RE: seismic text / FEMA

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I am not sure what you mean by the FEMA seismic evaluation handbooks. The ones that were published were not intended to be updated or sustained. The NEHRP process will continue on. If you would like to offer comments go to:
http://www.nehrp.gov/
This web site shows the relationship to FEMA, NSF, NIST, and USGS. There are no radical changes of which I am aware. Dr. Jack Hayes is the new director of NEHRP. He is very capable and dedicated to the NEHRP process. Dr. Hayes came from the US Army Corps of Engineers ERDC in Champaign. The BSSC under NIBS will still be the entity that creates the NEHRP Recommended Provisions. They will not look the same. The BSSC will still maintain and update the Commentary, but the Provisions will only supplement and not regurgitate the ASCE 7.

So does anyone have any opinion on the future of the FEMA seismic evaluation
handbooks now that it looks like FEMA is on the cutting block at congress?

FEMA 450 is the 2003 NEHRP Provisions, which for all intents and purposes is
a non-"codified" (i.e. not written necessarily in code/mandatory
language) version of the seismic provisions in ASCE 7. In other words, much
of what is in FEMA 450 will be very similar to what is in ASCE 7-05's
seismic sections.

FEMA 451 is the commentary for the NEHRP Provisions, which can also be used
to some degree as commentary for ASCE 7-05.

There was talk about 5 years ago that this relationship would change, but I
think that may have died a little bit.  The NEHRP Provisions fulfill two
basic roles: 1) they serve as a "breeding" ground for new seismis
ideas/methods that should eventually make it into use in design; and 2)
serve as a minimum seismic design document for the federal government to use on federal projects (by Executive Order...at that was the case a while ago). The second role is what causes/keeps the NEHRP Provisions so "close" to ASCE
7's seismic provisions...but there was talk that ASCE 7 Seismic Task
Committee (STC) would take over the code provisions type development and
leave the "advancements" of seismic design to the NEHRP committees.  As
such, in theory, the NEHRP Provisions in theory where going to stop
"replicating" much of what was in ASCE 7 (i.e. code like
provisions) and just reference ASCE 7.  This would satisfy the Executive
Order (i.e. give the feds a seismic design document for fed projects). Then
all that would be in the NEHRP Provisions would be "state of the art"
recommendations/methods for seismis design.  That was the intent...just
don't know where it went.

But, the point is valid.  FEMA 450 and 451 (espescially 451) are good, free
documents to help understand the seismic provisions in ASCE 7/IBC.

As to texkbooks, I am not aware of anyone in particular that is especially
good, but most modern structural textbooks of any of the various design
materials will likely have a least a short (chapter or subpart of a
chapter) on seismic design/loading.  There are also textbooks that
"specialize" in seismic design issue, but for many it is not clear if they
have been updated for the latest seismic design methods (i.e. current or
reasonably current ASCE 7/IBC provisions).

Likely the best things to look into might be some the "study guide" oriented
books that are aimed at helping prepare for the CA/WA SE exams. You will
just need to find one that has been updated to current IBC/ASCE 7 provisions
rather than 1997 UBC provisions.  There is a Seismic And Wind
Forces: Structural Design Examples, 2nd Edition available on the ICC website that at least is up to date to the 2002 editions of ASCE 7, ACI 318, and the
2002 MSJC and 2003 IBC.  Also it looks like Williams' SEismic Design of
Buidlings and Bridges (available on Amazon) has been updated to the 2003
IBC.

You will not find much, if anything up to the 2006 IBC/2005 ASCE 7 yet, but
stuff based upon the 2003 IBC/2002 ASCE 7 will be pretty darn close.
