OVERVIEW OF THE PROCESSOVERVIEW OF THE PROCESSon harmonisation of European codes and regulations
in the field of civil engineering construction1975: 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
Brno 20 April 2004Brno 20 April 2004 88
OVERIEW OF THE PROCESSOVERIEW OF THE PROCESS
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
Brno 20 April 2004Brno 20 April 2004 99
1992-1998: 1992-1998: • Published 62 Prestandards (ENVs) • Supplemented by National Application Documents (NAD)• Started harmonization of product standards (hENs, ETAs, ETAGs) with ENVs
Since 1998:Since 1998:• Conversion of ENVs to 58 EN Eurocodes• Harmonization of product standards (hENs, ETAs, ETAGs) with ENs
Brno 20 April 2004Brno 20 April 2004 1010
OVERVIEW OF THE PROCESSOVERVIEW OF THE PROCESS
EN Eurocodes:Role of CPD Interpretative 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)

RECENT WORKRECENT WORKEN 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)

Conversion of ENVs to ENConversion of ENVs to EN Eurocodes Eurocodes (2002-(2002-1010):):
• 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 64 DAV)• 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 2004Brno 20 April 2004 1313
RECENT WORKRECENT WORKEN 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)

Packaging of the EN 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

OBJECTIVES OF EUCEET SP.7OBJECTIVES OF EUCEET SP.7
Proposal from GA in Athens:• to collect list of background documents,
teaching aids or educational software for each EN Eurocode (or its part)
• to prepare list of specialists under EUCEET for possible future contacts • to propose „good practice” in teaching using Eurocodes
