| Abstract | ||||
| This work is concerned with the shallow grid foundation resting on homogen ous soil. The interaction between grid foundation and soil, where the expected penetration may occur was observed. So, small and high deformation analysis types were performed. A comparison between results for various loading cases has been obtained. The nonlinear beha- vior of soil material was defined by hardening plasticity cap model while elasticity model was chosen for the foundation. The analysis variables for grid foundation were performed again for a regular rectangular raft foundation. The relative stress distributions inside the soil for the two foundation geometries 'grid and rectangular' have been observed. The finite element Pro- gram Abaqus cae V.7.1 is the used in the analysis. | ||||
