In this case, what would be the date of "official" adoption? (i.e. when
would engineers be expected to actually USE it?)
Also (and I hope I'm not asking too much) could you give us a BRIEF overview
of significant changes or additions?

Subject: RE: AISC 1999 LRFD Spec.
Tha ballot of the 1999 LRFD Specification is just now being finalized. Then
it has to be printed. Then a Manual has to be written around it. I expect
that you'll be able to get a copy of the finalized specification some time
this summer. Watch Modern Steel Construction magazine for an announcement.
As far as the Manual goes, it will take us to about the end of this year to
write the manuscript. Printing will then run it into being available (I'm
anticipating) by the Spring of 2001.

Subject: AISC 1999 LRFD Spec.
I have been reading your interesting comments on the list, and in the last
one you have pointed out a very important issue:
>Since then, there have been two revisions of the LRFD Speciication: the
1993 revision (in print) and the 1999 revision (being >finalized right now).
In each of those revisions, a little more has been added that differentiates
LRFD from ASD. The 1999 LRFD >Specification will have, among other things,
explicit treatment of srength and stiffness requirements for stability
bracing for beams, >columns, frames, etc., a section on evaluation and load
testing of existing structures, and a major improvement to fatigue
When it is expected to be published (and when AISC is expecting to sell it),
and which other major changes are addressed on it.
