Then the studies which have been made before, are related to the masonry arch bridges are mentioned. After that general information about masonry arch bridges is given and short history of masonry arch bridges is addressed. In the last part of the section, required formulations are provided for the finite element method and seismic analysis. Studies which are made within the thesis are taken place in the second part. After detailed information about chosen bridge were given, the results of dead load, dead and live loads, dead-live and earthquake loads analyses for before and after restoration case are given with contour diagrams. Then whole results are given with tables. In the third section, the results and suggestions which are obtained from study are listed. In the last chapter, it is given sources benefited and suggestions.
