Combined Finite Difference/Finite Element Analysis for Soil Structure Interaction

by David John Stevens, Univ of Minnesota, Minneapolis, MN, USA,
Theodor Krauthammer, Univ of Minnesota, Minneapolis, MN, USA,



Document Type: Proceeding Paper

Part of: Dynamics of Structures

Abstract:

A method for the analysis of buried structures subjected to stress transients is presented. The method combines the finite difference and finite element techniques to provide the analyst with the capability to model the complete effects of soil-structure interaction, including material and geometric nonlinearities. The method and its computer implementation are briefly described and the results of two example analyses are presented.
