Abstract

In order to obtain a theoretical prediction on the seismic response of the soil-pile structure systems, the frequency response of the soil-pile system excited by ground incident waves may be necessary in addition to the response due to the excitation at the pile head. This paper is concerned with a theoretical analysis based on the three-dimensional wave propagation theory to find dynamical interaction characteristics of an elastic pile embedded in the viscoelastic soil stratum on a rigid bed rock, subjected to a concentrated external force or forced displacement at the pile head and to uniformly distributed bed rock motion. In dealing with this complicated boundary configuration and exciting condition, the technique of superposition principle associated with the auxiliary sub problems is effectively used. And, the governing equations in frequency domain reduce to the Fredholm type integral equations of the second kind, whose solutions are expressed in terms of multiple summations and integrals.

Dynamical Behavior of a Pile Under Earthquake Type Loading

St. Louis, Missouri

In order to obtain a theoretical prediction on the seismic response of the soil-pile structure systems, the frequency response of the soil-pile system excited by ground incident waves may be necessary in addition to the response due to the excitation at the pile head. This paper is concerned with a theoretical analysis based on the three-dimensional wave propagation theory to find dynamical interaction characteristics of an elastic pile embedded in the viscoelastic soil stratum on a rigid bed rock, subjected to a concentrated external force or forced displacement at the pile head and to uniformly distributed bed rock motion. In dealing with this complicated boundary configuration and exciting condition, the technique of superposition principle associated with the auxiliary sub problems is effectively used. And, the governing equations in frequency domain reduce to the Fredholm type integral equations of the second kind, whose solutions are expressed in terms of multiple summations and integrals.
