000011706 520__ $$2eng$$aSeismic design of extended pile-shafts requires a consideration of the influence of the surrounding soil on the overall response of the soil-pile system. A procedure for seismic design of extended pile-shafts for bridge structures is presented in this paper. The design methodology follows the displacement-based design philosophy, where a target displacement is specified as the basis for design to ensure good performance. The procedure is capable of incorporating soil effects into the design process so that the influence of soil stiffness and strength on the seismic response of the structure can be accounted for. The design procedure involves an iterative process to arrive the required amount of longitudinal reinforcement. Other outcomes of the design include the stiffness and strength of the structure and the local curvature ductility demand. The versatility of the procedure is illustrated using a numerical example, which shows that reliable design results can be obtained for a wide range of structural and soil properties. The proposed procedure is relatively straightforward to implement and is deemed useful for performance-based seismic design.
