24–25 October 2013: Vienna, Austria
On 24th and 25th of October 2013a two-days course entitled “ModelCode 2013 – Design of ConcreteStructures with Advanced Methods”took place in Vienna.
The course was organized by SmartMinerals GmbH (SMG) in coopera-tion with fib. Smart Minerals wasfounded as a spin-off by the ViennaUniversity of Technology and the ce-ment industry in January 2013. It isthe first cooperation between busi-ness and science in Austria. One ofits aims is to realize projects inwhich companies and scientific in-stitutes conduct research of interna-tionally competitive quality. Further-more, it has an accredited labora-tory for testing the materials con-crete, cement and minerals. Thecombination of concrete materialand construction research at that lo-cation provided an excellent basisfor teaching the fib Model Code2010 scientific models and applica-tions.
The seminar was well attended, withbalanced participation from thebuilding industry, civil engineers,building owners, construction com-panies and researchers.
The program was well planned withinteresting presentations, starting
12–13 September 2013: Buenos Aires,Argentina
This two-day course on the fib Mod-el Code for Concrete Structures2010 (MC2010) was co-organized byAAHES, Asociación Argentina delHormigón Estructural (ArgentineAssociation for Structural Concrete)as part of the events marking the50th Anniversary of its founding.
Participants came from BuenosAires as well as La Plata, Rosarioand other cities. Among them therewere engineers, professors, academymembers, researchers, designers, au-thorities and representatives of uni-versities, laboratories, professionalcolleges and engineering associa-tions, and also advanced engineer-ing students. fib Bulletins 65 and 66(Model Code – Final Draft, volumes1 and 2) were distributed to the par-ticipants on CD-ROM.
An evaluation by the participants af-ter the course gave completely posi-tive feedback. Answers revealed thegeneral interest in MC2010 and sat-isfaction about the way in which ithad been presented. Many of themalso highlighted the warm andfriendly atmosphere of the course.
The course was, at the same time,an opportunity to promote fib mem-bership in Argentina. To make gooduse of it, a leaflet was distributedamong the audience, with informa-tion about its activities, its commis-sions’ technical work, publications,
courses, awards, symposia and con-gresses, as well as a membership ap-plication. To support this effort, atthe end of the first day of lectures, ameeting was held between the fibrepresentatives and those of severalArgentine institution to exploretheir possible interest in joining fib,enhancing its Argentine NationalGroup, integrated since severalyears ago by AAHES. fib representa-tives and AAHES authorities partici-pating in the meeting are hopefulabout its results.
Finally, AAHES wants to express itssatisfaction and deep thanks for fib‘svery important participation andsupport of this interesting and fruit-ful course in Buenos Aires and forall of its collaboration in organizingand carrying it ahead.

merged in 1998 to create fib. Diffi-culties arose in the late 1990s, caus-ing the UK membership to be sus-pended for a year, but this becamean opportunity to create a newgroup, fibUK, in 2003. The group’smembership now includes consul-tant firms, a university, manufactur-ers, contractors, a certification au-thority and several associations. Thesecretariat of fibUK was held by theConcrete Society from 2003 to 2012when it was transferred to the Insti-tution of Structural Engineers.
The Institution of Structural Engi-neers regards hosting the fibUK sec-retariat as a very beneficial relation-ship, bringing many opportunitiesto add value to the Institution’s in-ternational community of 27,000members through collaborationwith fib members.
Within the UK, fibUK supports itsmembers in understanding andsharing developments in the work
of fib, disseminates fib informationand publications amongst members,and encourage closer links betweenindustry and academia. On an inter-national level it strives to positivelyinfluence and promote the work offib and foster coordinated participa-tion from UK in fib commissionsand task groups, and support inter-national networking.
The organisation of technical meet-ings and seminars is an importantpart of fibUK’s mission. In recentyears these have included:
– The first fibUK academic forumwas held on 16th May 2011 andbrought together representativesfrom leading universities, designers,contractors, product and materialsuppliers (see report published inthe September 2011 issue of fib-news, http://www.fib-international.org/fib_news_sept11.pdf)
– fibUK Technical Meeting on29 November 2012. This inauguraljoint meeting of fibUK and The In-stitution of Structural Engineerswas held to recognise the contribu-tions of Professor Andrew Beeby(see http://www.fib-international.org/fib_news_march13.pdf)
– Evening technical meeting basedon case studies demonstrating howfib bulletins can help solve engi-neering design issues on 11 April2013 (see http://www.fib-interna-tional.org/fib_news_june13.pdf)
– Most recently, a half-day seminarwas held on 6 November 2013, thefirst of an annual series entitled "De-velopments in Structural Concrete".This event marks the one-year an-niversary since the Institution ofStructural Engineers took over thesecretariat of fibUK.

