Historical structures are cultural heritage constituents that convey the traces and characteristic features of civilizations to the present days. One of these structures, which are among the monumental artefacts, are historical bridges. To protect historical buildings, 3D photogrammetric documentation of these structures, detailed determination of geometric and material properties and performing computer-aided structural analysis using appropriate modelling techniques are very important. The aim of this study is to present an effective, reliable, and fast multidisciplinary approach for the analysis of historical masonry bridges. The aforementioned approach is presented as an example for the behavior of the recently restored historical Ayvalıkemer (Sillyon) masonry arch bridge under possible loadings. Terrestrial laser scanning (TLS) was used to determine the bridge geometry with high accuracy. The point cloud data obtained from TLS was simplified and a three-dimensional CAD based solid model of the structure was created. This solid body has been formed the basis of the macro model for structural analysis. CDP material model was used to describe the inelastic behavior of homogenized structure. Thus, an analysis was carried out which presents the structural behavior of a historical bridge with high accuracy and reliability.

历史建筑是文化遗产的组成部分，将文明的痕迹和特征传达到今天。这些建筑物之一是具有纪念意义的文物，是历史桥梁。为了保护历史建筑，这些结构的 3D 摄影测量记录、几何和材料特性的详细确定以及使用适当的建模技术进行计算机辅助结构分析非常重要。本研究的目的是提出一种有效、可靠和快速的多学科方法来分析历史砖石桥梁。上述方法是作为最近修复的历史 Ayvalıkemer (Sillyon) 砌体拱桥在可能的载荷下的行为的示例。地面激光扫描 (TLS) 用于高精度地确定桥梁几何形状。从 TLS 获得的点云数据被简化，并创建了基于三维 CAD 的结构实体模型。该实体已形成用于结构分析的宏观模型的基础。CDP材料模型用于描述均质结构的非弹性行为。因此，进行了一项分析，以高精度和可靠性呈现历史桥梁的结构行为。CDP材料模型用于描述均质结构的非弹性行为。因此，进行了一项分析，以高精度和可靠性呈现历史桥梁的结构行为。CDP材料模型用于描述均质结构的非弹性行为。因此，进行了一项分析，以高精度和可靠性呈现历史桥梁的结构行为。
