lrfd manual of steel construction aisc #
steel construction manual, 13th edition is aisc 325-05
manual of steel construction - allowable stress design (asd), 9th edition is aisc 316-89
what number has manual of steel construction - load and resistance factor design (lrfd), 3rd edition?
thanks.
i'm not sure exactly what you're asking.
the current 13th edition of the steel manual replaces the 9th edition of the asd and the 3rd edition of the lrfd manual. so the 3rd edition of lrfd manual was the previous one from a couple of years ago.
the "number" of lrfd 3rd edition was "3rd edition". that's what it should say on the book itself. not to be confused with the 3rd edition of the asd version, which was way back when. i've got the 5th edition of that (it wasn't called asd back then) and it's from 1948.
if you need a date (year) for the 3rd edition lrfd, or for the lrfd specification contained therein, perhaps someone with a copy of one could quickly look it up?
static12 - the lrfd specification does not have a specific number such as aisc 316 etc. the 3rd edition code is simply referred to as aisc lrfd (1999). note that this refers to not the entire manual but rather just the specification itself. this callout is how ibc and other model codes reference the specification.
asd manuals over the years:
1st edition through the 9th edition.
the 9th edition was the last asd manual
lrfd manuals came out after the asd 9th edition and
were called lrfd 1st through lrfd 3rd editions.
so aisc decided to make a combined edition and
added the 9 previous asd editions to the 3 previous lrfd editions and got 9+3 = 12. so the next edition was named the 13th...and its combined.
the next combined lrfd-asd edition will (i suppose) be called the 14th.
slight correction to the last post:
the 1st edition lrfd came out before the 9th edition asd (1986 vs. 1989).
i have all of them, sitting here on my shelf, since the first edition in 1927...
swearingen - thanks for the correction.
these people don't know what they're talking about. it's 325-01.
nutte - you are correct...we didn't read the question for its specific request.
i would be curious, though, nutte, as to where you found that number. i've searched the aisc website and the hard copy of the 1999 spec from the lrfd 3rd edition and see nothing about 325-01.
i searched and found that was the correct product code here:
funny that its not printed in the front of the manual or in the specifications. i've never heard of this "product code" number being used in any way shape or form other than on aisc's website.
