THE EBRO RIVER BRIDGE. A NEW CONCRETE BRIDGE FOR RAILWAYS

摘要

The bridge over the Ebro River is located on the High Speed Railway Line Madrid-Zaragoza-French Border. The bridge has an innovative deck in which we tried to adapt the concept of the metallic lattice of large railway bridges to the structural and construction domain of prestressed concrete bridges The cross section is made of a box girder whose webs contain circular voids and connected by ribs in the upper part. From the structural point of view, this is actually a Vierendeel girder. The paper will show the most relevant and specific structural aspects of this new bridge typology.
