| Abstrait: |
The majority of viaducts constructed in urban areas are concrete beam viaducts with spans of 25.0÷60.0 m. Due to the specific location of these viaducts, their elevations as well as the structural solutions applied in them are visibly accessible to the users of the transport infrastructure. When shaping such viaducts, it is thus essential to pursue their positive aesthetic reception, meeting the reasonable cost requirement. The material presented in this paper may inspire a debate binding the above-mentioned issues. Conditions for standard bridge architecture have been presented. The paper provides also examples of pier and span shaping in urban concrete viaducts (mainly prestressed concrete viaducts designed by the authors) as well as commentaries on particular solutions. Final conclusion have been drawn. |
