Abstract
‘]
This study investigates how varying soil types impact the seismic performance of a 30-story building,
simulated using ETABS software. The research focuses on key parameters such as soil type, different
shapes of structure, base shear, and inter-story drifts under different soil conditions, ranging from soft
clay to dense sand. By comparing fixed-base models with those incorporating soil-structure interaction
(SSI), the analysis highlights significant differences influenced by soil type. The findings reveal that
softer soils tend to amplify ground motion effects, resulting in higher displacements and inter-story
drifts within the structure. In contrast, stiffer soils provide greater stability but may transmit higher
forces to the building. These insights underscore the critical role of local soil conditions in structural
behavior during seismic events. They emphasize the necessity of considering SSI and soil variability in
the design and analysis of tall buildings to ensure their safety and performance under dynamic loads.
In conclusion, integrating SSI into structural analysis proves essential for accurate seismic assessment
and resilient design, particularly in regions with diverse geotechnical profiles. By understanding how
different soil types interact with building structures, engineers can optimize designs to mitigate risks
and enhance the overall seismic resilience of high-rise constructions.
