    2. AECEF - information • Overview of the process on harmonisation • of European codes and regulations in the • field of civil engineering construction • Current state of the process • EUCEET - Objectives of SP.7group CONTENTS OF THE PRESENTATION Brno 20 April 2004

    3. The Association of European Civil Engineering Faculties with the participation of CE faculties from non-European countries AECEF was founded under the initiative of the Faculty of Civil Engineering of the Czech Technical University in Prague in September 1992 http://www.fsv.cvut.cz/aecef AECEF Brno 20 April 2004

    4. 39 UNIVERSITIES AND INDIVIDUALS FROM EUROPE AND NORTH AMERICA: Canada, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Lithuania, Italy, Poland, Portugal, Romania, Russian Federation, Slovak Republic, Slovenia, United Kingdom, USA AECEF membership in 2004 Brno 20 April 2004

    6. AECEF NEWSLETTERS (2 per year) • SYMPOSIA • Prague: 1995 • Education for Civil and Environmental Engineering and Surveying • Odense: 1997 • Quality, Assessment, Trainee Services in Civil Engineering Education • Cardiff: 1999 • Civil Engineering Learning Technology • Porto: 2002 • Environmental Aspects • Moscow: 2004 postponed for 2005 • Theoretical Training, Civil Engineers of the 3rd Millennium AECEF activities: Brno 20 April 2004

    7. on harmonisation of European codes and regulations in thefield of civil engineering construction 1975: Decision of CEC (Commission of the European Community) on action programme in the field of civil engineering construction 1975 – 1989: First generation of European codes OVERVIEW OF THE PROCESS Brno 20 April 2004

    8. 1989: • CPD (Council’s Directive on Construction • products) • Council directives on public works and • services • Transfer to CEN (European Committee for • Standardisation): idea of ENV, later EN OVERIEW OF THE PROCESS Brno 20 April 2004

    9. 1992-1998: • Published 62 Prestandards (ENVs) • Supplemented by National Application • Documents (NAD) • Started harmonization of product standards • (hENs, ETAs, ETAGs) with ENVs • Since 1998: • Conversion of ENVs to 58 EN Eurocodes • Harmonization of product standards • (hENs, ETAs, ETAGs) with ENs Brno 20 April 2004

    10. EN Eurocodes: • Role of CPDInterpretative Documents : • Harmony with essential requirements • - No 1 Mechanical resistance and stability • - No 2 Safety in fire • Basis for contracts • Framework for harmonised product • standards (hENs, ETAs – CE marking) OVERVIEW OF THE PROCESS Brno 20 April 2004

    11. EN Eurocodes: Work coordinated by CEN/TC 250 (Chairman Prof. Bossenmeyer) EN 1990 Eurocode 0: Basis of structural design (1+1) EN 1991 Eurocode 1: Actions on structures (10) EN 1992 Eurocode 2: Design of concrete structures (4) EN 1993 Eurocode 3: Design of steel structures (19) EN 1994 Eurocode 4: Design of composite steel and concrete structures (3) EN 1995 Eurocode 5: Design of timber structures (3) EN 1996 Eurocode 6: Design of masonry structures (4) EN 1997 Eurocode 7: Geotechnical design (2) EN 1998 Eurocode 8: Design of structures for earthquake resistance (6) EN 1999 Eurocode 9: Design of aluminium structures (5) RECENT WORK Brno 20 April 2004

    12. Conversion of ENVs to EN Eurocodes (2002-10): • CEN/TC 250 • Project teams + National Technical Contacts • Guidance Paper L • Stages: • preparation of drafts (Stage 32 Stage 34) • examination period (Stage 49 for formal vote) • CEN process period(v, r, F+G Stage 64DAV) • translation period to national languages (max 1 year) • national calibration period (max 2 years after DAV) • coexistence period (max 5 years after DAV, DoW) Brno 20 April 2004

    13. EN Eurocodes will be supplemented by National Annexes (NA). • NA cover Nationally Determined Parameters (NDP) prepared by Member States for permitted national choice: • values and/or classes for alternatives • values for unspecified quantities • country specific data • choice of alternative procedures • (Note: safety remains national responsibility) RECENT WORK Brno 20 April 2004

    14. Stage 64 (DAV): 6 standards EN 1990, EN 1991-1-1, EN 1991-1-2 EN 1991-1-3, EN 1991-1-5, EN 1991-2 Stage 49: 16 standards Stage 34 or 32: 35 standards Other: EN 1993-1-7 (cancelled) CURRENT STATE (April 04): 58 EN Brno 20 April 2004

    15. Packaging of the EN • EN are grouped to enable a common date of withdrawal of relevant parts for a particular design: • EN2 (concrete): 3 packages • EN3 (steel): 6 packages • EN4 (composite): 2 packages • EN5 (timber: 2 packages • EN6 (masonry): 2 packages • EN9 (aluminium): 2 packages • EN0, EN1, EN7, EN8 are materially independent • and included into packages Brno 20 April 2004

    16. Packaging of the EN Example: Eurocode 3/1: Building and Civil Engineering Structures Basis of structural design (1): EN 1990 Actions on structures (7): EN 1991-1-1 EN 1991-1-2 EN 1991-1-3 EN 1991-1-4 EN 1991-1-5 EN 1991-1-6 EN 1991-1-7 Design of steel structures (7): EN 1993-1-1 EN 1993-1-2 EN 1993-1-3 EN 1993-1-4 EN 1993-1-8 EN 1993-1-9 EN 1993-1-10 Geotechnical design (2): EN 1997-1 EN 1997-2 Design of structures for earthquake resistance (3): EN 1998-1 EN 1998-3 EN 1998-5 Brno 20 April 2004
