Computer aided analysis of historicalstone masonry structures:Example of Ayvalıkemer (Sillyon) Bridge structure

Anatolia has hosted many civilizations throughout history. From these civilizations to the present, many historical structures have been inherited. In these structures, historical arch bridges have a significant place role. The geography of our country, houses many rivers, as well as hosts various civilizations. For this reason, historical arch bridges were made in order to facilitate transportation by past societies are also included as cultural heritage. But these bridges have been destroyed by natural disasters, time and people until today. This thesis study has been prepared in four main titles. First, general information about historical arch bridges is given. In this general information, the introduction of historical arch bridges, historical studies on historical buildings, structural elements, damage types of bridges and geological status of the bridge to be examined are discussed. Subsequently, the importance of the restoration works to be done for the protection of these historical buildings was emphasized. Then, with the help of developing technological methods, the geometric properties of these structures were transferred to digital environment by using TLS (Terrestrial Laser Scanning) method and detailed information about the three-dimensional model for analysis was given. Finally, a computer-aided analysis of the three-dimensional model of the restored state of the historical arch bridge subject to the thesis was carried out and the results were presented.
