There is a great technical guide from the AF&PA written by Jeffrey Stone, PhD that covers perforated shear walls a little more in depth than the IBC does.  With lots of wall openings you should definitely think about using a perforated analysis with holdowns only at the extreme ends of the wall.  Check it out:

I have noted with interest the discussion regarding the Simpson tie-downs and framing.

I am just starting to look at a two story wood building with a huge number of windows.  Leaves little solid wall.

Anyone have any comments or ideas on where to get examples of such a perforated design?



I'm not comfortable with perforated wall design in a region of high risk. I would rather stack (if possible) narrow Hardy Panels or the new Simpson or TJ Panels or even use the Tie-down rod system with the take-up device (I can't recall the name of the system since we rarely do multi-story here in Golf Course and Mountain country). There are some very good proprietary systems that are available to solve the problem of having lots of openings but the best advice is what you were given by Dave - make sure you account for your load path connections from the roof down.
