In this study, we demonstrate a new seismic design flow chart for pile foundations considering the deformation capacity of piles. 'Strength degrading factor' is defined as the coefficient to decrease the yield bending strength of piles according to their deformation capacity. This factor, which is like the structural characteristics of superstructure, is presented as the function of the ductility factor of piles. The function is introduced by the regression analysis of yield bending strengths of piles to their ductility factors calculated by earthquake response analyses. For the earthquake response analyses, five artificial and four observed seismic motions are selected. The applicability of the presented function is verified by comparing bending moment distributions of piles evaluated by the static incremental analyses and the theoretical solutions for the beam on an elastic foundation with those calculated by the earthquake response analyses.
