Aims

Students will acquaint with several structures – soil interaction models used in the designing practice. Student will understand advantage and disadvantages of different models. They will be able to create pertinent solvation model of the foundation plates, grids or pile foundations and they will be able to solve this model using suitable FEM programs.
