Thanks Ray, we seem to agree.
Now to carry it a step further, since there is no adequate way to evalute the
rigidity of this type of diaphragm, would there be a liablity to the engineer
that uses professional judgment to evaluate the condition as flexible
inasmuch as the methodology presented in the code would not be adequate?

I think that as a minimum, the plane of the gable would act as a diaphragm
the side walls with chord boundaries at the ridge board and eaves. The
rigidity would then be based on the half diaphragms on each side of the
I don't believe that it should be considered a rigid diaphragm for wood
framed structures either way.
