Özet:

 There are countries with a significant number of historic masonry monuments located in seismically active areas and preservation of these structures is of great importance. Because the preservation and upkeep of these structures is a cultural, economic, and social need, seismic performance evaluation of historical masonry structures is a crucial issue to address. The behaviour of such structures under lateral seismic loads is complicated because of the interaction of the grouted and ungrouted masonry. A wide number of severe damages and collapses have been observed after historical and instrumental earthquakes in Istanbul, highlighting the vulnerability of these structures to seismic loads. This research investigates the seismic performance of a historical masonry structure named Rumi Mehmed Pasha is located in the city centre of Istanbul Turkey. A three-dimensional Discrete Element Model of the historical tomb was created in 3DEC. Eleven earthquake ground motions compatible 2018 Turkish Building Seismic Code were selected and scaled to evaluate the seismic performance of the numerical model. Static, modal, and nonlinear dynamic analyses were performed.

 Sismik olarak aktif bölgelerde yer alan çok sayıda tarihi yığma anıta sahip ülkeler vardır ve bu yapıların korunması büyük önem taşımaktadır. Bu yapıların korunması ve bakımı kültürel, ekonomik ve sosyal bir ihtiyaç olduğundan, tarihi yığma yapıların sismik performansının değerlendirilmesi ele alınması gereken çok önemli bir konudur. Bu tür yapıların yatay deprem yükleri altındaki davranışı, dolgulu ve dolgusuz duvarların etkileşimi nedeniyle karmaşıktır. İstanbuldaki tarihi ve aletsel depremlerin ardından, bu yapıların deprem yüklerine karşı savunmasızlığını gösteren çok sayıda ciddi hasar ve göçme meydana geldiği görülmüştür. Bu çalışmanın amacı, İstanbul un Üsküdar semtinde bulunan Rumi Mehmed Paşa adlı tarihi bir kagir yapının sismik performansını araştırmaktadır. 3DEC programı kullanılarak tarihi yığma türbenin üç boyutlu Ayrık Eleman Modeli oluşturulmuştur. Bu tarihi yapının sismik performansını değerlendirmek için 2018 Türkiye Bina Deprem Yönetmeliğine uygun 11 deprem yer hareketi seçilmiş ve ölçeklendirilmiştir. Statik, modal ve birbirine dik iki yatay doğrultudaki deprem kayıtları altında doğrusal olmayan dinamik analizler yapılmıştır.
