Background to Eurocode 2

The background to Eurocode 2 can be traced back to 1975 and the Treaty of Rome. The European Commission asked CEN (Centre European de Normalisation) to draft structural design standards that could be used across the Common Market.

The first published draft of Eurocode 2 was produced in 1985. Following a period of comment the voluntary ENV version was produced in 1993. After another period of comment, the current version of EN 1992 was produced under UK Chairmanship and secretariat. The main background is considered to be fib Model Code 1990 but provisions were modified in committee.

Revision 2020

In common with other Eurocodes, Eurocode 2 is due for a published revision in 2020.

CEN/TC 250

Revisions to the Eurocodes are being supervised by the head European structural design committee, CEN TC250. The current priority for TC 250  is the response to Mandate M/515 (Dec 2012) for ‘amending existing Eurocodes and extending the scope of structural Eurocodes’. This will involve:

(i) Development of a new Structural Eurocode on glass
(ii) Revisions to the existing codes to cover:

  •  improving the ease of use of the Eurocodes, particularly for day-to-day calculations,
  •  increased harmonisation through a reduction in National Determined Parameters, or convergence of values used,
  •  aspects of the assessment, re-use and retrofitting of existing structures,strengthening of the requirements for robustness.

(iii) Essential maintenance of the existing Eurocodes.
In 2014, TC250 undertook a systematic review of all Eurocodes and comments received were used and/or disseminated to subcommittees. A Chairman’s Advisory Panel conferred and determined that the primary audience for the revised standards was to be practicing engineers and the prime target was to be ease of use.
Redrafting of the Eurocodes will be undertaken by Project Teams to be appointed during 2015.


CEN/TC 250/SC2  

The committee dealing with Eurocode 2, CEN/TC 250/SC2 has been reviewing EN1992 for some time. Its SC2/WG1 has responsibility overall for the revision, for editing and for 10 Task Groups:
TG 1 – Fibre reinforced strengthening
TG 2 – Fibre reinforced concrete
TG 3 - Assessment
TG 4 - Shear, p shear & torsion
TG 5 - Fire
TG 6 – Structural analysis
TG 7 - Time dependent effects
TG 8 – Fatigue
TG 9 - Bridges
TG 10/JWG - Serviceability Design
As at mid 2015, the main areas of contention were punching shear, shear, cracking, detailing and assessment and generally progress was good. The revised EN1992 is due to be published in 2020 but . . 


BSI B525/2

As of mid 2015, the UK mirror committee B525/2 had submitted 220 of the 1168 comments being considered by WG1 and its TGs. B525/2 has representatives on the WG and each of the TGs above. B525/2 continues to monitor progress.
