D5.D.9 Singaporean National Annex to EC3
Adds values from the Singaporean National Annex - titled National Annex to Standard SS-EN 1993-1-1 - for use with Eurocode 3, or
EN 1993-1-1:2010. The NA document makes small changes to the base document.
Note: Refer to the basic code (EC3) for a description of these clauses. The sections below refer to the corresponding clauses in the Singaporean-NA.
The following clauses are not implemented in STAAD.Pro:
- Clause 6.3.2.4(1) B – Slenderness for flexural buckling
- The SINGAPORE NA specifies the value of λc0 for I, H channel or box section to be used in equation 6.59 of SS EN 1993-1-1:2010 as 0.4. However, STAAD.Pro does not use this clause for design per EC-3. Therefore, this clause is ignored for the Singaporean National Annex.
- Clause 6.3.2.4(2)B – Modification factor "kfl"
- The value of the modification factor kfl to be used in equation 6.60 of SS EN 1993-1-1. However, STAAD.Pro does not use this clause for design per EC-3. Therefore, this clause is ignored for the Singaporean National Annex.
The clauses/sections in EN 1993-1-1:2010 (hereafter referred to as EC-3) that have been dealt with in the Singaporean National Annex (hereafter referred to as SS-NA) and that are relevant to the proposed implementation are:
