Point of ap/dication -. Prom the total pressure computed as
above subtract the static active pressure obtained by putting tlh = ccV =
h = 0 in the expression given in 8.1.1. The remainder is the dynamic
increment. The static component of the total pressure shall be applied at
an elevation h/3 above the base of the wall. The point of application of
the dynamic increment shall bc assumed to be at mid-height of the wail.
