What is your basis for using "equivalent solid thickness" as the basis for 
minimum reinforcing steel?  UBC minimums are based on a percentage of "gross 
cross-sectional area".  Since the definition for "net area" (at the front of 
the Masonry Chapter of UBC) refers to "gross cross-sectional area minus the 
area of ungrouted cells ...", I would interpret gross cross-sectional area
be the total area within the perimeter of the unit regardless of grouting.
