A new subsoil model for the analysis soil-structure interaction

Abstract

Three-dimensional description of building structure taking into consideration soil-structure interaction is a very complex problem and solution of this problem is often obtained by using finite element method. However, this method takes a signifi cant amount of computational time and memory. Therefore, an efficient semianalytical description procedure of subsoil, that could provide accurate results with signifi cantly reduced computational time is proposed in this study for the analysis soil-structure-interaction. The model allows the description to be made in three dimensional scheme and takes into account the complicated characteristic of subsoil strata. Because of the small number of unknowns the computation can be carried out easily on commonly used hardware of PC class. The examples prove the efficiency and the computing possibilities of the model.
