Abstract

A multi-step procedure is outlined for a complete seismic soil-pile-structure interaction analysis, within the format of kinematic and inertial decomposition. Vertical S-wave propagation is considered and the pile-to-pile interplay is treated with sufficient rigor. The method has been implemented for the seismic analysis of bridge piers founded on piles in multilayered soil; a computer code (SBIAP) has been developed to this end. A parameter study (in both frequency and tune domains) illustrates the capability of the method to predict displacements and accelerations of the superstructure as well as bending moments and shear and axial forces in the piles. The importance of soil-structure interaction, of the presence of various types of radiation damping, and of the size of the pile group is graphically demonstrated.

Simple Methods for the Seismic Response of Piles Applied to Soil-Pile-Bridge Interaction

St. Louis, Missouri

A multi-step procedure is outlined for a complete seismic soil-pile-structure interaction analysis, within the format of kinematic and inertial decomposition. Vertical S-wave propagation is considered and the pile-to-pile interplay is treated with sufficient rigor. The method has been implemented for the seismic analysis of bridge piers founded on piles in multilayered soil; a computer code (SBIAP) has been developed to this end. A parameter study (in both frequency and tune domains) illustrates the capability of the method to predict displacements and accelerations of the superstructure as well as bending moments and shear and axial forces in the piles. The importance of soil-structure interaction, of the presence of various types of radiation damping, and of the size of the pile group is graphically demonstrated.
