The interest for a closer look on the effects of interaction between soil and structure increased
in the recent years due to structural requirements for safe and economic building. Soilstructure
interaction problem needs a realistic and precise description of the interaction of the
separate components –building and soil half-space-. The proceeding increase of computer
capacity allows the numerical modelling of the soil half-pace and the structure as a whole.
After that a one-step analysis can be performed. The finite element modelling of building is
usually available. Using of infinite or boundary elements for modelling of the unbounded
domain and the finite elements for modelling of bounded domain of a half-space offers
several advantages in soil-structure interaction analysis: The finite element modelling of the
near field offers the possibility of more accurate analysis within this domain. The geometrical
and material non-linearity within the near field can be considered easily. Modelling of the far
field can be carried out by means of either infinite element or boundary element method. In
present work a comparison between the two methods (boundary and infinite) will be carried
out with regard to formulation and advantages and disadvantages of the two methods.
