he steel construction manual

the steel construction manual
we are using a drawing (4-12-07) for a new steel erection project started in january 2008, referencing the "ninth edition of the steel construction manual"
i understand the 13th edition is the current document.
does the ninth edition reference aisc 346 (cancelled in 2005) and replaced by aisc 360-05?
we keep finding references to aisc 346 currently; in particular "design formulas for gapped k-connections, and t-, y-, and cross connections stiffened with plates." section 8 in correspondence from our safety group.
are stiffening plates still recommended for k-, t-, y-, connections?
thanks.
i am not a structural engineer, my specialty is marine     o & m engineering.

check out our whitepaper library.
are you dealing with hollow structural   
yes, hollow structural   
i can't find any reference to aisc 346 in the 9th edition
thanks,we were having some base metal cracks after assembly and the safety folks were quoting aisc 346, we ran an analysis and found it was an assembly problem which hopefully has been corrected by the a&e and contractor.
really appreciate your support.
thanks,
joe
