“…ANSYS program was used for the analysis and the stress distributions and displacements of the bridge was obtained. On the other hand, there are several numerical studies about masonry arch bridges in the recent literature [18][19][20][21] In this study, the historical masonry Sultan Hamit I, II and III Bridges in the Askale district of Erzurum province, those have a single span, were evaluated numerically (Figure 1). These bridges are located at close distances to each other.…”

There are many historical bridges belonging to various civilizations in our country. Historical bridges also help us understand the sociological, economic and cultural structures of civilizations that lived between the past and the present. Historical bridges have been deformed due to natural events and human factors and some of them have been destroyed. It is extremely important to know the behavior of these bridges against earthquakes, since a large part of our country is located in a region with high earthquake risk. For this reason, the dynamic behavior of structures is examined with numerical and experimental studies, and earthquake analyzes are made using earthquake acceleration records obtained from past earthquakes or artificial earthquakes. In this direction, it is aimed to strengthen the weak aspects of the structures. For this reason, it is necessary to evaluate the behavior of historical masonry bridges that have survived to the present day in order to carry out restoration and protection. In this article, the historical Sultan Hamid I-II and III bridges in the Askale district of Erzurum province are discussed as a numerical application. These bridges were modeled in three dimensions using the SAP2000 finite element program. First of all, static analyzes of the bridges under their own weight were made. Then, the dynamic properties of the bridges were determined by making modal analyzes. After the dynamic properties of the bridges were determined, dynamic analyzes were made in the time period.

In this study, the effect of the variation of the arch form in thickness and height on the bridge was investigated as a numerical analysis. For this purpose, the historic Antik Iscehisar Bridge located in the Iscehisar district of Afyonkarahisar in the Aegean Region was elected as a numerical application. The bridge was subjected to its own weight and moving load as a static analysis. For dynamic analysis, the effect of 10 different fault movements with historical character obtained from The Pacific Earthquake Engineering Research Center (PEER) on the bridge was investigated. The areas of principal stress and deformation resulting from the applied analyses were determined. Contour diagrams, tables, and charts were given in a comparative manner based on the results of the analysis applied to the bridge. At the end of the analysis, it was observed that the displacements decreased as the arch thickness increased under its own weight in the bridge. In addition, under the influence of live loads and earthquakes, it was observed that the displacements decrease as the arch thickness increases. A seismic reliability assessment was made using the performance criteria provided in this study. If the security level is below what it should be, reinforcement applications can be designed. Accordingly, future maintenance and monitoring planning can be made.

“…Stress regions of the bridge was investigated after earthquake, flood, and traffic loads. Akın et al [17] assessed the seismic behaviour of a historical masonry bridge under different damping types. For this purpose, mass proportional, stiffness proportional and Rayleigh damping types were used.…”

Historical structures which are cultural heritage have been frequently damaged or ruined because of unexpected events such as earthquakes. Masonry arch bridges constitute a significant part of historical structures. In this study, the single-span Murat Bey Bridge in the province of Kütahya, built in 1460, was selected as a numerical application. Three dimensional finite element model of the bridge was generated with SAP2000 finite element program. The dynamic characteristics of the bridge were obtained by modal analysis method. Firstly, static analysis of the bridge under its own weight was carried out. Then, time-history analysis method was used for seismic evaluation of the bridge. For this purpose, the acceleration records of the 1998 Adana, 2003 Bingöl, 2011 Van and 2020 Elazığ earthquakes were taken into consideration. As a result of the dynamic analyses carried out, the displacement and stress graphs occurring on the bridge were examined. The highest displacement and stress values on the historical bridge were obtained from the acceleration records of the 2011 Van earthquake.
