RE: Perforated shear walls

Yes and also 20' wall heights and 4 more limitations. These provisions must be based on full scale tests? I don't understand how lowering the allowable shear with the adjustment factor justifies the lack of pier overturning and/or force transfer at openings. Not being argumentative, just want to be sure I understand it.

There is a limit of 490plf.  Above that they are not allowed.

Even in high seismic regions?

I have never designed perforated shearwalls before and I am reviewing section 2305.3 of the 2007 CBC and the 2005 AWC design examples. Do understand correctly that a perforated shear wall meeting the requirements and subject to adjustment factors, can be designed with only end wall holdowns and no force transfer detailing around openings?
