## 1 Introduction
Although there are no structural analyses in most of these studies, structural damage was investigated as a result of field investigations. In this paper, numerical analyses of the sample RC structure were carried out. Therefore, the aim is to reveal whether the target displacements caused by earthquakes in the structure are adequately represented. Within the scope of this study, the causes of damage in RC structures were investigated in detail as a result of studies carried out by the authors in the field. Because the earthquakes affected a very large region, only the RC structures in the city center, Golbasi, and Kahta districts of Adiyaman were taken into account in this study. The structures were subjected to detailed observational examination. Considering all the parameters that will directly affect the behavior of the buildings under the influence of earthquakes, the cause-and-effect relationships of the structural damage have been revealed. In this context, the main causes of structural damage were evaluated under 11 different subheadings. Structural damage for each parameter was exemplified. The study also gave information about the earthquakes on 6 February 2023. In the study, numerical modeling was carried out for a sample RC building, using the measured and predicted PGA values. An attempt has been made to reveal at what levels the target displacements are sufficient or not. In this study, peak ground acceleration (PGA) and design spectral acceleration coefficients (S\({}_{\text{DS}}\)) for Adiyaman districts were compared specifically for the last two earthquake hazards map that used in Turkiye. 6 February 2023 Kahramanmaras Earthquake and Its Effects on Adiyaman (Analysis of the Response Spectra and Strong Ground Motion Records)  
The city of Adiyaman in the Central Euphrates region of south-eastern Anatolia is located between 37\({}^{\circ}\)25\({}^{\prime}\)-38\({}^{\circ}\)10\({}^{\prime}\) N parallel and 37\({}^{\circ}\)27\({}^{\prime}\)-39\({}^{\circ}\)15\({}^{\prime}\) E meridians. It is bordered by the Taurus Mountains in the north and the Euphrates in the east. The city has hosted many civilizations in the transition zone between the historical Anatolian geography and Mesopotamia. Mount Nemrut National Park, a world heritage site, is located within the borders of Adiyaman. The city's center has formed its development around Adiyaman Castle, an archaeological site today. Adiyaman city center, Golbasi, and Kahta districts constitute the scope of this study. Adyaman is located in the East Anatolian Fault Zone (EAFZ), one of Turkiye's two important fault zones. Specifically, Golbasi was built on one of the important segments of the EAFZ. The seismically active East Anatolian Fault Zone (EAFZ) is one of the most important active tectonic structures of the eastern Mediterranean region. The EAFZ, a left-lateral strike-slip fault, and the NAFZ, a right-lateral strike-slip fault, cause the Anatolian microplate to move westward. The EAFZ was first described as a transform fault by [PERSON] and [PERSON] [33]. The 295 km long eastern section of the EAFZ, between Karlova and Celikhan, has a narrow deformation zone, observed as a single fault trace, except for the step-over structures (Figure 2). On the other hand, it divides into northern and southern fault strands in the west of Celikhan and is observed as a 65 km wide deformation belt [34]. The southern strand, which is the main fault zone, has a total length of 580 km between Karlova and Antakya and is divided into 7 fault segments called Karlova, Ilica, Palu, Putilrige, Erkenek, Pazarck, and Amanos from N-E to S-W [34; 35; 36]. Segment lengths vary between 31 and 112 km, and their strikes vary between N-35\({}^{\circ}\) E and N-75\({}^{\circ}\) E. The northern strand, which is called the Surgu-Misis Fault System, exhibits a left-lateral strike-slip fault segment of approximately 380 km between Celikhan and Iskenderun Bay [34].
