Historical masonry structures that connecting the past to the present have great importance because they represent the experiences and characteristics of various cultures. Therefore, the protection of historical structures is important. In this study, the structural response of the historical masonry Mosque was evaluated through dynamic analyses. For this purpose, the Sütlü Minaret Mosque which is located in Malatya, Turkey, was investigated. The three-dimensional model of the historical mosque was generated with ANSYS software. The material properties of the mosque were obtained with experimental tests. The time history analyses were used to obtain the seismic behavior of masonry mosque. In the time history analyses, six different strong ground motion records, including the 2020 Elazığ earthquake, were used. After the analysis, displacement and stress values in the mosque were given. The absolute peak displacement value among these earthquake records was obtained from the 1999 Düzce earthquake and the highest principal compressive and tensile stress values were determined for the 2010 Darfield earthquake. Also, the crack regions which occurred in the mosque after the 2020 Elazığ earthquake were compared with the dynamic analysis result of the 2020 Elazığ earthquake. The crack regions formed after the Elazığ earthquake are similar to the possible crack regions formed after the dynamic analysis.

“…The basic parts of the masonry bridges are arch, spandrel wall, infill material and foundation. Arch is possibly the oldest architectural shape, and it is most significant part of the masonry bridges [1]. In the literature, there were different studies about structural assessment of historical masonry bridges.…”

Historical masonry arch bridges which might be vulnerable to natural disasters are important part of the cultural heritage. Natural disasters, especially earthquakes can inflict damage to these structural systems. This paper aims to investigate a comparison of the effects of near and far-fault ground motions on the seismic response of masonry arch bridges under different earthquakes. Kalender masonry arch bridge which is located in Ergani, Turkey is selected as a numerical model. For this purpose, three-dimensional finite element model of the bridge is generated with ANSYS finite element software with macro modelling approach. Seismic response of the bridge is assessed by means of time-history analyses. The near-fault and far-fault ground motions, which have approximately equal peak ground accelerations, of 1979 Imperial Valley, 1999 Chi-Chi, 1999 Kocaeli and 2010 Darﬁeld earthquakes are considered for the analyses. Comparisons between maximum displacements, maximum and minimum stress, which were acquired from the dynamic analyses of the masonry bridge subjected to each fault effect, are obtained. The study demonstrates that far-fault ground motions are as important as near-fault ground motions and it can be used together with near-fault ground motion for further evaluation of such historical masonry bridges.

Bu çalışmada zaman içerisinde geometrik form değişikliklerine maruz kalmış tarihi Yılanlı (Leylekli) köprüsünün deprem performansı değerlendirilmiştir. Çalışmada, köprünün özgün formu ve değişime uğramış formu 3D katı model olarak ANSYS sonlu elemanlar yazılımı kullanılarak modellenmiştir. Her iki yapı için statik ve zaman tanım alanında analizler gerçekleştirilerek, gerilme ve deformasyonlar irdelenmiştir. Mimari ve estetik açıdan hiçbir şekilde olumlu karşılanmayacak olan köprü formunun değiştirilmesinin, yapının deprem performansını olumlu yönde etkilediği analiz sonuçlarından anlaşılmaktadır. Gerek statik analizden gerekse dinamik analizden elde edilen veriler asimetrik köprü modelinin daha az zorlandığını ortaya koymaktadır. Bu durumun, zaten çok rijit olan köprü yapısının form değişikliğinin yapı rijitliğinde ilave artışa sebep olmasından kaynaklandığı söylenebilir.