After the successful workshops inLeipzig (2009) and Delft (2011), the3rd International Workshop onConcrete Spalling due to Fire Expo-sure was held in Paris from 25 to 27September 2013. This event was co-organized by CSTB and INSA deRennes and supported by fib andRILEM. The workshop was attend-ed by over 90 participants from 20countries. The technical programfeatured 33 oral presentations andseven posters with short oral presen-tations. The proceedings are avail-able online on the RILEM andMATEC websites.
Fire scenarios have demonstratedthat spalling of concrete can haveserious structural and economicconsequences and should be takeninto account when designing con-crete structures against fire. Devel-opments in concrete mix designhave led to new types of concretesuch as high strength, ultra-highstrength and self-compacting con-crete – which, despite an increasedstructural performance, have alsoshown a different sensitivity tospalling due to fire exposure. How-ever, this sensitivity to spalling ofconcrete as a structural material isso far not fully understood. More re-search is needed to understand themechanisms governing spalling ofconcrete in order to be able to quan-tify the risk as well as the conse-quences of spalling in a given firesituation.
Contributions addressed the under-standing of underlying processes,key properties and global behaviourof spalling under various conditions.It was very encouraging to see thevery high quality work presented bymany PhD students. We congratu-late Kevin Mueller from Universityof Notre Dame, USA, on his student
award for his presentation entitled“Design and Performance of a Skid-Mounted Portable CompartmentFire Gas Furnace and MonitoringSystem”.
The workshop was dedicated to thememory of Pr. Ulrich Schneider.Prof. Ulrich Diederichs, his longtimecolleague and friend, presented thehighlights of his distinguished careerand life.
The next workshop will be orga-nized in Leipzig by MFPA and DelftUniversity of Technology in October2015 in conjunction with the 4th In-ternational Conference on ConcreteRepair, Rehabilition and Retro-fitting.

3rd International Workshop on Concrete Spalling
Four years after the first fib-AFGCinternational symposium on Ultra-high Performance Fibre-ReinforcedConcrete (Designing and Buildingwith UHPFRC), over 330 partici-pants gathered again in Marseille,France, for the event’s second edi-tion, which took place in the justcompleted MuCEM, the outstandingUHPFRC architectural manifestodesigned by R. Ricciotti.
The updated experience in designingand building with UHPFRC was il-lustrated by 81 contributions from15 countries, collected in theRILEM PRO87 proceedings. The2013 revised edition of AFGC rec-ommendations on UHPFRC was al-so distributed to the participantsand can be ordered from AFGC(www.afgc.asso.fr).
Outstanding UHPFRC achievementsin Japan, France and Europe werepresented as well as many applica-tions in civil structures protection,
new bridges (Korea, France), bridgeretrofitting (USA, Canada, France,Switzerland) and buildings façadesand components. Experience on theeffective on-site durability of UH-PFRC was presented, which couldfavour further application in severe-ly exposed structures. Large-scaleexperiments help documenting theeffective UHPRC contribution tocomposite structures either withsteel, wood or reinforced concrete.The appropriate characterization ofUHPFRC post-cracking tensile ca-pacity and structural ductility hasbeen exemplified so that safe provi-sions can be assessed and further de-veloped, as has been done with theAFGC Recommendations, presentlyin accordance with Eurocode 2 de-sign standard.
UHPFRC producers have to face agrowing demand in façade compo-nents of buildings due to the demon-strated architectural and structuralversatility. The innovative character

