## 5 Results and Conclusions  
Although the history of masonry buildings dates back to ancient times, they could have been and could still be built from different building materials. Within the scope of this study, the usage of different material types for a sample minaret model was examined in detail. Within the scope of the study, previous studies for thirteen different types of minaret materials were compiled, and material properties were determined. In addition to the naturally obtained materials, the concrete material widely used today has also been considered. Structural analyses were performed for each material type, respectively. The modulus of elasticity, which measures the elastic deformation of materials under force, has the highest value for Suphan basalt and the lowest value for adobe. Among the materials considered, the material with the highest unit volume weight value is cut stone, while the material with the lowest value is Edremit traverting. While Poisson's ratio has the highest value for Diyarbakur basalt, the lowest value is obtained for Edremit traverting. In this study, the predicted values in the last two earthquake hazard maps and the seismic design codes used in Turkiye were compared for the selected location because of the need to use site-specific design spectra for the minaret according to the current seismic design code. As a result, the predicted PGA on the updated seismic hazard map (2018) for the selected location was lower than the previous one (2007). This may be different for different locations. It is known that the change of the design spectra obtained specifically for the site will significantly change the target displacement values predicted for the building performance. \begin{table}

Therefore, in cases where the target displacement values need to be adequately represented, it is impossible to determine the performance levels of structures under the earthquake effect accurately. While the highest period was obtained for adobe with the lowest modulus of elasticity, the lowest period was obtained for Suphan basalt with the highest modulus of elasticity. This situation remained valid for frequency values as well. As the elasticity modulus increases in the material, the period values decrease, causing the structure to behave more rigidly. The material elasticity modulus is a parameter that directly affects the rigidity of the structures. The period values obtained from the structural analysis results for all different materials. Meanwhile, empirical period formulas based on height were proposed for each material. Minaret wall thickness was chosen equally for all materials used in the sample model. It will be useful to examine the thickness variation in future studies. The proposed empirical period correlations were obtained only according to the height considered. This study will contribute to developing the relations obtained by considering different heights for these materials. According to the structural analyses considering the response spectrum, the highest roof draft was obtained at 38.5 cm for the adobe with the lowest modulus of elasticity. The lowest roof draft was obtained for Suphan basalt at 5.1 cm.
