RESOLUTION 280 (CEN/TC 250, Helsinki, 18th June 2010)

Subject: CEN/TC 250 – simplification of Eurocodes

CEN/TC 250 acknowledges the challenge established in the Programming Mandate

M/466 addressed to CEN in the field of the Structural Eurocodes to examine the

potential for simplification of rules in the further development of the Eurocodes.

CEN/TC 250 agrees to work towards achieving such simplification in the further

development of the Eurocodes to support the ease of their use by designers through:

(i) improving the clarity;

(ii) simplifying routes through the Eurocodes;

(iii) limiting, where possible, the inclusion of alternative application rules;

(iv) avoiding or removing rules of little practical use in design;

CEN/TC 250 agrees that such simplification should be limited to the extent that it is

technically justified and should seek to avoid additional and/or empirical rules for

particular structure or structural-element types.

The resolution was agreed by unanimity.
