Hi all:

I previously asked here about replacing exterior wall structural
members after a termite infestation (http://tinyurl.com/kwndug) and
I've finally gotten around to actually doing the work.

Are there rules of thumb, building code sections or other guidelines
about how much damage needs to be done to a structural member before
it needs to be replaced? There are pieces of the framing (e.g., wall
studs) that have obviously been hit by termites, but where it seems
clear to me that the vast majority ( 75%) of the original wood is
still there and intact. I'd like to avoid tearing out "fairly sound"
pieces if I don't have to.

If it looks good, it probably is. For just wall studs, etc., wouldn't
worry about it much at all other than you'll need the surface edges to
hang sheetrock/siding to. If it's basically there but need that edge, a
couple of choices--a) scab a short piece to the side, or b) cut in a
piece to patch in the damaged section.

For "real" structural load-bearing members such as joists, headers,
etc., you'll want essentially the same load-bearing capacity as was
there initially just to be on the (perhaps cautiously) safe side.
