## 1 Introduction
Numerical analyses are also included in some of the studies in which structural damages in adobe, masonry, prefabricated, RC, mosque, and minaret-type structures located in the entire earthquake region or in any settlement affected by the Kahramanmaras earthquakes are evaluated within the scope of civil and earthquake engineering [48; 49; 50; 51; 52; 53; 54; 55; 56; 57; 58; 59; 60; 61; 62; 63]. Buildings built without complying with earthquake-resistant building design principles are the factors that cause the most loss of life and property in earthquakes. Studies to be carried out on the existing building stock before earthquakes can be used as an important support tool for decision makers. Within the scope of this study, rapid assessment methods used to determine risk priorities for detailed analyses of existing structures were used for reinforced concrete structures damaged at different earthquake levels. The aim of this study is to clearly reveal the pre- and post-earthquake effects of the parameters taken into account in the rapid evaluation method. The data obtained from buildings were subjected to a real test after the earthquake, hence representing, in a sense, a validation of rapid assessment methods. In this study, five RC buildings selected from each of the three provinces affected by the Kahramanmaras earthquakes were considered. An attempt was made to determine regional risk priorities both within each province and among all RC structures taken into account in this study. For the buildings taken into consideration, the rapid evaluation method used for RC structures in Turkiye was used, which was updated in 2019. Building data obtained as a result of field investigations and other data required to use the method were obtained in the office environment and a structural system score was obtained for each building. Risk prioritization was made among these selected buildings using the obtained scores. Within the scope of this study, numerical analyses were carried out for the soft/weak storey, which causes the most damage and is one of the important parameters in the rapid evaluation method. Separate structural analyses were performed for two different RC structural models for each of the three provinces. In one of the models, all storeys were chosen to be of equal height, while in the other model, the ground story height was chosen to be higher than the other storeys. This research addresses a critical topic in the field of civil engineering and emergency management, namely the assessment of RC structures after the 6 February 2023 Kahramamas (Turkiye) earthquakes. In this study, first of all, the method considered and all the necessary details for using the method are given. Each irregularity parameter is supported by pre-earthquake images. An attempt has been made to show the importance of the factors taken into account in the rapid assessment methods that have a direct impact on earthquake damage to buildings. Unlike our other studies, the 2019 Turkish Rapid Assessment method is used for the first time for RC structures damaged after an earthquake. The unique originality of this research lies in the application of the Turkish rapid seismic assessment method to evaluate damaged buildings after the Kahramanmaras earthquakes. By focusing on a specific geographical context and utilizing a systematic approach to assess structural integrity, this study presents a novel framework for risk prioritisation. The scientific validity of the findings is supported by a robust methodology that includes field observations and comparative data analyses in several affected provinces. Overall, the research highlights significant structural irregularities, such as soft or weak storeys, which contribute to heightened vulnerability during seismic events. Investigating the impact of different ground-storey heights provides valuable insights into design flaws that can exacerbate damage during earthquakes. This aspect emphasizes the need to adhere to the principles of earthquake-resistant design.
