Abstract

This paper summarily describes the present status of experimental research on inelastic behavior of pile foundation and the horizontal soil resistance characteristics. Tests with the presence of both pile and soil so as to take account of the pile-soil interaction effects on pile foundation seismic performance are also summarized. The results of pile foundation seismic performance are reviewed, and the important problems in future research are proposed.
