David,
I have spoke with another engineer who thinks R would be 5.6 under building frame system item 4a.
Do you mind clarifying R=4.4. Why would I assume the diagonal brace takes gravity loads?

I searched the archives and I am still unclear. I have a new wood framed residence that needs one story braced frames in one direction, mainly due to OT uplift requirements. The 2 vertical columns will take gravity load, but the top chord and single strut diagonal chord will not. What R should I use? We are submitting this in California before the end of the year.Thanks,Jeff
