Annotation: Ground design models significantly affect on the strain-stress distributions of foundations and superstructures, however, technical and regulatory literature degree of impact of this influence is not enough. The paper consider the basic ground design models, impact of the quantitative characteristics of ground design models for internal force in base slabs and bearing structures of frame buildings on slab foundation, and also quoted result of theoretical investigation on the basis of professional software package Lira. In the paper considered the following ground design models: 1) model, which is characterized by constant stiffness, 2) model, which is characterized by a variable stiffness, 3) model, which is characterized by generalized stiffness of professor Klepikov. In these models were compared: the value of vertical forces in the columns, the values of displacements along the axis Z, the bending moments in a plate foundation, and was giving a comparison of the results and recommendations of the selection of ground design model.
Keywords: ground design model, the Winkler model, the model of generalized stiffness professor Klepikova, linearly deformed half-space model.
