Hi there, I have a question regarding Appendix 4 of the 2004 edition: could you please confirm me that there is no "buckling security factor" requirement on this edition?

I know that on 2007 edition, chapter 5, this factor is considered.
I normally use it, but at the moment I have to study a problem on an item that was designed with ed.2004 and I don't understand if the designer had to meet a precise requirement on buckling loads...

Any help would be appreciated.
