Seismic assessment of a historical masonry arch bridge

Historical masonry arch bridges which are important components of the transportation in many places worldwide are invaluable part of architectural and cultural heritage. These bridges, which date back to hundreds of years, have frequently been damaged or ruined because of unexpected events such as earthquakes. In this study, earthquake behaviour of a historical masonry arch bridge which called Dutpnar is analysed using 2003 Bingl earthquake acceleration records. The bridge is modelled with three dimensional finite element software. Dynamic response of the bridge is investigated. For this purpose, displacement of the nodal point located at the top of the bridge is achieved. Also, maximum and minimum principal stress and strains are obtained and potential locations of initial damages are evaluated.
