Abstract
‘]
The extradosed bridge is a bridge that combines elements of a cable-stayed bridge and a prestressed
concrete box-girder bridge. This innovative design offers several advantages, including improved
aesthetics, reduced construction costs, and enhanced durability. The extradosed cable system provides
additional support to the bridge deck while maintaining a lower overall height compared to traditional
cable-stayed bridges. This feature makes extradosed bridges particularly suitable for environments
where height restrictions are a significant consideration, such as urban areas or regions near airports.
The analysis of extradosed bridges is complex and necessitates the consideration of multiple factors to
ensure the bridge is safe, stable, and functional under all anticipated loading conditions. In this study,
finite element models of an extradosed bridge are prepared using MIDAS Civil software to analyze the
longitudinal behavior of the bridge. This sophisticated modeling technique allows for a detailed
evaluation of the structural behavior of the bridge under various loading conditions, including dead
load, live load, wind load, seismic load, and more. The longitudinal analysis specifically evaluates the
bridge’s response to both vertical and horizontal loads, taking into account the interaction between the
cable system and the bridge deck. This interaction is crucial for the overall stability and performance
of the bridge, as the cables play a significant role in distributing loads and minimizing stress on the
deck. The analysis considers various scenarios and loading conditions to provide a comprehensive
understanding of the bridge’s behavior. The findings of this study provide valuable insights into the
performance of extradosed bridges. The results highlight the importance of understanding the complex
behavior of these structures for optimal design and performance. By thoroughly analyzing the
longitudinal behavior of the bridge, the study offers practical recommendations for designing and
optimizing future extradosed bridges. These recommendations can help engineers and designers to
enhance the safety, stability, and functionality of such bridges, ensuring they can withstand various
environmental and operational conditions.
