This report presents the design method of ultimate horizontal strength of abutments supported by the batter piles to protect against damage by an earthquake. Given its plastic deformation ability, this design method is judged more reasonable than the seismic coefficient method for a huge earthquake. The plastic deformation ability is analyzed by static nonlinear FEM with elastic and plastic buckling, because the ultimate horizonal strength of abutments supported by batter piles is generally governed by the buckling of the batter piles.
