Thank you all.
With the spread of medium and large sized wooden buildings, I have been researching in Japan on the reduction of shear wall performance due to small openings.
I found studies on doors and windows in foreign papers, but not on small openings.
So I asked the question.
How are penetrations in panel sheathed shear wall dealt with?
Do drilled pipe or small square penetrations, say for switch boxes, present a problem?
I could only find SBCCI Standard for Hurricane Resistant Construction SSTD 10-99, but this only targets windows, doors, etc.
