Re: Steel shape availability grey tables

[Subject Prev][Subject Next][Thread Prev][Thread Next]
They used to have the Zx (Plastic Modulus) tables in the Silver LRFD book that had BOLD LETTERING for the MOST ECONOMICAL shapes...don't have the new one here at home to see if they've carried it over. In the LRFD, the shading usually indicated 50ksi steel, but now with A992 can't remember what the new manual does (YES, I STILL RELY ON THE SILVER LRFD BOOKS)

I'm sure Charlie C can help you out.

Why is it that the new AISC manuals do not have the grey shaded areas in the shape tables for sizes that are foreign produced or typically mill order?


I always liked having the grey lines in the table to give you a heads up before specifying that the shape maybe really hard to get.  Is there a separate section in the manual that I am not keyed into that provides the same info?
