Dynamic analysis of a pile embedded in a half-space soil covered by a water layer is crucial for the designs of the pile foundations for bridges, docks and offshore platforms etc. In this paper, a coupled boundary element method (BEM) model is developed to evaluate the dynamic response of the pile. In the proposed model, the pile and half-space soil are treated as elastic media, while the water...

This paper proposes an alternative mechanism of pile failure in liquefiable deposits during earthquakes. This failure mechanism, based on pile buckling, is formulated by back-analysing 14 case histories of pile foundation performance during earthquakes and verified using dynamic centrifuge tests. A new parameter, the slenderness ratio of a pile, is introduced to classify pile performance in liq...

This research is to assess the influences of inertial mass from girder on dynamic characteristic, response, and structure-soil interaction a pile-soil-pier subsystem in scale-model cable-stayed bridge. Therefore, both connection configurations between girder, including sliding fixed connections, were designed present various superstructure delivered pile-soil-pier. The supported by 3 × pile-gro...
