The Design of an Extradosed Bridge

Bridges are attractive structures consisting of great interest in both aspects: professional and the general public one. At the end of 19. and start of 20. century, one of the most relevant contributions to bridges engineering has been the introduction of prestressed technique, aiming to be a great solution to the need of controlling stress on elements in bridges. The purpose of this paper is to discuss and analyze the design model and structural behavior of an Extradosed bridge. The strategies and factors that must be considered in the design of an Extradosed bridge are included in this paper. The structural behavior, materials utilization and structural analysis were performed in accordance with the SOFiSTiK package
