Özet:

 Earthquakes are natural disasters that pose significant risks to both historical and modern reinforced concrete and steel structures. In countries like Turkey, which are located in active seismic zones, ensuring the safety of structures is of critical importance. Seismic isolation systems, developed to minimize earthquake-induced damage, are effective engineering solutions that enhance the resilience of structures against seismic loads. In this study, the impact of friction pendulum isolators on seismic performance is investigated in accordance with the Turkish Building Earthquake Code TBEC 2018. A hospital building was designed using both the conventional approach and with seismic isolation, with the goal of achieving the target seismic performance level in each case. Numerical analyses revealed that seismic isolation increases the structural period, thereby reducing seismic forces, decreasing inter-story drifts, and minimizing structural deformations. Furthermore, a cost analysis of the isolation system was conducted, indicating that the cost of the isolated building is approximately 20 higher compared to a conventional reinforced concrete structure. Nevertheless, the study concludes that friction pendulum isolator systems represent a significant engineering solution for enhancing the seismic resilience of critical structures such as hospitals.

 Depremler, hem tarihi hem de modern betonarme ve çelik yapılar için büyük risk oluşturan doğal afetlerdir. Türkiye gibi aktif deprem kuşağında yer alan ülkelerde yapı güvenliğinin sağlanması kritik bir öneme sahiptir. Deprem hasarlarını minimize etmek amacıyla geliştirilen sismik izolasyon sistemleri, yapıların deprem yüklerine karşı dayanıklılığını artıran etkili mühendislik çözümlerindendir. Bu çalışmada, Türkiye Bina Deprem Yönetmeliği TBDY 2018e göre, sürtünmeli sarkaç izolatörlerin sismik performans üzerindeki etkisi konu alınmıştır. Çalışma kapsamında bir hastane binası, geleneksel yaklaşım ve sismik izolatörlü olarak hedef sismik performansı sağlayacak şekilde ayrı ayrı tasarlanmıştır. Sayısal analizler sonucunda, sismik izolasyonun yapı periyodunu uzatarak deprem kuvvetlerini azalttığı, göreli kat ötelemelerini düşürdüğü ve yapısal deformasyonları minimize ettiği belirlenmiştir. Ayrıca, izolasyon sisteminin maliyet analizi yapılmış ve izolatörlü bina maliyetinin geleneksel betonarme binaya kıyasla 20 daha fazla olduğu tespit edilmiştir. Ancak sonuç olarak, sürtünmeli sarkaç izolatör sistemlerinin, hastane gibi kritik yapıların sismik dayanıklılığını artırmada önemli bir mühendislik çözümü olduğu vurgulanmıştır.
