“…As indicated in Figure 17: S11: vertical stress in (x) direction, S22: axial stress in (y) direction, S33: axial stress in (z) direction, (S12 = S21): shear stresses in x-y plane. While determining the material properties for the minaret, the following literature works were followed Işık et al (2020) [62] and Işık et al (2022) [13]. The elastic modulus (E) and unit weight (γ) values of Bitlis stone were taken as a single value in all structures.…”

Masonry structures began to be built with the existence of human beings and are an inspiration for today’s structures. Monumental historical buildings built according to people’s religious beliefs have special importance among such structures. Despite being exposed to many natural disasters over time, such structures that have survived till today are an indispensable part of the historical heritage. Within the scope of this study, structural analyses were carried out for the historical Ulu Mosque’s minaret in Bitlis (Turkey), located in the Van Lake basin, using both on-site measurements and finite element methods. Detailed historical and architectural features were given for the minaret and the mosque. In addition to four different earthquake ground motion levels of 2%, 10%, 50% and 68%, structural analyses were deployed separately for seven different geographical locations in the same seismic risk area. Moreover, time history analyses were conducted using the acceleration records of the Van earthquake that occurred in the region. The minaret performance levels were determined by using the displacement values obtained. The study examined the different probabilities of exceedance and the changes in the regions with the same seismic risk. As a result of each structural analysis, base shear forces, displacement, period and maximum stress values were obtained for the minaret. The displacement, base shear force, and stress values increased as the exceedance probability decreased. While the same seismic and structural analysis results were obtained for the selected settlements in the same earthquake zone in this study, remarkable differences were observed for these settlements using the geographical-location-specific design spectrum.

Sismik etkilere karşı yapıların dayanım ve dayanıklılığını değerlendirmek ve depremlerin neden olabileceği hasarları en aza indirmek, deprem mühendisliğinin temel hedeflerindendir. Bu çerçevede deprem mühendisliğinde oldukça güncel olan sismik dirençlilik kavramı son yıllarda giderek önem kazanmaktadır. Bu çalışmada, herhangi bir afet sonrası yapıların eski haline dönebilme becerisi olarak tanımlanabilen Sismik dirençlilik konsepti, formülasyonları ile birlikte ele alınmıştır. Konsept olarak izah edilen sismik dirençlilik kavramının dirençlilik indeksi ile sayısallaştırılması bu indeksi oluşturan parametrelerden biri olan spektral ivme değeri değişken olarak seçilmiştir. Spektral ivme değişimine yaklaşımı farklı olan TBDY2018 ve DBYYHY2007 yönetmelikleri çerçevesinde 7 katlı bir betonarme yapı için Türkiye’nin 7 farklı bölgesinde 7 farklı şehir seçilmiş ve hesaplanan PGA değerleri esas alınarak kırılganlık eğrilerinden elde edilen dirençlilik indeksleri karşılaştırılmıştır. Bu karşılaştırma ile dirençlilik indeksi DBYYHY2007’e göre tüm şehirlerde sabit %99,7 iken değişken PGA değerleri ile TBDY2018’e göre %79,7-%99,6 aralığında hesaplanmıştır.

“…After each earthquake, significant loss and damage to life and properties emphasize the necessity to demonstrate the seismic hazard reliably. Therefore, determining the seismic risk of any region is an integral part of modern pre-earthquake disaster management [3][4][5][6][7]. This is also important for the seismic sensitivity assessment and retrofit decision making of structures [8,9].…”

Determining the earthquake hazard of any settlement is one of the primary studies for reducing earthquake damage. Therefore, earthquake hazard maps used for this purpose must be renewed over time. Turkey Earthquake Hazard Map has been used instead of Turkey Earthquake Zones Map since 2019. A probabilistic seismic hazard was performed by using these last two maps and different attenuation relationships for Bitlis Province (Eastern Turkey) were located in the Lake Van Basin, which has a high seismic risk. The earthquake parameters were determined by considering all districts and neighborhoods in the province. Probabilistic seismic hazard analyses were carried out for these settlements using seismic sources and four different attenuation relationships. The obtained values are compared with the design spectrum stated in the last two earthquake maps. Significant differences exist between the design spectrum obtained according to the different exceedance probabilities. In this study, adaptive pushover analyses of sample-reinforced concrete buildings were performed using the design ground motion level. Structural analyses were carried out using three different design spectra, as given in the last two seismic design codes and the mean spectrum obtained from attenuation relationships. Different design spectra significantly change the target displacements predicted for the performance levels of the buildings.
