Abstract

A series of shaking table tests were carried out to study the kinematic response of flexible piles in layered soil deposits under seismic excitation. These tests were carried out in a deformable shear stack where the dynamic responses of the pile and the free field were recorded for various seismic inputs, soil configurations and pile head boundary conditions. The pile bending moments were measured along the length of the pile using strain gauges. The bending moment profiles are compared with the predictions made by three theoretical models of kinematic pile-soil interaction: (a) Dobry & O'Rourke (1983); (b) Mylonakis et al. (1997) and (c) Nikolaou et al. (2001). This study showed that the theoretical models predicted the maximum kinematic pile response with a variable degree of success. The observed differences can be attributed to the limitation imposed by the idealizations in the respective model regarding the non-linear nature of the soil.
