RE: Perforated shear walls

> height to width ratios no longer apply

The height to width ratios would still apply, it just that the height would be taken as the height between the straps rather than the full height.

 

>is it ever really worth it to use them

We never use them, providing strapping, in my mind, is a must better system.   And at the end of the night I can sleep!

Chuck,

There was no strapping on the outside of the building, but it is possible that there could have been strapping on the inside.  So your are saying that if the openings are treated like an opening in the diaphragm, then the height to width ratios no longer apply?  Which all of the extra stuff to do calculate with perforated shear walls, and the reduction in shear capacity, is it ever really worth it to use them?
