Seismic behaviour assessment and rehabilitation of a masonry three‐arched bridge

Abstract Many existing historical masonry arch bridges used in the road and railway networks are still service. However, most of them show a structural performance deficit due to several factors. This study deals with seismic behavior assessment an three‐arched bridge through nonlinear, non‐adaptive static analysis carried out by three‐dimensional Finite Element model. Input data were collected from variety sources. The showed risk index that was not compliance limit values suggested current European Standards. In order improve reliability bridge, traditional rehabilitation proposed designed. bottom faces arches piles strengthened reinforced concrete thin slabs jackets, respectively, all adequately connected structure using steel bar connectors. Finally, nonlinear new satisfied vulnerability verification. techniques appears be viable but unique solution improving reliability.
