The Eurocodes

- case example

2121

A set of standardisedEuropean designstandards which provides acommon approach tostructural design acrossthe EU.

A suite of 10 EuropeanStandards for structuraldesign comprising 58parts.

Flexi ilit! in the use of the Eurocodes

Each part of the Eurocodes generall!consists of " portions#

$i% &ain code' and$ii% (ational Annex $(A%.

)he &ain code is used unaltered throughout the EU* uttranslated to the local language.
