| Abstract: |
The paper proposes a way in which the economy and durability of push-launched prestressed concrete bridges can be improved by fully exploiting the potential of external cables. The cables are stressed initially along the centroid of the section. After the launch the cables are deflected into efficient profiles. This method allows the user of greater span/depth ratios than current practice, and hence the range of applications can be extended. |
