There are three analytical approximation approaches in . Most guidance on evaluating the seismic coefficient was based upon work done over 30 years ago that failed to take into account most of these factors. Recently, two new performance based approaches for establishing the seismic coefficient used in pseudo-static analyses of slope stability and retaining walls have been developed. Cantilever retaining walls have a large effective mass due to the soil placed over a horizontal section of the wall. These walls are typically constructed of cast-in-place, reinforced concrete. The horizontal (cantilevered) leg of the structure can either extend back into the retained soil or out away from the slope.
