To let you in on a secret, some of the criticism of the code writing
process comes from those who have been involved in writing codes. I for
one served on the SEOC Seismology Committee, and least one other
contributer to this discussion participated in the process. I will let
this individual out himself.
The NEHRP document may have a broader geographic participation but from
what I have seen this is about where the differences stop. Both processes
were built on the same resource documents and many of the players were and
are the same.
I hear the protestations that the NEHRP process is more rational but my gut
feeling says that it is just as subject to vocal individuals pushing
through changes. I will also bet that a significant amount of time in the
NEHRP meetings is spent negotiating political comprimizes.
My point is not that we should not participate in the process but rather
that an effort should be made to address some of the political,
orginizational, and personality issues that so strongly influence which way
the codes are going.
When I was involved in writing the response spectrum provisions in the 88
UBC, there were a number of individuals involved whose understanding of
dynamics was weak and it would have been easy to dismiss their comments.
In many cases if you took the time to understand what they were saying
there was something worth considering. In the same light I think that
those who are participating in the code writing process should be listening
to the engineers who are complaining about the codes. The critics
proposals may not be the best solution, but on the otherhand it is wrong to
ignore the complaints.
One of the criticisms of the code writing process is that it is a fairly
closed process. It is great if you are on the inside but not so great if
you are on the outside. To deal with this I would like to propose that a
copy of the NEHRP document be placed on the internet along with copies of
all proposals of chages. The process is funded by government funds so
there should be no problem of ownership.
To support your contention that the code is international, you just need to
look to the Phillipines. Their structural code is a direct copy of the
1988 UBC. Even though the document is the same, the way it was interpreted
often differed considerably from standard practice in California.
