Özet
<p>This study aimed to investigate the lateral behavior of steel pipe piles embedded in saturated sand by</p><p>considering the nonlinear behavior of both steel and soil materials. Nonlinear soil behavior was modeled using the</p><p>Pressure-Dependent Multi-Yield Surface Plasticity constitutive model, while the nonlinear response of piles was</p><p>represented with moment-curvature relationships. In this context, numerical simulations of 30 meter long steel</p><p>pipe piles with varying section and steel grades were performed considering specified pile head displacement</p><p>criteria. In addition to the nonlinear approach, simulations with linear elastic pile material were also conducted. In</p><p>this way, the pile responses under both material assumptions were comparatively evaluated. Results indicated that</p><p>as the pile flexural stiffness increased, the differences between linear elastic and nonlinear responses became more</p><p>significant. Findings highlighted the importance and influence of incorporating nonlinear material behavior in the</p><p>analysis of laterally loaded piles.</p>
