Wide flange beam section with J at end?

[MikeB8993]

I'm currently reviewing a soldier pile design and I came across a section designation that I have not seen before. The piles are W sections with the letter J at the end. It seems this is being added to section with flanges that are greater than 1.5" thick. I looked in the steel manual and there is a heavy section provision for sections with flanges greater than 2" thick, but nothing for 1.5". I haven't been able to find a good answer on Google either as adding J to the search makes it look for the torsion constant instead.

Anyone know what it means when "J" is added to the end of the section designation? Thanks!

If you gave us a scan of the drawing and the era when these were done, that might help. Us engineers are very visual.

It's not much of a drawing, more a revision markup of the drawing from a contractor. I asked if the J at the end of the section designation was a typo and was told it is correct. The section is a W14x211J. Apparently the contractor has a bunch of these sections and wants to use them.

From dusty memory, I seem to recall some WWF sections to have a post-script letter, but don't recall what the letters were anymore.

Jumbo?

I toured a local building project this winter that had this section used as a transfer beam, I believe. They said they had to ship it from Luxembourg.

Jumbo?

Unless they've changed the definitions, a W14x211 is not a jumbo section, since the flange thickness is less than 2 inches.

This supplier from Luxembourg has W14X211 listed in their "super jumbo" listing:

I have never seen post-script notations on wide flange sections before, so this is all guesswork on my part.

I couldn't get your link to work, but I looked up that company, and the do indeed list a W14x16x211 as a super jumbo column section. Apparently for columns, their super jumbos start at a flange thickness of 1". Their smallest super jumbo beam is a W36x231.

From what I read AISC defines a jumbo section as those that were formerly Group 4 or 5 section. In my steel manual, Group 4 W14 sections are W14x233 and heavier. My manual is nearly 30 years old, though.
