Danube Bridge Metten

The Danube Bridge Metten was completed in 1981. It was executed by Dyckerhoff und Widmann AG as a special proposal. It has a two-cell hollow box cross-section with a superstructure width of 30.0 m. The 145 m wide river span is braced with a tied chord. The tied chord is arranged in the central axis. It is constructed in prestressed concrete with dimensions of 1.35 m x 1.60 m and accommodates a total of 56 tendons with 19 strands each. The tendons are routed over the 32.8 m high pylon and anchored at both ends within the superstructure.
The superstructure was constructed using the incremental launching method. At the time of completion, the Danube Bridge Metten was the largest structure in terms of area that had been constructed using the incremental launching method.
All piers are arranged at an oblique angle to the longitudinal axis of the structure. In connection with the very wide two-cell hollow box cross-section, the verifications in the longitudinal direction of the structure must take into account, in particular, the influences from profile deformation or unequal stress on the individual webs.
The recalculation is initially carried out for recalculation stages 1 and 2 of the recalculation guideline.
