The paper presents initial structural and static analyses of an innovative type of foundation structure, which theoretically can obtain unlimited horizontal surface. This implies that the proposed system of combined foundation can be applied for construction of heavily loaded buildings located on subsoil of very small load carrying ability. Basic rules of theory of structures like the principle of superposition are respected during process of design of the proposed structural system. Important inspiration in this process have played patterns of stress trajectories in the free-end-beam as well as  shapes of the Michell’s beam. The inner build of the system of  combined foundation makes possible the very uniform distribution of the load forces onto its horizontal surface. Moreover this system has inherent structural features of a damper, due to which it is able to absorb safely a significant part of energy of vibrations evoked by earthquakes. Suitable application of the proposed system makes possible to design safe structures of high-rise building located in earthquake areas.
