thanks, bob. we don't have seismic loads here (northern mn). here's a
question for you--what gives a stiffer frame--sheathing the corners
with osb or let in bracing?
at this point after talking to the owner and the architect, i think i
am going to try the fiberboard. if it seems to shaky, I'll sheath the
corners.
