I am a structural engineer just started working in denmark. I would like to use eurocodes rather than using the danish standards as this will be easier for me from a language point of view. can anyone confirm if (1) they comply with danish buidling regulations, (2) which of the national annexes are available yet
Using eurocodes localized to national standards should cover your design requirements. Rule of thumb is not to mix different codes and standards.
Refering to danish building regulations as a national standard, yes, it overrides the general rules of eurocode.
The available national annexes should be furnished by your local standards administration.
