Historical masonry arch bridges which are important components of the transportation in many places worldwide are invaluable part of architectural and cultural heritage. These bridges, which date back to hundreds of years, have frequently been damaged or ruined because of unexpected events such as earthquakes. In this study, earthquake behaviour of a historical masonry arch bridge which called Dutpınar is analysed using 2003 Bingöl earthquake acceleration records. The bridge is modelled with three dimensional finite element software. Dynamic response of the bridge is investigated. For this purpose, displacement of the nodal point located at the top of the bridge is achieved. Also, maximum and minimum principal stress and strains are obtained and potential locations of initial damages are evaluated.

Osmanlı İmparatorluğu Klasik Döneminin önde gelen mimarlarından Mimar Sinan tarafından tasarımı yapılan köprülerin birçoğu, kullanılan malzeme ve yapım tekniklerine bağlı olarak günümüzde varlıklarını sürdürmektedir. Bu köprülerde genellikle kemer formlarının tercih edilmesinin sebebi çekme dayanımı düşük doğal malzemelerden inşa edilmesidir. Çalışmada, Mimar Sinan tarafından tasarlanan 10 köprü ve bu köprülerde bulunan 48 kemer yapısı üzerinde istatistiksel bir değerlendirme yapılmıştır. Bu değerlendirmeye bağlı olarak açıklığı ve yüksekliği farklı 25 kemer sonlu elemanlar yöntemiyle modellenmiştir. Bu kemer yapılarının mafsallaşma durumları, göçme yükü, maksimum yerdeğiştirmesi, sünekliği, enerji tüketme kapasitesi incelenmiş ve regresyon analizi yapılmıştır. Çalışma sonucunda, incelenen köprü kemerleri için maksimum yerdeğiştirmeyi ve göçme yükünü veren bağıntılar önerilmiştir.

“…Material properties of masonry walls are determined by empirical formula from the literature by considering the material properties of masonry stone units and mortar constituents. Due to their complex geometric features, modelling of mosques, churches, minarets, towers and bridges involves the use of macro modelling technique [7,[22][23][29][30][31][32].…”

Historical masonry bridges generally consist of arches, spandrels walls, backfills, piers and foundations. Under the effects such as earthquake, flood and wind, the most vulnerable structural elements of bridges against out-of-plane seismic motions are spandrel walls. Increasing length and height of spandrel walls increases the vulnerability of the bridge under loads in vertical and transverse directions. The aim of this research is to examine the in-plane and out-of-plane non-linear structural responses of the spandrel walls of a historical masonry bridge. For this purpose, a historical masonry arch bridge with built in 1787 in Bartın-Turkey was chosen as the subject structure. The 3D finite element model and nonlinear seismic analyses of the bridge were performed with ABAQUS. Initially, the backfill-spandrels and backfill-arch interfaces of the bridge were modeled with and without cohesive contact. The non-linear material responses of the spandrel walls and the arch units were defined using Concrete Damage Plasticity material model and those of the backfill unit were defined with Mohr-Coulomb material model. The east-west component of 17 August 1999 Kocaeli Earthquake’s acceleration records was used in the analyses. The east-west acceleration component was applied on the bridge in-plane and out-of-plane directions during the time-history non-linear seismic analysis of the bridge. The results obtained from the analyses with and without the consideration of cohesive contact were compared to evaluate the seismic responses of the spandrel walls. As a result, cohesive interface behavior was found to significantly affect the spandrel wall response under in- plane and out-of-plane seismic forces.
