This project consists of a dynamic analysis of Soil-Foundation Interaction, i.e. Soil-Structure Interaction (SSI) and Structure-Soil-Structure Interaction (SSSI). The aim of the project is to study different wave propagation patterns. This has been studied in time domain. The used frequencies will be representative for man-made environmental vibrations.
Firstly, the basic theory is explained and based on this theory, a simple model is described for surface waves.
Secondly, the finite element model is described and based on both models, a comparison between the methods is made.
After all basic properties and assumptions, the actual patterns in the soil is studied in time domain. Different parameters are analysed and their respective influence on the results is explained.
The last part of this project contains the SSI, wherein different foundation configurations are excited with pulse and harmonic loads and the vertical responses at another foundation, some distance away, are analysed. This results in a suggestion for simplification of the model.
