Principles
o Afterdiscussionthefollowingprinciplesforthefurtherdevelopmentof
Eurocode3weredecidedwithinCEN/TC250/SC3
Decision 4/2013
- keep the overall structure of EN 1993 and its parts
- improve the clarity
- harmonize and simplify rules (same format, structure, notations,..) and harmonize
different parts of Eurocode 3 and if possible also with other relevant Eurocodes
- reduce the overall volume (e.g. by avoiding informative annexes)
- reduce number of alternatives.
