Abstrakt: 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 from past to present. Some of the historical bridges have been deformed due to natural events and human factors and some 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 analyses are made using earthquake acceleration records obtained from past earthquakes. With the result of these studies, it is aimed to strengthen the weak parts of the structures. Therefore, 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 study, the historical Sultan Hamit I-II and III bridges in the Askale district of Erzurum province are examined. These bridges were modeled in three dimensions using the SAP2000 finite element program. First of all, static analyses of the bridges under their own weight were performed. The dynamic properties of the bridges were determined by using modal analyses. After the dynamic properties of the bridges were obtained, dynamic analyses were evaluated with timehistory analysis.
