Table 5: S\({}_{\text{S}}\) and S\({}_{1}\) values for different probabilities of exceedance in 50 years. Generally, the seismicity characteristics include some parameters such as faults or fault groups, the properties of the faults, the distance of structures from the fault, the earthquake history of the region, and the properties of previous earthquakes. In addition to these parameters, it is a well-known fact that local soil conditions directly affect the seismic behavior of structures and also modify the reference seismic hazard coefficients defined for the outcropping rock environment. Moreover, the building stock in the region is particularly important in terms of the damage and loss of life that may occur as a result of the earthquake. The adobe stone masonry style is widely used and generally consists of 1-2 floors, especially in rural areas in the Eastern Anatolian Region. Such masonry structures are built by local craftsmen and workers using local materials without any engineering service. The walls are used as carrier system elements, and they are built in a thick form in the masonry building stocks. These buildings, which are easy to build from local materials, are preferred due to economical reasons. Soil drips are generally used in the top covers of such structures. Thus, the earthquake performances of these large masses are quite low. The damages in these structures caused by earthquakes clearly reveal this situation in the region. Most of the buildings in the region are built by medium-height reinforced concrete (RC) structures together with the masonry structures. However, instead of these buildings, high-rise RC buildings started to be used in recent years. Steel and prefabricated structures are generally used in shopping malls and industrial structures. The interaction between the seismicity characteristics and local soil conditions is used for structural analysis. Earthquake design spectra obtained from different probabilities of exceedances can be used in this analysis. Differences in the design spectra significantly affect the target displacement in structural analysis. Structures which do not meet the target displacement demands at high values are clearly distant from the true values for the damage estimates and building performance.
