Seismic design of a railway viaduct in high seismic zone

The design and detailing of rail viaducts for high seismic loads presents several unique challenges that are often not covered adequately by codes of practice. For instance, designers must consider the impact of the natural frequency of the structure on the safety of the train itself. The following paper outlines a practical design approach for designing typical long, multiple span, simply supported concrete viaducts for seismic events. It considers a staged design approach where the safety of the train can be guaranteed under a so-called Level 1 earthquake and the safety of the viaduct structure is checked under a higher Level 2 earthquake. The paper provides a detailed insight into the benefits of using a push over method that accounts for the ductility of the viaduct piers over a more standard force-based approach.
