Etude D’un Pont A Poutre Caisson En Beton Precontraint
Résumé: The purpose of this work is to study the deck of a prestressed concrete box girder bridge. The work is located in the wilaya of Tlemcen and it is one of the many works that have been made as part of the East-West Highway project. This structure, with a total length of 110m, is made of 3 dependent spans (Hyperstatic system) in prestressed concrete box girders cast in situ. A justification for the chosen variant was made, followed by a detailed study on the design and calculation of the various elements making up the infrastructure and the superstructure of this structure according to the different demands: permanent actions, actions due to overloads of traffic and energy, equipment and seismic actions. Numerical modeling and calculation processing was performed using the CSI Bridge software. The results thus obtained are translated by an adequate reinforcement of the various elements composing the work.
