2006 IRC 602.10.1 Braced Wall Line Offsets

2006 IRC 602.10.1 Braced Wall Line Offsets

2006 IRC 602.10.1 Braced Wall Line Offsets

(OP)
I'm trying really, really hard not to overdesign...

I'm a "regular" building structural engineer designing my own two story bungalow.  The main level is 39' (N/S) x 30' (E/W) and the upper level is 32' (N/S) x 30' (E/W).  Therefore, the southern walls are offset by 7'.  I have a friend who is a structural engineer who tells me that I can magically place a braced wall halfway between this 7' offset, such that my braced panels are offset 3.5' on either side of the braced wall line.  I already told him he was crazy, to which he responded that he has done this numerous times with plan reviewers and they find it acceptable.  Then I reread this line (2006 IRC 602.10.1):

"Braced wall panels that are counted as part of a braced wall line shall be in line, except that offsets out of plane of up to 4' shall be permitted provided that the total out-to-out offset dimension in any braced wall line is not more than 8'."

Is my friend's interpretation correct? Can I arbitrarily draw a line and count any shear wall within 4' on either side as part of a braced wall line?  Just when I thought the IBC wasn't clear enough...

Thanks,
David

Yep, you get 4' either way for leeway.  The 2009 IRC actually shows a drawing with this clearly explained.
