Approximate Solutions for Layered Foundations

by A. J. Philippacopoulos, Brookhaven Natl Lab, Upton, NY, USA,

Document Type: Proceeding Paper

Part of: Dynamic Response of Structures


A simple approximation to the dynamic response of foundations resting on layered soil profiles is presented. The approximation is based on an equivalent radiation damping which is numerically evaluated for different foundation configurations. Comparisons between approximate and rigorously computed foundation response are presented.
