How do you determine the kh and kv values for the mononobe okabe method?

Thanks!

For abutments on spread footings, AASHTO's Standard Specification (6.4.3) recommends k_h of one-half the acceleration coefficient. It says to omit the effects of vertical acceleration.

A great deal of information on this method--including those coefficients--can be found in The Seismic Design of Waterfront Retaining Structures, downloadable from
