Process to ultimate condition under lateral load about fixed headed bearing pile are examined by elasto-plastic analysis. (1) Pile length L, assumption of plasticity and rotation of footing influence on lateral load and deformation at first plastic hinge formed. (2) According to the ratio of ultimate bending moment My_2/My_1(at pile top and maximum moment along pile length), the order forming plastic hinge is changed. (3) Failure mode is 2 hinges in the range of My<Ma and L> L_L but is 1 hinge structure out of those ranges. Ma is 0.85c_uBL^2 and L_L is √<Ma/0.85 c_u B> in the range of in L=6〜10m, Cu=1.5〜4.5 tf/m^2.
