Annotation: Three alternative designs of a foundation slab in three-dimensional representation with regard to the concrete features modification has been designed during the investigations. The data of the stressed and strained state of a foundation slab having made on the heart of the thin slabs theory of Kirchhoff-Love by adoption of three-dimensional finite elements with regard to the refining theories of Reysner-Nugda, Ambartsumyan, etc. have been obtained on evidence derived from the spatial design scheme of a high-rise building. The investigation object is the expediency evaluation of application of the spatial finite elements at the thick foundation slabs design. In accordance with the realistic conditions, the structural schematic drawing of a building has been simulated completely including the effect of the constant wind and seismic loads. A consequence of the obtained results is the fact that the simulating method enables to investigate time history of the stressed and strained state of a foundation slab both in layout and in thickness. The derivation of an optimum pattern of force transmission on to a pile foundation is also the significant findings of the investigations.
Keywords: foundation slab, spatial finite element, rigidity matrix, triaxial compression, stressed and strained state, pile foundation, three-dimensional model.
