Scott, I didn't mean to ignore you, but even though we do have some Seismic Bracing requirements here in N.C. (yes it's true) I don't think I can meet your question with a quality answer from this side of the USA. [Linked Image]

Believe it or not, we have to have our in house engineer (likable person, as you are too [Linked Image]) actually sign off and seal our supports and sway installations on some hospital projects.

I wish I could give a more informed opinion, but I have only felt one earthquake in my 50 years, and that was hundreds of miles from here about 4 years ago, I think. (the age thing [Linked Image])
