This paper presents an idealized 2-dimensional plain strain nite element seismic soil-structure interaction
(SSI) analysis based on a substructure method by using original software developed by the authors. To
investigate the e ects of SSI the following types of analysis were performed: linear SSI analysis and non-linear
SSI analysis. For the same structure, analysis was carried out by the procedure without the consideration of
soil-structure interaction. These computations were achieved for di erent peak accelerations: 0.15g, 0.30g
and 0.45g. In another case for a di erent site soil with a shear wave velocity of 200, 300 and 500 m/s,
a linear SSI analysis was performed. In the analysis, the radiation condition was fully accounted for, the
soil plasticity was modeled with the Von Mises failure criterion, basemat uplift was not considered, and the
action of gravity was not taken into consideration.
