摘要

Bridges that can be constructed with prestressed concrete decks economically might lead to difficulties in some spans. These difficulties for example can be river-crossings. Here the question arises what is the best concept for the superstructure. The rigid connection between prestressed concrete bridge decks and composite bridge decks lead to economical solutions. Two applications are given: The new Isarbridge in Dingolfing/Bavaria shows the combination of prestressed concrete bridge decks in the approaches and composite bridge decks in the river area. In the approach-parts the decks are constructed with prefabricated pc-beams and the plate structure is cast in place. The longer spans are built as composite constructions. For the plate structure of the composite part semi-prefabricated concrete elements are used. While the Isarbridge is a beam bridge in both parts of the decks the river Donaubridge in Vilshofen/Bavaria connects prestressed concrete bridge decks with an arch bridge deck in the middle span. The topics of this article are the special problems in the connection zone.
