“…As usually, design of structures for earthquake resistance considering soil-structure interaction is very complicated problem requiring a sufficiently long computation time and having a large number of uncertainties and assumptions [12][13][14][15][16]. As an alternative, the shakedown [17-19] seismic analysis of structures, taking into account the elastic-plastic and brittle behavior of their elements, was presented in the work [2]. In this article, such seismic shakedown analysis of structures is proposed to be performed taking into account the soil-structure interaction.…”

In this article, the seismic shakedown FEM analysis of reinforced concrete and composite spatial frame structures on the deformable foundation, taking into account the elasticplastic and brittle behavior of structures elements, is presented. A foundation consists of group of the piles in the soil. The behavior of soil is described here using+ the elastic halfspace theory. The pile deformation model is assumed to be elastic-perfectly plastic, where the bearing capacity is determined by the results of testing the soils or the piles themselves. An example of seismic shakedown limit analysis is presented.
