## 1 Introduction
In experimental methods, the standard spectral ratio method is used, which is obtained by comparing the frequency spectrum of loose units on the bedrock with the frequency spectrum of the bedrock itself [12; 13; 14; 15]. Another method involves obtaining the spectral ratios (H/V) of horizontal and vertical components using single-station micro-tremor records [16; 17; 18; 19; 20; 21; 22]. Several studies have examined the seismic performance of structures considering local soil conditions. [PERSON] et al. [23] investigated the effects of local soil conditions on target displacements in different earthquake zones for a sample reinforced concrete (RC) structure. In another study, [PERSON] [24] developed a model to estimate the shear strength of the column-beam joint zone, which is critical in RC buildings. [PERSON] et al. [25] revealed the effects of soil on the seismic behavior of a structure damaged in the 2018 Italy earthquake. [PERSON] et al. [26] examined liquefied soils in detail through a field study conducted after the 2014 Thailand earthquake. [PERSON] et al. [27] attempted to reveal the local field effects on soil responses in Eskisehir province. [PERSON] and [PERSON] [28] investigated the near-field fault effect of soil conditions on 20- and 8-storey RC building examples. [PERSON] [29] evaluated the relationship between soil and structural damage in the Istanbul region before a possible earthquake. [PERSON] et al. [30]assessed the impact of soil-structure interaction on the seismic behavior of structures using nonlinear finite element analysis. [PERSON] et al. [31] studied the effects of local soil conditions, as defined in the Turkey Earthquake Code, on storey displacements, section effects, and energy distributions in RC structures. [PERSON] et al. [32] evaluated the resonance effect by considering soil-structure interaction in the Italian city of Matera. [PERSON] et al. [33] numerically investigated the effects of local soil conditions on both design and cost for a two-storey RC building example. [PERSON] and [PERSON] [34] examined the effects of local soil conditions on structures with three different stories constructed in adjacent arrangements using the finite element method. [PERSON] and [PERSON] [35] (2021) evaluated the effects of local soil classes given in the Turkish Building Earthquake Code (TBEC-2018) on the seismic behavior of steel structures. [PERSON] et al. [36] studied the changes in sectional effects on an RC structure for different soil classes specified in the seismic design code currently used in Turkiye. Studies including both structural and geotechnical evaluations have also found a place in the literature following the 2023 Kahramanmaras earthquake, which caused great destruction for Turkiye. In studies evaluating geotechnical damages, ground-related damages were evaluated in detail. In these studies, soil-structure interaction was evaluated based on observation and they did not include any structural analysis [37; 38; 39; 40; 41; 42]. In some of the studies evaluating the damages in different structural systems, after the devastating Kahramanmaras earthquakes, within the scope of civil and earthquake engineering, there are numerical analyses for the structures selected as examples [43; 44; 45; 46; 47; 48; 49; 50; 51; 52]. Within the scope of this paper, the effects of local soil conditions were first evaluated in light of the 6 February Kahramanmaras (Turkiye) earthquake through numerical analysis. Structural analyses were conducted by considering seven different variables for four different local ground classes specified in Eurocode 8, which is widely used worldwide, for the selected RC numerical model. The variables selected included importance class, peak ground acceleration (PGA), damping ratio, the ground storey height of the structure (which is higher than the other storeys), the frame span of the RC structure, total number of storeys, and storey height.