fib Bulletin 69 illustrates and com-pares major buildings seismic codesapplied in different countries, name-ly U.S., Japan, New Zealand, Eu-rope, Canada, Chile and Mexico.
The first chapter gives a comprehen-sive summary of the major codes.Each code is presented according toa common framework: an introduc-tion section; a section on demand,which specifes the seismic design ac-tions and associated criteria of eachcode for areas of different seismicityand for structures with different duc-tility properties/require-ments; and athird section describing the capaci-ties of members and joints and asso-ciated criteria of each code, includ-ing member strengths in flexure,shear and bars anchorage, desirablehierarchies of strength attainment,deformation capacities of mecha-nisms of inelastic deformation, detailing of beams, columns andstructural walls, detailing of beam-column joints for shear and the detailing of diaphragms.
The second chapter compares themore significant issues dealt in theconsidered codes, including: seismicdesign actions and associated crite-ria, capacity design practice, beams,columns, confinement, structuralwalls and joints.

and associated degree of complexitymay significantly vary from one pro-ject to the other, which thus re-quires appropriate design and con-trol procedures.
While (foot)bridges remain demon-strative of UHPFRC structural effi-ciency, optimized serial elements forcivil engineering facilities (coverplates, slabs, connections…) repre-sent important volumes of UH-PFRC, maybe underestimated bystructural engineers in terms of eco-nomical weight. In some cases suchserial elements are key componentsof huge civil facilities.
UHPFRC use in earthquake engi-neering and retrofitting is verypromising and deserves significantresearch efforts due to the complexprovisions to be verified so as to en-sure structural ductility. Further-more, the use of UHPFRC as a deci-sive answer to durability-relatedrequirements seems to keep agrowth potential.
Several challenges and researchneeds can thus still be identifiedwith respect to the potential UH-PFRC development. And first of all,even if skilled architects, engineer-ing offices and UHPFRC experts getmore numerous, education of otherconcerned actors in specific issuesof UHPFRC technology and designremains to be pursued.
Although creative projects remaindecisive for UHPFRC attractiveness,cost and structural efficiency should
remain a key objective for a sustain-able and durable growth based onUHPFRC application.
The contractual frame of UHPFRCcould be reasonably updated in thecountries where industrial and large-scale experience has been gained. InFrance, a standardization processhas been launched which searchescompatibility with the EN format.
Some design issues still requireR&D efforts: seismic, shock and fa-tigue design; performance-baseddurability design; computed-aideddesign - especially non-linear analy-sis of complex 3D-shaped elements;post-cracking performance underfire; continuity with conventionalFRC/reinforced VHPC design.
The two 2009 and 2013 MarseilleUHPFRC symposia have demon-strated the usefulness of scientificand technical exchange based notonly on laboratory results, but alsoon the feedback and experience ofdesign, project realization, safety as-sessment, building and site durabili-ty of UHPFRC structures. Hopefullywe can find further knowledge ad-vances and new decisive lessonsfrom UHPFRC applications, to beshared in a next international sym-posium on UHPFRC in 2017!

Congratulations toRalejs Tepfers,Emeritus Professorat Chalmers Uni-versity of Technol-ogy, Gothenborg,who celebrates his
80th birthday this year. Ralejs wasborn in Rezekne, Latvia, but movedto Sweden with his family in 1944.He completed a Masters Degree inCivil Engineering at Chalmers Uni-versity of Technology, Goteborg, in1958, and after a brief period onconstruction sites in Sweden andSwitzerland obtained the position ofassistant in the Department ofBuilding Technology at ChalmersUniversity of Technology in 1960.Ralejs was appointed Professor ofBuilding Technology at Chalmers in1995, and Professor Emeritus on hisretirement in 2001. He has been an
Congratulations toA.S.G. Bruggeling,who celebrated his90th birthday ear-lier this year. As along-time activemember of FIP
and fib, Prof. Bruggeling chaired theFIP Commission 2 on PrestressingSteels and Systems. Under his chair-manship this was a highly efficientbody with respect to the develop-ment of design criteria and aspectsof validation by testing of pre-stress-ing steels and tendons. In 1974, thefirst edition of the FIP-Recommen-dations for the Approval and Accep-tance of Steels for Pre-stressing Ten-dons were published. The secondup-dated and enhanced edition fol-lowed in 1982. These recommenda-tions served for subsequent decadesas common international basis forthe acceptance of pre-stressing sys-tem. In fact, the EOTA-rules for theacceptance of post-tensioning sys-tems of 2012 are based on them. Besides these recommendations,Bruggeling’s commission dealt witha series of other highly importanttopics of pre-stressed concrete con-struction, e.g. protection of pre-stressing steel against corrosion,bond of pre-tensioned strands; non-metallic tensile element for tendons;cryogenic behavior of structural ma-terials for LNG vessels, etc. The re-sults of this work were published invarious FIP reports.
For fib, Bruggeling served as con-venor for the Task Group 9.4,“Bond of Prestressing Materials andTendons”. His wide-ranging workcovered many aspects of structuralengineering, including cable/stayedbridges, partial prestressing and pre-fabrications. He was a strong advo-cate for the introduction of the con-cept of “structural concrete” as anintegral approach to the design ofreinforced, prestressed and partiallyprestressed concrete. It was his con-viction this integral approachshould also apply to concrete and toconcrete structures. At Delft Univer-

