OVERVIEW OF THE PROCESSOVERVIEW OF THE PROCESSon harmonisation of European codes and regulations

in the field 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


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


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


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 WORK

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)


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)


RECENT WORKRECENT WORK

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)


CURRENT STATE (CURRENT STATE (April April 0044)): 5: 588 EN EN

Stage 64 (DAV): 6 standardsEN 1990, EN 1991-1-1, EN 1991-1-2EN 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)


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

(references, development, training courses available,

support, journal „Eurocodesnews“) ___________________________

CZ – under Leonardo da Vinci EC project:

(coordinated by Klokner Institute CTU in Prague + 7)

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
