I'm referring to the recently published by The Concrete Society---Guide to the Design of Concrete Structures in the Arabian Peninsula (http://www.concrete.org.uk/bookshop/detail.aspx?ID=1222). I want to use this recomendation together with UBC 1997 seismic parameters:
Ca= 0.060 (minimum from the above guide for Sc soil profile in Zone AG)
Cv= 0.083 (minimum from the above guide for Sc soil profile Zone AG)
R= ? (this is my question--what type of "moment resisting frame" should be using in Zone AG)?

Apparently you are referencing an older code. The use of Rw and the term seismic "zones" has been discontinued for quite some time.
That said, if you are in a region of low seismic risk as set forth in ACI 318-05 Section 184.108.40.206, you do not need to design for the seismic provisions of Chapter 21. But you may have some detailing to which you need to comply which is listed in Section 220.127.116.11.
