Abstract
Characteristics of pile forces under seismic loadings are discussed from view points of the inertial interaction due to the mass effect of a superstructure and the kinematic interaction due to the resistance effect of piles against soil motions. A typical building supported on a pile group embedded in a layered soil, which has two- and four layer profiles, is chosen for studying the pile forces which imply the shearing force and bending moment. The earthquake response analysis is performed in accordance with the substructure method, in which the group effect of piles in the layered soil is appropriately included by using the Green's function derived from the thin layer formulation. The resulting pile forces are compared with those by the static analysis of a single pile applying the base shear force at the pile head. These numerical examples indicate that the kinematic interaction effect on pile forces should be properly considered in the seismic design of pile foundations.
