minimum window/wall distance from edges or corners
codes, books, ...etc state for an 8' wall a minimum distance for doors/windows from the corners or re-entrance corners is 2'-4". is there anyway around that using full studs + sheathing the inside & outside with plywood with 3" o.c. nail spacing. for a distance of 12" or 16". typical one story residence with comp. shingles and 5:12 pitch. the wall length is approximately 15' wide. i understand by adding plywood inside i decrease the shear in half and increase the capacity however, the distance is not met.???
any clarifications for my confussion will be helpfull.
the maximum aspect ratio of 3.5:1 applies regardless of the shear seen tin the wall. that is accommodated through variations in the nailing and stud size.
if you need a shorter shearwall length, you can do one of two things:
1. at the foundation level, you can raise the concrete stem wall until the plywood shearwall aspect ratio os 3.5;1 or less, or
2. you can do a perforated shearwall analysis. there have been discussions regarding this in the forum.
