the impact of soil saturation on the seismic performance of a structure when
subjected to earthquake-induced vibration. More specifically, this paper examines
the effect of the soil saturation level taking into account of soil-structure
interaction (SSI) on the structural response. For this purpose, a two
dimensional (2D) finite element model was developed with Mohr-Coulomb failure
criterion under plane-strain conditions using geotechnical finite element code
PLAXIS. To emphasize SSI problems in civil engineering applications, mechanical
behavior and various saturation levels of the local soil condition is examined
using a numerical model. As can seen from the analysis results, the
saturation level of soils causes an increase on the lateral roof displacement of
the saturated elasto-plastic soil. This situation was interpreted as the
increase in the saturation levels of the soils caused a decrease in the
rigidity. Furthermore, neglecting the effect of SSI leads to underestimated
results of the structural behavior. </p> <p> </p>}, number={2}, publisher={Sakarya University}
