<< I think the tie between the rigid/flexible diaphragm and the story drift
is that, if you think of the diaphragm as a deep beam supported on lateral
shearwalls, the deflection at midspan compared to the story drift (that is,
how much the supports move) is a good parameter to see if the diaphragm is
rigid or not. Just a thought.

You are correct, this is the thought behind plywood diaphgram rigidity
arguments. The arguments include the quality of construction, the affects of
every component upon the overall system - especially where discontinuities
If you go back over some of the posts, many of these variables were discussed.
