## 4 Conclusions and Recommendations
Field observations of the Kahramanmaras earthquakes reveal that structures on soft soil suffered much more damage, which is in line with our numerical results that demonstrate larger target displacements for weak soil classes (ZD). Although further calibration using actual ground motion data might improve validation, this alignment demonstrates the dependability of our model. The findings of this study could impact seismic design practices in several ways: Structural target displacement limits could be adjusted based on soil class and damping ratio findings. Areas with soft soils might need more stringent building codes, particularly concerning frame span restrictions and damping improvements. Older buildings in soft-soil regions may require stiffness upgrades (such as base isolators or bracing systems) to mitigate the effects of increased displacement. The study's approach to assessing soil effects using Eurocode 8 classifications can be applied to regions with varying seismic risks. The findings on soft-soil amplification are particularly relevant for coastal cities and sedimentary basins, where seismic waves are more damaging. Cities with diverse urban development, such as Istanbul and Mexico City, could benefit from zoning policies tailored to soil variability. The pushover analysis used in this paper offers important insights into seismic performance, but it ignores frequency-dependent soil response and the impacts of cyclic deterioration. Nonlinear dynamic analysis should be incorporated into future research to more thoroughly examine these consequences. This study includes numerical analyses for medium-rise regular reinforced concrete buildings under different local site conditions. The study is based on reinforced concrete frame structures consisting of columns and beams. This and similar studies can be a source for irregular and high-rise reinforced concrete buildings with different structural systems. In this context, the effects of different parameters considered in this study on structures including RC shear walls, steel structures, and masonry structures can support future research. The effects of local soil conditions on torsion in structures containing irregularities can be examined in detail in other studies. In addition, more detailed studies on soil liquefaction and soil amplification will enable a clearer demonstration of the effects of local soil classes on the seismic behavior of structures. The varying conditions of soil, even within the same broad soil type, can significantly influence the seismic behavior of reinforced concrete structures. Differences between loose and compacted soils, for example, can lead to different responses in terms of how seismic waves affect a building's foundation and superstructure. The seismic behavior of reinforced-concrete structures is greatly influenced by the condition of the underlying soil. Loose soils tend to amplify seismic waves, increase settlement risks, and make foundations more susceptible to liquefaction, while compacted soils offer more stability, reducing seismic wave amplification and settlement risks. Engineers must account for these differences when designing structures, particularly in seismic zones, by considering soil properties in foundation design, structural reinforcement, and seismic mitigation strategies. This ensures that reinforced concrete structures remain safe and resilient during seismic events. Especially in Golbas and Hatay, soil liquefaction played a significant role in the destruction of buildings and infrastructure. For regions with similar sandy, loose, or water-saturated soils, engineers could adopt more rigorous soil-structure interaction models. These models would simulate the behavior of foundations during an earthquake, helping to predict potential settlement, tilting, or tilting caused by soil liquefaction.
