Abstract
Modeling soil-structure interaction subjected to harmonic load is important, particularly the harmonic problem at boundary domain. Calculation at the boundary is complicated due to the wave forwarded to the infinity and reflections that come back. Some research is conducted to develop a model that utilizes Integral transform to get response from the structure and its interaction with soil layer subjected to harmonic load. Methodology: A mathematical model is developed on the interaction between half space layer and the structure on it, with soil layer below (half space). The analysis utilizes a partial differential coupled Lame equation. Simulation results show that the developed model can calculate response from the structure and soil layer subjected to harmonic load by ITM – FEM coupling. Results carried out on layered soil show that the maximum amplitude resultant displacements Uz, depends highly on various loads that work in the half space layer, comparison of soil elastic modulus values El/E2, comparison of soil damping values ξ1/ ξ2, and also comparison of soil density value of each soil layer ρ1/ ρ2. The impact of El/E2 value on the maximum amplitude resultant displacements Uz is higher compared to the impact of ξ1/ ξ2 damping values or ρ1/ ρ2 soil density values.
