D5.D.3 Dutch National Annex to EC3

Adds values from the Dutch National Annex —titled NEN-EN 1993-1-1:2006+C1:2006/NB:2007— for use with Eurocode 3, or EN 1993-1-1:2005. The NA document makes small changes to the base document.

The clauses/sections in EN 1993-1-1:2005 (hereafter referred to as EC-3) that require additional clauses from the Dutch National Annex, NEN-EN 1993-1-1:2006+C1:2006/NB:2007, (hereafter referred to as D-NA) are described in the following sections.

Refer to the basic code (EC3) for a description of these clauses. The sections below refer to the corresponding clauses in the D-NA.

Note: Clause deals with a simplified assessment method for beams. STAAD.Pro only uses the more accurate method ( and in EC-3) and therefore this section is ignored.

The local axis convention in the Dutch codes is: Y – major axis & Z – minor axis (as opposed to the convention followed in STAAD.Pro).
