Abstract
This study presents a detailed finite element modeling (FEM) investigation of soil–structure interaction (SSI) for shallow and deep foundations as understood up to 2017. The work examines the effects of soil nonlinearity, foundation stiffness, and loading conditions on the stress distribution and settlement behavior of foundations embedded in various soil profiles. A series of two-dimensional plane strain FEM analyses are conducted using established engineering software and constitutive models available by 2017. Key findings reveal that nonlinear soil behavior significantly alters load–settlement curves and that neglecting SSI can lead to unconservative designs. Recommendations for incorporating SSI in geotechnical design are provided.
