I have been in contact with SEAOC members who will participate in the August 13 Seismology committee meeting. I was sent a draft of the Proposed Blue Book Section C805 - a four page document addressing the provisions of section 1630. I would recommend that individuals with specific comments regarding the application of the '97 UBC provisions for wood submit constructive comments (not simply emotional criticism ) to the seismology Listservice at seismo-all(--nospam--at)seaint.org. I do not know if submissions from outside the seismology committee can be posted on that list, but we should try. If not, I would request that one of the members who is participating on this list be willing to print our comments and submit them at the meeting for consideration. I wish to take this avenue because we are ridiculed for not participating in the code creation, blocked from participating by virtual means and ignored by the most members of seismology who support the new code but do not wish to discuss it with the general professional community. There must be an avenue to break down the barrier so that seismology members stop thinking of our discussions as personal attacks but the cries of those of us who need supportive information to apply the provisions of the code in a manner to insure our clients safety. Therefore, I remind all of our list members to submit their comments in as professional manner to be supportive of the need to open a line of communication between policy makers and those who are required to impliment policy.

Your info comfirms what had become readily apparent to me in the last two days since I finally began to get familiar with the rho factor on my own, reading the 97 UBC in its CBC-adopted edition I held out for, hoping it would bear corrections to glitches. I avoided the seminars and manuals in order to avoid being prejudiced by other people's notions until after forming my own from the code language itself. You confirm in your description that shear wall examples deliberated for the rho factor were concrete walls for tilt-ups, not wood panels like are ubiquitous in residential. This too I suspected. It is significant. And Bob Bossi confirms that it was Seismology Committee, not industry or others remote from SEAOC, that originated the rho factor, and that the committee has a combative stance toward dissenters. At this point I am going to copy in a message I sent privately to Dennis Wish very early this same day, Friday 7-30, before this thread took off. It will have to be in two installments. The first gives the results of my discoveries in the last two days about how haywire the rho factor is in wood frame work. It was readily discoverable just by taking an interest and testing among a few simple possibilities in a day's time starting cold. I thought the Committee did that sort of verification. The second part continues on the rho factor, and then gets into what I think the implications are for SEAOC, its damaged integrity, and a suggested reorganization to end the too-often recurrences of this type of debacle, which hits residential engineering practice and practitioners especially hard. This second part is brutal. But it is directed at problems that came from people, not at the individuals personally. Hurt feelings are likely, not improper, and not necessarily counterproductive. Many recent and present Committee members are respected friends from past years, and still will be. Charles O. Greenlaw SE Sacramento CA Past Seismology Comm.
