Why are W8 sections unlisted in 3rd edn AISC Zx selection table?

Why are W8 sections unlisted in 3rd edn AISC Zx selection table?

(OP)
For instance, on pg 5-48 of the 3rd edtition, the selections stop at W10 x 12.  But in the 2nd edition, the W8 sections are listed in the Zx table...what's up with that?   

RE: Why are W8 sections unlisted in 3rd edn AISC Zx selection table?

Because most engineers have found that a W10 is the smallest bending member they use.  If you cope out an inch of the top of the beam to make the connection like a purlin to girder connection, then you don't have very much room to fit the 2 bolt connection into.  Besides, for bending the W10x12 is only 2 lbs heavier than the smallest 8.

RE: Why are W8 sections unlisted in 3rd edn AISC Zx selection table?

To discourage their use as beams, for the reasons stated above.

And to save room in the manual by having fewer pages.

Wouldn't be popular in Australia.  We use a lot of W8 and W6 beams for small spans.  But then we don't try to bolt to the web.
