Article Preview

Based on interaction analysis of subgrade, foundation and upper structure, considering the effect of foundation deformation on upper structure loading behavior, the influence of soil stiffness on structure and foundation design is studied in this paper. With the finite element model of subgrade, foundation and upper structure, and the assumption of Winkler elastic foundation beam, the interaction between each other is calculated by ETABS and SAFE, in which the performance of subgrade deformation is simulated by surface spring.
