Masonry Fences or sound walls per 1997 code

[structbear]

I don't know how the IBC requirements on this but per the 1997 code when designing for these type of structures within the equation there is (1+ hx/hr). For this type of structure, what does hx/hr equal to? I have used several different approaches and have not been questioned on this but I would like to hear other approaches.
