers at fibUK and the Institution of Structural Engineers for the suc-cess of the event. More people had registered than could be seated in the room.

specifiers and researchers from around the world to share knowl-edge and experience on current developments. One hundred and eighty people attended.

A welcome reception was held at Moritzbastei on 4 October, and the gala dinner on 6 October at the con-ference venue, the Westin Leipzig Hotel.

Due to the success of the event, planning for ICCRRR 2018 has already started.

fib Bulletin 76

Benchmarking of deemed-to-satisfy provisions in standards: Durability of reinforced concrete structures exposed to chloridesState-of-the-art report. May 2015191 pages. ISBN 978-2-88394-116-8 Non-member price: CHF 140

Standards for specifying and ensur-ing the durability of new concrete structures are commonly of the prescriptive kind. fib Bulletin 76 ‘Benchmarking of deemed-to-satisfy provisions in standards: Durability of reinforced concrete structures exposed to chlorides’ presents the benchmarking of a number of rules for chloride-induced corrosion as given in national codes such as European, US and Australian stand-ards.

fib Bulletin 76 is the first bulletin to feature the new fib design.

This new benchmark determines the reliability ranges in the chloride-in-duced depassivation of rebar, if the deemed-to-satisfy rules of different countries are taken into considera-tion.

It does not only involve (probabilis-tic) calculations using input mainly

The reliability analyses are carried out using the probabilistic design approach for chloride-induced corrosion presented in fib Bulletin 34 ‘Model Code for Service Life De-sign’ (2006), the ‘fib Model Code for Concrete Structures 2010’ and ISO 16204:2012. The work compares the calculated reliability ranges thus determined with the target reliabili-ties proposed by current specifica-tions and, based on the comparison, offers a proposal for the improve-ment of deemed-to-satisfy rules and specifications.

fib Bulletin 76 presents and dis-cusses in detail the input data for the examined model parameters and offers an extensive annexe docu-menting the values of the individual parameters used in the analyses. It thus provides a reliable database for the performance-based probabilistic service-life design of concrete struc-tures exposed to chlorides, be they in the form of salt fog, sea water or de-icing salts.

At its meeting in Sydney in Au-gust 2015 the presidium agreed to establish a core group of members to prepare a detailed roadmap for the next generation of the fib Model Code for Concrete Structures 2010 (MC2010), the most advanced struc-tural concrete code available today.

The new initiative, to be entitled fib Model Code 2020, will be submitted to the technical council for approval and will be carried out under the direction of a new special activity group, which will be comprised of members from all of the fib’s existing commissions.

This new edition will update the ma-terial in MC2010 and will add data on existing structures.

Short notes

Hans-Ulrich Litzner – 70th birthday

The fib wishes Hans-Ulrich Litzner a very happy birthday.

Dr Litzner graduated in civil en-gineering from RWTH Aachen University, Germany, and obtained his PhD from the same institution. He subsequently worked for the Institute for Metallic Structures at the Swiss Federal Institute of Technology in Lausanne and later joined the German Concrete Society (Deutscher Beton- und Bautechnik-Verein) in Wiesbaden, where he was appointed Director in 1990 and Managing Director in 1995.

For more than two decades Dr Litzner played a central role in the development of national and international codes of practice. For instance, from 1990 to 2002 he was Chairman of CEN TC 250/SC 2, which prepares European Standards (EN) for the design and execution of concrete structures.

Dr Litzner was active in the CEB from 1979 onwards and became involved in the Model Code Revi-sion Group in charge of preparing the CEB-FIP Model Code 1990. He

George Somer-ville OBE FREng1934–2015

Engineering and was made Officer of the Order of the British Empire by her Majesty Queen Elizabeth in 1997. A fellow of both the Institu-tion of Structural Engineers and the Institution of Civil Engineers, he devoted his entire career to struc-tural concrete. He was a staunch supporter of both the CEB and FIP and latterly the fib.

Over the course of about 40 years George became Director of Research at the UK’s Cement & Concrete As-sociation (later

the British Cement Association, of which he was Director of Engineer-ing until his retirement in 1999). He made major contributions to the development of structural concrete, particularly through his work on national and international code committees, participation in interna-tional projects on durability, and the authorship of authoritative guidance documents.

George led the UK efforts in the early 1990s to improve the durabil-ity aspects of post-tensioned bridges and lectured around the world. His work on the durability of concrete structures provided important background to fib publications on grouting and post-tensioning, espe-cially in bridge design, and in 2008 he authored a book entitled ‘Man-agement of Deteriorating Concrete Structures’. He was Emeritus Profes-sor at Imperial College and served as Chairman of the Board of the UK certification authority for reinforc-ing steels (CARES) from 2001 until 2010.

George died on 4 September 2015 after a long illness. He leaves his wife, Kay, two sons, Neil and Alan, and three grandchildren.

With a strong vision for the develop-ment of structural engineering in concrete, Ton was convinced from the start that concrete technology and concrete design and construc-tion should be treated as an integral part of engineering applications. He held that concrete structures should not be subdivided into separate fields, such as reinforced, prestressed and partially prestressed concrete, or external prestressing and prestressing with unbonded ten-dons, but that an integral approach should be standard. In his lectures, courses and presentations he always emphasized that good design be pre-ceded by understanding and realistic modelling. For him, building codes were supposed to be no more than an aid to design.

Ton was an inspiring teacher and speaker, illustrating his ideas with numerous practical examples, most of which came from his own experi-ence.

From 1976 to 1983 Ton was Chair-man of the Concrete Association of the Netherlands. His book ‘Theory and Practice of Prestressed Con-crete’ became a standard manual and he held honorary doctorates from the University of Stuttgart and KU Leuven. In 1984 he obtained the FIP Medal of Merit.

Ton passed away on 24 September at the age of 92 but will live on in the memory of his many friends and colleagues.

Joost Walravenfib Honorary President

was elected to the CEB Admin-istrative Council in 1993 and was appointed Honor-ary Treasurer in 1997. He was a member of the

fib Presidium from 1998 to 2006 and Honorary Treasurer from 2007 to December 2014. In 2010 he was awarded honorary membership at the fib Congress in Washington, DC.

After obtaining his PhD from Delft University of Technology, Netherlands, in 1947, Professor A.S.G. ‘Ton’ Bruggeling worked as a structural engineer for the State Department of Buildings. In 1951 he became Deputy Director and subsequently Director of the precast concrete firm Spanbeton. In 1966 he obtained the directorship of the consulting office ABT in Arnhem and in 1969, a professorship in con-crete structures at Delft University of Technology.

Ton Bruggeling was a longtime and active mem-ber of the FIP, CEB and fib. He chaired FIP Commission 2 ‘Prestressing Steel

and Systems’ and was instrumental in the development of the FIP ‘Rec-ommendations for the Approval and Acceptance of Steels for Prestress-ing Tendons’, the basis for the EOTA guidelines on post-tensioning sys-tems. He was also a member of FIP Commission ‘Prefabrication’ and coauthored several other reports. In the fib he convened Task Group 9.4 ‘Bond of Prestressing Materials and Tendons’.
