摘要

The actions of a pile foundation on a structure are represented in commercial structural software bystiffness coefficients. These are usually calculated by approximate methods that typically neglect one ormore of the important factors that affect seismic response of a structure such as inertial interaction,kinematic interaction, seismic pore water pressures, soil nonlinearity, cross stiffness coupling anddynamic pile to pile interaction. A nonlinear 3-D analysis is used to calculate time histories of totalstiffnesses and structural frequencies for a typical bridge during an earthquake to demonstrate some of theconsequences of using various approximate methods.
