I'm using Enercal for a cantilevered retaining wall system and they have a 1.7H factor (it will multiply the force by 1.7) embeded in the design program - for where they suggest earthquake forces from the soil are entered for the design of the stem of the wall.
My question is either to use that 1.7H for the earthquake forces of the soil to the retaining wall stem or 1.1E which could be interperted as = 1.1(1.6H)= 1.76 as outlined in the 97 UBC.
Also, do any of you use the smilutaneous effects of the later pressures caused by the soil and active pressures as outlined in NAVFAC? Thanks!
