I would appreciate anyone who can doing me a favor. I have been trying to dig
through the SEAInt archives for over an hour and can't find the messages I
remember reading last fall. Back then I was casually reading all the
messages on 10/Lw term in the RHO calculation for UBC Eq. 30-1. I remember
reading about the term being derived for concrete and masonry shear walls
and was not originally intended for plywood shear walls. Someone wrote a
very interesting message summarizing the history of the code provision. Back
then I was not doing any plywood shear walls and didn't pay too close
attention. Now I am and I am trying to recall what the resolution was. I
remember some were saying it should be 4/Lw for plywood shear walls, others
were stating you had to use 10/Lw because that was in the adopted code.
If anyone personally saved the discussion on this issue, would you mind
forwarding a copy of it to me please? I also remember that someone from ICBO
or SEAOC stated that there was going to be a magazine article written to
clarify it. If you have any of those messages I would appreciate it as well.
Send the messages to me directly. Don't clog up the list server with these
Thanks so much.
