ABSTRACT
The complexity of the problems regarding the design of the foundation systems is due to the type of foundations and also, due to the type of the foundation ground. This fact makes the theoretical calculus models (example: Boussinesq, Newmark etc.) to become very laborious and the results do not take into account the real, elastic-plastic behaviour of the foundation ground. Today there exist complex calculus computer codes that allow to model and design 2D and 3D structures. The paper presents the possibilities offered by such a computer code, by modelling a continuous foundation under walls. The continuous foundation under walls is loaded eccentrically and for its modelling were defined materials with different physical and mechanical properties and also, contact elements between the ground and the foundation, respectively between the brick wall and the foundation. Beside the calculus of deformations and stresses, the computer code allows the calculus of the characteristics for dynamic loads and also, diffusion problems such as pore water circulation or thermal transfer problems. The possibility of modelling structures composed of different materials allows a thoroughgoing study of the co-operation between the structure, foundation and foundation ground, the computer code being used for the study of some theoretical aspects and also, for the design of structures.
