Abstract: This study investigates the structural behavior of the historical bridge located in the “Yukhari Bash” National Architectural Reserve Zone in Sheki, Azerbaijan, using finite element analysis (FEA) before and after its restoration. The primary objective is to evaluate the performance of the bridge under self-weight and seismic loads, following the standards of the Turkish Building Earthquake Code. The bridge, constructed primarily with limestone masonry, was analyzed using SAP2000 software. The results indicate that the structural integrity under compressive and shear stresses remained within acceptable limits both before and after restoration. However, post-restoration improvements in stress distribution and deformation were evident. This paper contributes to the preservation of historic structures through modern engineering analysis and provides insights into the appropriate restoration practices for masonry arch bridges.
