In this study a comprehensive survey using faro laser scanning is performed to create a realistic 3D geometry model for subsequent seismic analysis of the bridge. The seismic response of the bridge is investigated using macro modeling approach based on finite elements. The adaptation of the Concrete Damage Plasticity (CDP) material model for masonry units and the Mohr-Coulomb material model for the backfill have been implemented. Nonlinear dynamic analyzes were then performed to identify the most vulnerable areas of the bridge. The examination of the results in terms of contour plots of tensile damage and maximum displacements has provided a thorough description of the seismic response of the entire bridge. The methodology used in this study can be considered a comprehensive basis for evaluating the seismic response and failure of historic structures.
