"Bridges constitute the critical part of transportation systems and their. functionality should be preserved during major earthquakes. The implementation of. comprehensive guidelines for the seismic assessment and retrofit of existing bridges. requires the understanding of complex local and global behavior under moderate to. large earthquakes. The RETRO TA project has been funded by the European. commission within the SERIES project and it focuses on an old portal frame bridge. (Rio-Torto Viaduct), not properly designed for seismic actions. Main objectives of the. current research activity are to assess the seismic vulnerability of Rio-Torto Viaduct. through Pseudo Dynamic (PsD) testing and perform numerical analysis to investigate. the effectiveness of the proposed retrofitting techniques. A proper Seismic hazard. assessment (SHA) is one of the key steps that needs to be conducted to guide the. selection of earthquake ground motion records for nonlinear time-history analysis and. similitude laboratory tests. This paper elaborates the selection and scaling procedures of. the ground motion records within a performance-based design framework as defined in. NTC-08."
