Force transfer around openings CBC
Force transfer around openings CBC
(OP)
First, does anyone have an example of the "rational analysis" needed for force transfer around wood shear wall openings. This was talked about in a previous thread but I didn't really see a resolution (and this was IBC):

It seems like a "tic-tac-toe" method of designing each panel is necessay. Given a wood shear wall with one window opening (like Figure 12-II-1, 2001 CBC) does the wall pier recieve the shear drag across the top of the window opening? Is that force then used to design the horizontal and vertical straps along the window perimiter? If the force transfers through the strap to the bottom sill of the window, it seems like the shear panel below the window has shear capacity.
Second, is there a way to add the shear capacity of the moment resisting action of the "APA Narrow Wall Bracing" technique of 8d nails in a 3" O.C. grid pattern into a header at the top corner of a shear wall?
Thanks, Ben San Diego

LGROSSI - "..it´s two times bigger.." Does that mean it is three times as big? (i.e 2 times =200% => 200% bigger!). Sorry but this is a bad use of english that seems to be more common these days, be careful using that in reports as I am sure I am not the only one that will note the ambiguity.
