Soil-Structure Interaction Analyses for Evaluating Seismic Response
The strengths and limitations of different methods of evaluating the effects of soil-structure interaction on the response of massive structures during earthquakes are reviewed. It is noted that significantly different results may be obtained by halfspace and finite element analyses of the same soil-structure system. However, it is also shown that wide variations in results may be obtained by either approach alone depending on the details of analytical techniques used and the method of evaluating appropriate soil properties. It is suggested that the major limitation of finite element analyses is the current inability to evaluate three dimensional effects, while the major limitations of halfspace approaches are that material damping effects in the soil are not considered, analyses are not available for multilayered soil deposits and the effects of adjacent structures are not usually evaluated.
