By definition, "Story" is defined as: Space between levels. Story x is the story below level x. (Chapter 16, page 2-10 of 97 UBC)
From this I would use:
Level 1: 10' (Story 1, also Story Level 1)
Level 2: 20' (Story 2, also Story Level 2, roof)
2/3(height) = 13.3'
The maximum element-story shear ratio rmax is defined as the largest of the element story shear ratios, ri, which occurs in any of the STORY LEVELS at or below the 2/3 height level of the building.
My conclusion: At 2/3 height (13.3') you are AT the Story Level 2 shear elements and should therefore check rho in Level 2 elements and all levels below.
Since my initial post it occured to me to see what the Blue Book had to say about this issue. Section C18.104.22.168, 8th paragraph confirms my interpretation.
Now, how to firmly embed this in my mind so that when the question comes up again in our office 3 months from now......
