Özet:

The behavior of soils under dynamic loads is of great importance. Waves moving from the bedrock towards the surface during an earthquake change by the ground conditions in which they are located. For this reason, variations in the frequency and amplitude of earthquake waves occur, sometimes they are subjected to damping and sometimes they encounter to an amplification effect. By determining the accelerations that the structures will be exposed to during an earthquake, it is ensured that safe structures are built in earthquake zones. For the design of structures under dynamic loads, it is of great importance to know the characteristics of the earthquake on the ground surface along with the dynamic behavior of the soil. The faulting structure of the region should be investigated in the field-specific soil amplification analysis. This study was carried out in Afyonkarahisar province, which is located in an active earthquake zone. After the drilling work carried out in the region, eleven earthquake acceleration records were selected considering the seismicity of the region and one-dimensional non-linear soil amplification analyses were performed by scaling site-specific according to the Turkish Building Earthquake Code (TEC 2018). In the analyses, the surface response was calculated using the DeepSoil program, and its performance was examined by obtaining the response spectra proposed by TBDY 2018 for the region. According to the results of the analysis, it was determined that local soil conditions affected the surface behavior. Although the plateau region of the design regulation was generally matched by the non-linear analyses, it remained on the unsafe side for the long periods.
