Abstract
Purpose: The aim of the work is to determine the stress-strain state of raft foundation split-level base of a massive concrete-steel building in linear and nonlinear formulation of the soil behavior with respect both and on the lateral surface of the at the foundation.
Methodology/approach: The stress-strain state of the split-level base as a layered material in the base–foundation–building system is performed by the finite element method using the verified software package Ing+ 2021 MicroFe.
Research findings: It is shown that in the constructively linearly/nonlinearly deformable earth foundation, its absolute displacements and relative difference in vertical displacements correspond to the service limit state.