sity of Technology, where he was ateacher and researcher from 1969 to1986, he realized this vision bymerging concrete technological andstructural research in one group.Moreover he convincingly propagat-ed his opinion that progress inknowledge of concrete and concretestructures is only possible, and evenacceptable, when based on sound,transparent modeling of physicaland mechanical behaviour.
His books on “Structural Concrete”and on “Prestressed Concrete forthe Storage of Liquefied Gases”were and still are landmarks in thedevelopment of reinforced and pre-stressed concrete. He is a honorarymember of many Dutch and interna-tional technical institutions and re-cieved honorary octorates from theTechnical Universities of Stuttgartand Leuven. He was awarded theFIP Medal in 1984.

active member of the Swedish Con-crete Association and served as theSwedish national delegate to CEB.
Ralejs contributed to several topicsin the field of concrete, but is proba-bly best known for the particularcontribution he made to the devel-opment of design rules for bond,much of which stemmed from hisdoctoral thesis, entitled “A theory ofapplied to overlapped tensile rein-forcement splices for deformedbars”, published in 1973. Somewhatunusually for a thesis, this went to asecond printing in 1976 as a resultof international interest in its con-tents. A major significance of thework embodied in the thesis was tooverturn the established conceptthat bond was solely a property ofthe bar, and to demonstrate the im-portance of both bar and structuralparameters. This work subsequentlyinfluenced the CEB-FlP Model Code1990. Since then Ralejs has contin-ued research into structural con-crete, particularly in fatigue of con-crete and FRP reinforcementmaterials. Under his convenorshipof various ‘Bond’ task groups a totalof three Bulletins were produced:CEB Bulletin 151, “Bond Actionand Bond Behavior of Reinforce-ment”, in 1981/1982, CEB Bulletin181, “Anchorage Zones of Pre-stressed Concrete Members”, in1987, and fib Bulletin 10 “Bond ofreinforcement in concrete”, in 2000.However, it was not just his techni-cal contributions that his TaskGroup colleagues appreciated. Healways brought out the best in themembers; he has a quiet charm andauthority which kept meetings mov-ing forward. He managed to maketask group meetings productive, en-joyable, and sociable. He retains ayouthful enthusiasm for his work,and is always seeking new ideas,and he offers great encouragementto young researchers, sometimes byoffering suggestions, in other casessimply being a good listener.

Congratulationsto Steen Rostam,a passionate advo-cate and promoterof methods for theservice life designof concrete struc-tures and other
matters concern with their durabili-ty, who will turn 70 this December.
Steen Rostam graduated from theTechnical University of Denmark,where he obtained his PhD in 1977and served as Associate Professor(halftime) until 1990. From 1972 tillhis retirement for health reasons in2004 he worked for COWI consult-ing engineers, being responsible forconcrete durability technology andactive in rehabilitation and servicelife designs in the Middle East, East-ern Europe, Russia and South Amer-ica. Among others, he was responsi-ble for the durability and 100 yearsservice life design concept for theGreat Belt Link in Denmark.
He made invaluable contributions tothe work of CEB and fib over sever-al decades.
