Edit: Actually remember another job that had a W14x500, both as a chord of a transfer truss and then for some of the columns supporting the transfer.

Top chord of a 378 ft. long bowstring truss which used three, 4 inch diameter bridge strand for the bottom chord.
The flanges were 3.9 inches thick with a 2.165 inch web. Got them from Belgium I believe.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Dlclarkii, were those salvaged from the World Trade Center buildings, per chance? I find it unlikely that a fabricator would "just so happen" to have such sizes lying around. In preparation for a new job or left over from an old job gone bust, yes, but not as part of his general inventory unless he's intent on going out of business.
*EDIT: perhaps a better way to have worded this would have been: It seems to me that this was likely done to meet the requirements of high rise buildings and other structures that require members capable of taking extremely large compression members. W14 lends itself to being able to be rolled to a very large cross sectional area while keeping ry as large as possible. It is an "efficient" shape in that regard.

edit: Which is stupid, when you buy a beam you're paying for the stock length, not just the length you want. So someone paid for these full length pieces plus cutting charges but didn't want the drop. At 60¢/lb that's $300/ft x 35' is a $12,000 beam! Granted I probably wouldn't want these drops if I were a fabricator and have to find storage in my shop. Just moving them around would be a bear at 600lb/ft. Must be a government job with no budget in mind. Would hurt if one of these rolled on your foot, steel toes or not!

We had a circle saw with about a 6' dia. blade, and hundreds of machine tool teeth, which literally machined (took small chips, like a milling machine might) through stl. members like that. That saw had about a 5/16 or 3/8" kerf width. With that saw we didn’t have to mill the ends for bearing when we were done cutting them to length. We also had a band saw type cutting system which would have worked. Then we had and end milling machine to dress the ends square and flat for end bearing.
