In design of pile structures used for port and harbor, and offshore structures which are to experience large deformation, analyses taking non-linearity of soil-piles system are needed.A common practice in analysing such pile-structures is first to evaluate deformation characteristics of the soil-piles system in terms of pile-top stiffness and then to perform a stress calculation of superstructures by the displacement method. However, it requires a considerable amount of calculation to find out the pile top stiffness satisfying the compatibility condition because the system is highly non-linear and superposition is not to apply.In this paper a method of non-linear analyses for lateral resistance of piles is proposed, featuring less computation volumes than those of the existing methods. Loading test data are examined to validate the method. A derivation method of the pile-top stiffness is also presented.
