Design Concept of Pile Foundation to Lateral Load Considering Soil-Pile-Structure Interaction

To rationalize the aseismic design of pile foundations it is essential to make clear the load conditions applied to piles. This paper describes 1) the results of earthquake motion measurement carried out in and around a pile-supported building, 2) the simulation using soil-pile structure lumped mass interaction model and 3) case study of typical combination models of structure and soil. Fundamentally both the seismic loads of super-structure and the forced deformation by surrounding soil should be applied to piles as external loads. In the coupling and evaluation of these loads the dynamic interaction among soil, pile and structure plays a very important role
